Mercedes Benz SLR Mclarens Most Advanced Racing Cars
- Black Mercedes-Benz SLR McLaren
Marcedes-Benz SLR McLaren has been on world fasted and most expensive cars lists for quite a while now. This car is a fascinating result of collaboration between two well-known car brands: Marcedes and British race car legend McLaren. The delightful SLR McLaren is probably the most sophisticated and comfortable of all street-legal race cars to date. In 2007 most expensive car list this supercar is most likely going to be replaced by its succcessor Marcedes-Benz SLR 722 Edition.
Mercedes-Benz SLR McLaren specs
- Top Speed: 207 mph / 334 km/h
- 0-60 mph: 3.6 seconds
- 0-100 mph: 7.6 seconds
- 0 - 1/4 Mile: 11.6 sec.
- Engine: V8 5.5 liter 626 bhp @ 6,500 rpm
This supercar is definitely fast. SLR McLaren sports a 626-horsepower supercharged 5.5-liter V8. Also, it has a full carbon-fiber monocoque, features crash structures and body panels. And with the supercharge V8 engine, you can see the Mercedes-Benz SLR McLaren go from naught to 60 miles per hour in less than 3.6 seconds. Top speed has been measured to exceed 200 mph, a feat that can only be achieved by very few even among the high performance sports cars. It was the high-performance division of Mercedes-Benz which created the V8s. The AMG were the ones who hand-build the supercharged V8 engines with top notched precision and quality. It is not at a big surprise to see the supercharged 5.5 (5,439 cc) liter dry sumped 90 degree V8 engine to produce around 466.8 kW at 6,500 rpm (626 hp) and 780 N•m (575 ft•lbf) torque at 3,250 - 5,000 rpm. The numbers maybe daunting but the sound of the engine will appease the minds of those who long for the perfect high performance cars.

2016 Mercedes Maybach S Class
At the world première in Guangzhou and the presentation in Los Angeles, the new Mercedes-Maybach S-Class is being unveiled almost simultaneously in its two key markets of the USA and China. The vehicle makes its début at Auto Guangzhou and the Los Angeles Auto Show just hours apart. At 5453 mm long and with a wheelbase of 3365 mm, the flagship of the Mercedes-Benz model range is 20 cm larger in both dimensions than the S-Class Saloon with long wheelbase. Rear passengers benefit from this increased size as well as from standard equipment that includes executive seats on both left and right and other exclusive details such as innovative voice amplification. In the rear, the Mercedes-Maybach S-Class is also the worlds quietest production saloon car.
"The history of prestige vehicles made by Daimler extends back to the earliest days of the motor car. We have now commenced a new chapter with the Mercedes-Maybach S-Class," points out Ola Källenius, member of the Divisional Board of Mercedes-Benz Cars responsible for sales. "As an addition to the portfolio of S-Class saloons, the Mercedes-Maybach S-Class sets new standards in the luxury segment. The vehicle satisfies the very highest requirements in terms of exclusivity appointments and comfort."
"Perfection down to the last detail and a new dimension in seating and resting comfort for the rear passengers are the hallmarks of the new Mercedes-Maybach", says Professor Dr Thomas Weber, Member of the Board of Management of Daimler AG with responsibility for Group Research and Mercedes-Benz Cars Development. "Our exceptionally successful new S-Class already defines the pinnacle of automotive engineering in a host of technical disciplines such as safety, efficiency, climate control and noise characteristics. The Mercedes-Maybach now sets the benchmark in the luxury segment even higher."
Mercedes-Maybach: a new sub-brand offering peerless exclusivity
The Mercedes-Maybach S-Class melds the perfection of the Mercedes-Benz S-Class with the exclusivity of Maybach. Mercedes-Maybach motor cars epitomise peerless exclusivity. Some of the features that distinguish these vehicles from production models include extra spaciousness with lavishly designed, prestigious interiors offering extensive scope for individualisation. As a result, the cars fulfil the requirements of even the most discerning customers worldwide.
Mercedes-Maybach is not an equipment line – it is a sub-brand that in future will provide Mercedes-Benz vehicles in an even more exclusive form. Alongside Mercedes-AMG, Mercedes-Maybach is thus the second sub-brand in the Mercedes-Benz brand world. Providing both prestige and exclusivity, it is aimed at customers for whom status is important.
The market launch of the Mercedes-Maybach S-Class is scheduled for February 2015. The top-of-the-range model is the Mercedes-Maybach S 600. Its V12 biturbo engine has an output of 390 kW (530 hp). With a displacement of 5980 cc, the maximum torque of 830 Nm is available from 1900 rpm. The V8 biturbo engine in the Mercedes-Maybach S 500 generates an output of 335 kW (455 hp) from a displacement of 4663 cc. Its peak torque is 700 Nm. NEDC combined fuel consumption for the saloon is just 8.9 litres/100 km (premium petrol). CO2 emissions are 207 g/km. The Mercedes-Maybach S 500 4MATIC will also be available from June 2015.
Inside the Mercedes-Maybach S-Class, the level of wind noise is impressively low and in the rear, despite the large windows, betters even the quietest car in the world – the S-Class Coupé. For passengers in the rear, the Mercedes-Maybach S-Class is the worlds quietest production saloon car.
In its exterior design, the Mercedes-Maybach S-Class combines stylish, effortless superiority with trend-setting exclusivity. The vehicle makes modern luxury come alive in an exceptional way. Along with the extended wheelbase, emphatic lines suggest power and dynamism. Due to the sidewalls special design, characteristic design elements for the S-Class are retained such as the sweeping, dome-shaped roofline.
The key distinguishing feature is the new side line: by comparison with the long-wheelbase version of the S-Class, the striking rear door has been shortened by 66 mm and therefore appears to meld seamlessly into the overall composition. The door has no triangular window because this has been relocated into the C-pillar. As a result, the rear seats are situated beyond the door cutout, which creates a feeling of exceptional privacy and exclusivity. The elegant Maybach Manufaktur logo – a double M inside an arched triangle – adorns the C-pillars on both sides.
In the interior of the Mercedes-Maybach S-Class, passengers are enveloped in lounge-style, modern luxury. With its clear architecture, refined materials and stylish controls, the vehicle embodies a sensuous elegance. For an exclusive look, the front centre armrests with nappa leather or exclusive nappa leather upholstery feature embossed Maybach crests. Another special feature in the dashboard is the analogue clock with an IWC design.
The high quality standards of the Mercedes-Maybach S-Class are impressively evident from the doors, which even have handstitched door trim as part of the standard equipment. This extravagance is part of the interiors luxurious, hand-finished "Manufaktur" character. Exclusive features used in the Mercedes-Maybach S-Class are trim parts in wood/chrome and leather at shoulder height in the door panels, chrome-plated tweeter grilles and fibre-optic cables for the ambience lighting to the side on the armrest. Together they create a unique atmosphere conveying a sense of capacious style.
As the flagship of the Mercedes-Benz model range, the Mercedes-Maybach S-Class satisfies the very highest requirements in terms of luxury appointments and comfort. In addition to all the amenities of the conventional S-Class, a number of exclusive interior touches underscore the Mercedes-Maybach S-Classs ambition to lead. These include the exclusive Maybach perfume AGARWOOD for fragrancing as part of the AIR-BALANCE package and two silver-plated, handcrafted champagne flutes (both optional extras). Voice amplification is a novel function emphasising the Mercedes-Maybach S-Classs positioning as a chauffeur-driven vehicle, which makes it much easier for occupants in the front to communicate with the rear passengers. The Burmester® high-end 3D surround sound system offers a unique optical and acoustic experience. As a visual highlight, the tweeters in the rear doors of the Mercedes-Maybach S-Class are particularly sophisticated and can also be moved towards the passengers in a spiral motion.
A sense of spaciousness: setting new benchmarks for sleeping and resting comfort in the rear
The Mercedes-Maybach S-Class is specifically designed to be chauffeur-driven. For the driver and any front passenger, there have been no compromises compared with a "normal" S-Class. Here, however, the real sense of spaciousness is to be found in the rear. The benefits of extending the wheelbase by 200 mm are felt entirely in the back of the vehicle where the specification has been refined even more. Due to the roofline, it was also possible to further raise the head clearance.
Here is a comparison of two important dimensions relating to comfort:
V 222 | X 222 | |
Effective headroom in rear* (mm) | 951 | 963 |
Kneeroom in rear* (mm) | 166 | 325 |
* With executive seat and sliding sunroof
A clear indication that the owner of the Mercedes-Maybach S-Class will typically be found in the second row are the standard-fit executive seats on the left and right. These rear seats offer a unique level of comfort thanks to a special adjustment kinematics system. In contrast to the norm, the backrest is adjusted separately while the footwell and seat reference point remain unchanged. The cushion can be adjusted separately, with inclination and horizontal adjustment combined.
For the executive seats, the maximum backrest angle is 43.5 degrees. The most upright backrest position of 19 degrees allows relaxed working in the rear. The reclining seats feature a calf support, which is freely adjustable for length and angle. As standard, the luxury head restraints come with an extra cushion.
The Chauffeur package is also part of the standard equipment. A "chauffeur position" for the front passenger seat is one of the key components: due to changes to the kinematics system, the rear seat occupant on the front-passenger side has 77 mm more footroom compared with a normal front passenger seat in the furthest forward seat position. In addition to this "chauffeur position", the front passenger seat can be folded forward and the rear seat placed in an extended recline position for breaks. EASY ADJUST luxury head restraints come as standard for the driver and passenger, and the one on the front-passenger side is folding. For the rear passenger, the Chauffeur package also includes a heel support, which extends from under the front passenger seat. This allows a reclined position that sets new standards in the automotive sector with respect to sleeping and resting comfort.
Individual seat functions in the rear, and those of the chauffeur seat, are of course electrically operated via the typical Mercedes control panels in the rear doors. The rear armrest has a double cup holder, stowage space and wood trim.
As an option, it is possible to boost comfort for rear passengers even further. The Rear Seat Comfort package includes individually adjustable multicontour seats, for example, and an ENERGIZING massage function based on the hot-stone principle.
The First-Class rear suite (centre console in the rear) is a visual continuation of the front console on the centre tunnel. It is equipped with innovative thermo cup holders, which use Peltier technology to cool or warm drinks over a longer period of time.
Like an aircraft seat, the centre console is available with two tables which can be easily folded in or out using one hand. Two articulated joints on the stem and underside of the table enable it to be adjusted to almost any position. The table supports and surface are made of a light alloy, combining great stability with a high-quality look. The table surfaces have leather inserts to provide a comfortable writing surface.
To deliver maximum climatic control in the rear compartment, there is a second, standard-fitted THERMOTRONIC automatic climate control system in the rear with two additional climate zones for the rear seats. A control panel on the back of the centre console allows the temperature and air distribution to be set individually for the left and right sides. For targeted climate control, there are two nozzles in the centre console and also on the B-pillars and in the rear footwell. Using COMAND Online, the driver can conveniently adjust the automatic climate control system for the back of the vehicle too.
As exclusive optional equipment (standard in the Mercedes-Maybach S 600), there is the AIR-BALANCE package including ionisation, enhanced air filtration and fragrancing with AGARWOOD, the exclusive Maybach perfume (see section on appointments).
Aeroacoustics: in the back of the worlds quietest production saloon
Inside the Mercedes-Maybach S-Class, the level of wind noise is impressively low and, despite the large windows, betters even the quietest car in the world – the S-Class Coupé. For passengers in the rear, the Mercedes-Maybach S-Class is the worlds quietest production saloon car. Extensive measurements were also taken in experimental vehicles considering the fully reclined position in the rear. That is because positioning the passenger away from the side windows and towards the rear window and triangular windows creates a new acoustic situation.
Special seals optimise the noise insulation, thereby ensuring excellent aeroacoustic performance in the rear. These include seals over the C joints in the rear doors, which have a hose profile rather than the usual lip seal, as well as bonded triangular windows with a special seal.
Other measures in the rear compartment are a generous area of insulation around the single seats extending from the seat cushion over the rear panel to the parcel shelf. Intelligent air ducting around the parcel shelf reduces the intrusion of noise, and sealed inertia reels on the seat belts prevent possible disturbing sounds. The textile underbody and wheel arch lining have an insulating and absorptive effect, which reduces high-frequency tyre noise in the interior.
A new aeroacoustic wind tunnel at the Mercedes-Benz Technology Centre in Sindelfingen became operational in September 2013 and played a crucial part in achieving excellent, quiet running. For example, the conveyor belt/balance system there is integrated into a turntable with a diameter of twelve metres. This means that test vehicles can also to be subjected to an angled flow of air in order to simulate crosswinds.
As a result, experts in aeroacoustics were able to study the perfect design for the door structure of the Mercedes-Maybach S-Class under wind load. The door seal must fit closely even when subjected to a constant or gusty sidewind such as would be encountered when passing a truck, on bridges, in wooded areas or when driving on a coastal road. Despite negative pressure on the side away from wind, the door must never be pulled more than a few millimetres away from the seal. Large doors are particularly susceptible to this phenomenon because strength is a product of (negative) pressure and area.
Aerodynamics: many details with optimum flow
- With a Cd value of 0.26, the Mercedes-Maybach S-Class maintains the brands leading position in the area of aerodynamics.
- A whole raft of aerodynamic optimisations has been implemented:
- Wheel spoilers with aerodynamically optimised contour ahead of the front wheels
- Large area of cladding on the rear axle
- Aerodynamically efficient design of the front and rear aprons and the rear spoiler
- Optimised exterior mirror design with mirror base
- Sealed headlamp surrounds
- Improved sealing of the radiator section and flow properties to make efficient use of the available cooling air
- Streamlined water drainage channels
- Speed-dependent lowering of the vehicle by up to 20 mm
- Spoiler lip on each tail light
- Aerodynamically optimised underbody with extensive engine compartment and underbody panelling
Exterior design: elegant and exclusive
In its exterior design, the Mercedes-Maybach S-Class combines stylish, effortless superiority with trend-setting exclusivity. The vehicle makes modern luxury (in the truest sense of the word) come alive in an exceptional way. Along with the extended wheelbase, emphatic lines suggest power and dynamism. Due to the sidewalls special design, characteristic design elements for the S-Class are retained such as the sweeping, dome-shaped roofline. The key distinguishing feature is the new side line: by comparison with the long-wheelbase version of the S-Class, the striking rear door has been shortened by 66 mm and therefore appears to seamlessly meld into the overall composition. The door has no triangular window. This has been relocated into the C-pillar. As a result, the rear seats are situated beyond the door cutout, which creates a feeling of exceptional privacy and exclusivity. The triangular windows and other glass areas alike have chrome surrounds. The B-pillar is also covered in chrome. The elegant Maybach Manufaktur logo – a double M inside an arched triangle – adorns the C-pillars on both sides. What is more, exclusive 20-inch (50.8 cm) forged, light-alloy wheels are available for the Mercedes-Maybach S-Class. Instead of delicate spokes, their design features large surfaces to underline the flagship models high-quality look. Overall the Mercedes-Maybach S-Class is 207 mm longer than the S-Class with long wheelbase. 200 mm of this is the result of the extension between the B and C-pillar. All this additional space is used to boost comfort for rear passengers.
Subtle yet noticeable changes in both the front and rear area differentiate the longest S-Class from its smaller siblings. Three double louvres in chrome within the radiator trim have a formative influence on the Mercedes-Maybach S-Classs elegant look. Additional vertical chrome trim discreetly but deeply underlines the special appeal of this extraordinary vehicle. This theme is taken up once again in the design at the tail end.
The key features of the front end design:
- Dominant radiator trim with large radiator opening and three double louvres in chrome
- Subtle vertical chrome trim
- Double trim in the air intakes on the right and left
- Double trim in the bottom end piece of the bumpers
The emphatic design for the sides draws to an effective conclusion at the rear. The chrome double louvres deployed at the front are continued in the rear area, emphasising high quality and elegance.
Key features of the rear end design:
- Horizontal lines emphasise the vehicles width
- Two tailpipe trim elements in chrome integrated into the bumper with vertical partition
- Chrome double louvres in the bottom section of the bumper covering add the perfect finishing touch to the vehicle
- Maybach lettering on the boot lid (mounted on the left in direction of travel)
Interior design: the essence of modern luxury
"To create only the very best from the very best – a car that fulfils every last wish and stands out for its supremely refined elegance and power" is the aim according to a Maybach brochure dating from 1930. This continues to be the case today. In the interior of the Mercedes-Maybach S-Class, passengers are enveloped in lounge-style, modern luxury. With its clear architecture, refined materials and stylish controls, the vehicle embodies a sensuous elegance.
The Exclusive trim package, which is fitted as standard, increases the sense of perceived value still further, particularly in the rear of the vehicle. Sensuously curved, fine-wood trim with a handcrafted feel surrounds the entire rear seating system. The seat-back lining, doors and nozzle coverings are resplendent in fine wood.
For an exclusive look, the front centre armrests with nappa leather or exclusive nappa leather upholstery feature embossed Maybach crests (and also the armrests in the rear in conjunction with the First-Class rear suite). Another special feature in the dashboard is the analogue clock with an IWC design. The numbers are individually milled and applied, underlining the analogue clocks exclusive design. Both the numbers and indicators are made of fine metal. The high quality standards of the Mercedes-Maybach S-Class are evident from the doors, which even have handstitched door trim as part of the standard equipment (in nappa leather with exclusive leather as an optional extra). This extravagance is part of the interiors luxurious, hand-finished "Manufaktur" character. Exclusive features used in the Mercedes-Maybach S-Class are trim parts in wood/chrome and leather at shoulder height in the door panels, chrome-plated tweeter grilles and fibre-optic cables for the ambience lighting to the side on the armrest. Together they create a unique atmosphere conveying a sense of capacious style.
The models: with V12 and V8 engines plus 4MATIC
The top-of-the-range model is the Mercedes-Maybach S 600. Its V12 biturbo engine has an output of 390 kW (530 hp). With a displacement of 5980 cc, the maximum torque of 830 Nm is available from 1900 rpm. The Mercedes-Maybach S 600 completes the sprint from 0 to 100 km/h in 5.0 seconds, while the top speed is 250 km/h (electronically limited). The most important features of the V12 engine are the all-aluminium crankcase, one-piece chain drive, forged crankshaft in high-grade quenched and tempered steel, forged pistons, dedicated ignition coil with multispark ignition, hollow-stem outlet valves filled with sodium and a low-temperature coolant circuit with separate expansion reservoir.
The V8 biturbo engine in the Mercedes-Maybach S 500 generates an output of 335 kW (455 hp) from a displacement of 4663 cc. Its peak torque is 700 Nm. NEDC combined fuel consumption for the saloon is just 8.9 litres/100 km (premium petrol). CO2 emissions are 207 g/km. The Mercedes-Maybach S 500 4MATIC will also be available from June 2015. Permanent all-wheel drive improves traction and driving stability, particularly when road conditions are difficult in winter, for example. The Mercedes-Maybach S 500 is equipped as standard with new 9G-TRONIC, the worlds first nine-speed automatic transmission in the premium segment. Its broad ratio spread (9.15) for gears one to nine allows an overall reduction in engine speed a key factor behind the high level of energy efficiency and ride comfort. Shortened shift and reaction times ensure optimum spontaneity combined with outstanding ease of shifting. The Mercedes-Maybach S 600 comes with the latest evolution of the 7G-TRONIC PLUS automatic transmission.

Bodyshell: exemplary stability
From the outset, the bodyshell for the Mercedes-Maybach S-Class was developed alongside the two shorter S-Class models and thus benefits from the innovative solutions deployed there. The new S-Class has already won the worlds most prestigious award in car body construction: at the annual EuroCarBody Conference in Bad Nauheim in October 2013, it beat off the competition to achieve first place. Decisive factors included the highly innovative aluminium hybrid construction of the S-Class vehicle body featuring various materials such as cast aluminium and high-strength steels, along with the efficient use of appropriate joining technology such as aluminium MIG welding, self-piercing riveting and the first use of RobScan welding on aluminium in large-scale production.
Based on this exemplary substructure the Mercedes-Maybach bodyshell, which has the largest side panel made in series production in a single piece, was optimised further. Repeated reinforcements at the base of the B-pillar – the engineers talk vividly of the shoe-shaped reinforcements on the S-Class with long wheelbase turning into "boots" here on the Mercedes-Maybach – and at the transition from the almost square door cutout to the wheel arch provide additional rigidity. Despite the much longer length, NVH conduct is trend-setting for its class. Among other factors, the attachments for the reclining seats in the rear have been enlarged to avoid subtle vibrations – a modification that likewise benefits the S-Class with long wheelbase.
Safety: intelligent assistance systems and innovations for the rear
Like the S-Class, the Mercedes-Maybach S-Class is available with numerous new assistance systems that make driving even more comfortable and safer. Intelligent Drive systems include PRE-SAFE® Brake with pedestrian detection, DISTRONIC PLUS with Steering Assist and Stop&Go Pilot, Brake Assist BAS PLUS with Cross-Traffic Assist, Active Lane Keeping Assist, Adaptive Highbeam Assist Plus and Night View Assist Plus.
In the shape of the seat belt buckle extender, beltbag (both part of the PRE-SAFE® rear package) and seat cushion airbag, the Mercedes-Maybach S-Class possesses further innovative safety features that are not even available as options from other brands.
Executive seats in the rear as standard come with the innovative seat cushion airbag. The airbag is located under the seat cushion upholstery, but on top of the plastic seat shell, which is moved by the seat mechanisms. This means that the airbag is always in the right position relative to the occupant.
In an accident, with the occupant in a reclined position on a flat seat cushion, without additional measures there would be a danger of the pelvic area sliding beneath the belt strap (submarining). This can be prevented by the cushionbag, as it raises the front section of the seat cushion upholstery. The airbag is only activated if the seat is in the reclined position during a crash. It is not activated in the upright position, as there is then no danger of submarining.
Reducing belt slack: the seat belt buckle extender
In the seat belt buckle extender, an electric motor automatically raises and lowers the buckle. This makes for easier seat belt attachment and reduces any belt slack in the area of the pelvis and thorax. Passengers are also secured more firmly in both the sideways and lengthways direction. The seat belt buckle extender follows the integral Mercedes-Benz safety concept. By systematically implementing safety as a priority, this concept covers all phases of automobile safety: from safety while driving to safety in hazardous situations, and from protection in an accident to minimisation of the consequences.
The innovation is classic Mercedes-Benz, improving safety and comfort in one. This is because fastening seat belts in the rear is also made much simpler: the seat belt buckle emerges from the upholstery when the rear doors are opened and is provided with an illuminated insertion slot. Simplifying use of the seat belt in this manner may increase the percentage of rear passengers who buckle up. It also makes it easier to assist children or people who require help in fastening their seat belts.
The seat belt buckle extender is furthermore integrated into the PRE-SAFE® anticipatory safety system. This means that in cases where PRE-SAFE® is activated in critical driving situations, there is also reversible belt tensioning in the rear via the seat belt buckle extender. The restraint system and passengers are thus better prepared for a possible accident situation. In this way, the seat belt buckle extender complements the pyrotechnical belt tensioning which has featured as standard on all outer rear seats in Mercedes-Benz vehicles for many years now, and is triggered in the event of an impact exceeding a certain severity.
The seat belt buckle extender is a motorised belt buckle which can be extended upwards by up to 50 mm and retracted by up to 40 mm. The belt buckle is attached via a cable to a nut which runs on a spindle, translating the electric motors rotary movement into a linear movement.
An airbag for seat belts: the beltbag
The beltbag is an inflatable seat-belt strap that reduces the load on the ribcage in a front impact and is thus able to reduce the risk of injury to passengers in the rear. Because dummy measurement technology is not capable of quantifying the benefits resulting from a wider belt strap, such as the lower force exerted on occupants in the rib area in particular, the safety experts at Mercedes have been working extensively with virtual human models too. Such computer-generated models make it possible to obtain detailed findings on the biomechanical strain during an accident.
Should the crash sensors detect a severe frontal impact, the airbag control unit triggers deployment and inflation of the beltbag. A gas generator then inflates the multi-layered belt strap with tear seams to nearly three times its normal width. The resulting larger surface area is able to better distribute the force acting on the seat occupant. This lowers the risk of injury.
The beltbag is used in exactly the same way as a conventional seat belt. The belt straps design is different from that of the standard belt though, and received top marks in practical trials for being extremely comfortable to wear and for its extra-soft belt strap edge.
Other protective measures: windowbag and thorax-sidebag
If the central electronic control unit detects a side crash, the windowbag and thorax-sidebag are deployed on the side of the vehicle on which the impact occurs. To ascertain the lateral acceleration, the central crash sensor has support from exterior satellite sensors located at the base of the B-pillars. Pressure sensors in all four doors also help to estimate the severity of the impact.
Equipment and appointments: an exclusive perfume and handcrafted champagne flutes
As the flagship of the Mercedes-Benz model range, the Mercedes-Maybach S-Class satisfies the very highest requirements in terms of luxury appointments and comfort. In addition to all the amenities of the conventional S-Class, a number of exclusive interior touches underscore the ambition to lead of the Mercedes-Maybach S-Class. Here is an overview of the most important exclusive highlights:
- Of course, the Mercedes-Maybach S-Class comes with the option of selecting the AIR-BALANCE package which includes fragrancing, ionisation and even more efficient filtration compared with the basic vehicle. A premium room fragrance has been designed exclusively for this model and the AGARWOOD bottle itself is adorned with Maybach lettering. Agarwood speaks of the centuries-old tradition of perfume. Oud derived from the wood of the Agar tree has long been one of the most precious ingredients – more valuable even than gold – and lends this fragrance its inimitable presence. The luminous golden warmth of resin marries with a striking woodiness, richly contrasted with smokiness. With its refined and elegant character, agarwood makes a statement.
- Any journey in the Mercedes-Maybach S-Class can be celebrated in style with two high-quality, handcrafted champagne flutes (optional extra). These silver-plated flutes have been made for the on-board bar by Robbe & Berking, silversmiths in Flensburg, Germany. The prestigious company has a long tradition and well over half of the 200 largest yachts in the world carry silver from Robbe & Berking. Fine restaurants around the globe with several hundred Michelin stars between them are also customers of this luxury brand.
- As standard the Mercedes-Maybach S-Class is fitted with a panoramic sliding sunroof. This roof system and its large glass areas make for an especially bright and friendly ambience in the interior. It consists of a fixed panoramic glass roof in the rear section and a top-sliding power sunroof so that the interior can be ventilated as desired. For the first time, the sliding sunroof is available with optional MAGIC SKY CONTROL technology from Mercedes-Benz: the glass can be switched to light or dark at the touch of a button (optional extra for the Mercedes-Maybach S 600).
- Small roller sunblinds for the triangular windows in the C-pillar reflect the great attention to detail. Together with the electric roller sunblinds in the rear doors, they protect passengers in the rear from prying eyes and direct sunlight if desired. When not in use, the roller sunblinds for the triangular windows are concealed out of sight in the side panels. In conjunction with the electric roller sunblind for the rear window, the roller sunblinds for the triangular windows and the rear doors form part of the standard-fit Sun Protection package. The continuous business console, part of the optional First-Class rear suite, is longer than in the normal S-Class and offers extra stowage space.
- A range of exclusive paintwork is available as an option for the Mercedes-Maybach S-Class. These paint finishes are produced as part of a "Manufaktur" process (hand-finishing section) at the plant in Sindelfingen. After the first clear coat is applied, the surface of all vehicles is roughened (intermediate sanding) and then a second and final clear coat is painted on. This adds extra depth to the paint finish.
- In addition to the leather options for the S-Class, a designo roof liner in nappa leather is available exclusively for the Mercedes-Maybach. The leather trim extends to sunblinds, roof grab handle, pillar trim, both vanity mirrors in the rear with diamond quilting pattern, and the frames of the Burmester 3D loudspeakers. Elaborate topstitching on the three interior colours of nappa leather available (black, porcelain and crystal grey) attest to the high level of craftsmanship involved in each vehicles fabrication.
"Piano lacquer flowing lines" trim will be available from mid-2015. Derived from piano lacquer trim, 0.8 mm wide lines are milled into the wood veneer to accentuate the form using a special "Manufaktur" (hand-finishing) process. Lighter stripes appear from the plastic layer below and create an extremely high-quality sense of visual depth. Once worked in this particular complex way, the trim is then painted with a high-gloss finish and polished. The result is discernible differentiation from standard.
Voice amplification: convenient communication from front to rear
Voice amplification is a new function underscoring the Mercedes-Maybach S-Classs positioning as a chauffeur-driven vehicle. This innovative function makes it easier to communicate with the rear passengers from the front. The two microphones in the interior mirror are also used to pick up speech for the handsfree telephone function. These signals are then discreetly amplified depending on the amount of driving noise, and continuously adjusted for the speakers volume and the ambient noise level.
The rear loudspeakers in the doors and in the parcel shelf are used for playback. Key considerations for the developers at Mercedes-Benz were ensuring very clear speech along with natural spatial sound and exactly the same ambience.
Voice amplification comes as standard in conjunction with the Burmester® surround sound system and the Burmester® high-end 3D surround sound system. The function is activated and deactivated under "Vehicle settings" in the COMAND menu. Voice amplification is paused during a telephone call or when using LINGUATRONIC. If the volume of a media source in the background exceeds a certain threshold, voice amplification stops. The threshold is set for relaxed conversation with background music. To prevent disturbing sounds, voice amplification only works when the doors, side windows and panoramic sliding sunroof are closed.
When developing and fine-tuning the voice amplification function, the engineers paid special attention to avoiding what is known as the Lombard effect. This is a speakers tendency to increase their pitch as well as their volume when there is background noise.
Wideband speech: HD-quality telephone calls
When making calls using a mobile phone via Bluetooth®, wideband speech technology (also known as HD Voice) provides better, more natural voice quality. This standard transmits voice over a wider frequency range. In good conditions this will be in a range from 50 to 7000 Hertz rather than 200 to 3400 Hertz previously. Telephone calls become considerably easier to understand, especially in environments like a vehicle where background noise is prevalent.
Burmester® sound systems: specially tuned and also set up for the rear of the vehicle
As alternatives to the standard sound system with ten loudspeakers including the innovative Frontbass system, two very high-quality audio systems are available which were developed together with high-end audio specialist Burmester: the Burmester® surround sound system and the Burmester® high-end 3D surround sound system. Both are, of course, tuned specifically to the sound situation inside the Mercedes-Maybach S-Class.
The Burmester® high-end 3D surround sound system offers a unique optical and acoustic experience. As a visual highlight, the tweeters in the mirror triangle of the drivers door and their counterparts in the rear doors are particularly sophisticated in the Mercedes-Maybach S-Class. They rotate through 360 degrees when the head unit is turned on, moving ten millimetres towards the passengers in a spiral motion. This movement aligns the tweeters to give the optimum sound impression. If the ambience lighting is switched on, the tweeters are illuminated in one of the seven available colours.
The Burmester® high-end 3D surround sound system provides its unrivalled listening experience by virtue of 24 high-performance speakers and 24 separate amplifier channels with a total output of 1540 watts. Its intelligent combination of analogue and digital amplifier technologies leads to an unparalleled mix of fine, natural sounds and high power reserves.
Popular with buyers and the media: the S-Classs success
Just a short time after the model change, the new S-Class has already taken the top sales position in its segment worldwide. Since then it has consistently remained on the path of success: one year after the market launch in all core markets, Mercedes-Benz has delivered more than 100,000 S-Class vehicles to customers. The car has also attracted numerous accolades from the media. For example, international motoring journalists this year chose the S-Class as "World Luxury Car". When selecting the best cars of 2014, the readers of trade journal "auto, motor und sport" declared the saloon the winner in its segment. Specialist American magazine "Ward’s Auto World" has honoured the Mercedes-Benz S-Class for its outstanding interior design. In 2013 the S-Class received the coveted title of "Car Of The Year" in China, an important sales market. That same year, 320,000 readers of AUTO BILD and COMPUTER BILD chose the S-Class as the best networked car and gave it the "Connected Car of the Year" award.
The concept: the ultimate in prestige and stylish travel
As an addition to the portfolio of S-Class saloons, the Mercedes-Maybach S-Class sets new benchmarks in the luxury segment. The Mercedes-Maybach S-Class melds the perfection of the S-Class with the exclusivity of Maybach. Impressive spaciousness, elegant design and high-quality materials create an ambience of the highest standard, particularly in the rear of the vehicle. Aspects such as premium craftsmanship, extrovert luxury, Maybach excellence, uniqueness and individualisation establish a connection between Mercedes-Maybach and the S-Class. The target group consists of successful businesspeople that will mainly use the Mercedes-Maybach S-Class in a professional context with a chauffeur. For working in the car, technical functions are therefore very important in the back. The majority of customers are from China, Russia and the USA, where high importance is attached to status symbols.
Strictly speaking, the Mercedes-Maybach S-Class has no direct competitors because it is positioned above the existing S-Class segment but below the segment for ultra-luxury vehicles.
The Grand Mercedes: prestigious, high-end motor cars
Size and style combined with technological advances and sublime comfort – these are the shared attributes of prestigious vehicles made by Daimler. Their history dates back to the earliest days of the automobile. As well as conveying passengers in maximum comfort, these luxurious high-end vehicles play an important part in helping their owners to make a dignified impression as befits their status. In terms of style they also always reflect their time. The tradition of prestige vehicles from Mercedes-Benz and the original brands has its roots in the early 20th century and initially went on to 1981 when the final Mercedes-Benz 600 left the factory buildings in Sindelfingen. In 1991 the 600 SEL, the top-of-the-range model in the S-Class 140 model series and at the same time the first Mercedes-Benz production car with a V12 engine, brought the tradition back to life in more than name alone. By 2002, luxury saloons from the Maybach brand were maintaining the connection with power in the high-end segment. In turn the new Mercedes-Maybach S-Class sets another new standard.
1903: the start of a unique tradition
At the beginning of the 20th century, the Mercedes and Benz brands were already shaping the luxury automotive segment and offering customers top-of-the-range models to meet their requirements of comfort and prestige. One early example is the luxurious Mercedes-Simplex 60 hp touring coach from 1904 that Emil Jellinek, father of the brands namesake Mercédès Jellinek, drove on the French Riviera and caused a sensation. The Mercedes-Benz 630 continued this tradition in the 1920s followed by the 770 model known as the Grand Mercedes from 1931. Its era came to a temporary end in 1939. After the second world war the stakes had changed in Germany and Western Europe. People were suffering greater hardship, their needs were existential, their standards more modest. However, Chairman of the Management Board Wilhelm Haspel declared back in December 1947 that: "... what is missing is a vehicle that gold-plates the name Mercedes-Benz again."
1951 comeback: Mercedes-Benz 300 "Adenauer"
The gap was closed in 1951 with the Mercedes-Benz 300. Although nowhere near as ostentatious as the Grand Mercedes of the 1930s, this was the most spacious, comfortable and fastest German saloon of its time and the first prestige vehicle of the post-war period. Facelifted several times, the 300 remained part of the range until 1962 and was the highly prized official car of the German Chancellor. Even today it is referred to as the "Adenauer".
By 1963 the economic miracle was in full swing. Germany was back and this also extended to automotive engineering. The headline of a press release issued by Daimler-Benz AG leaves no doubt: "The Super Mercedes model 600 – the exclusive vehicle for grand luxury." It went on to say that "Mercedes-Benz is creating a link with the companys pre-war tradition of being present in the worlds small group of outstanding prestige vehicles – in the form of a luxuriously appointed car which offers the highest degree of handling safety." The 600 was the first Mercedes-Benz production passenger car with a V8 engine. It set standards in ride comfort and safety worldwide. With a production period of 18 years between 1963 and 1981, the model 600, alongside the SL of the 107 model series, is one of the cars that was made for the longest amount of uninterrupted time at Mercedes-Benz.
Until 2002 the top-of-the-range versions of the S-Class assumed the leading position in the Mercedes-Benz portfolio of cars. The Grand Mercedes then found its natural successor in every respect: luxury vehicles made by the Maybach brand over the next ten years. The first prototype was presented in 1997 at the Tokyo Motor Show under the name "Mercedes-Benz Maybach". It would take 17 years for this combination of names to become a reality, though, in the guise of the 2014 Mercedes-Maybach S-Class. With new highlights from 2014, the Mercedes-Maybach S-Class is steering the unique tradition of prestige vehicles into the future.

2014 Mercedes Benz CLA 45 AMG
Mercedes-AMG kicks off the automotive spring of 2013 in the "Big Apple" in dynamic style as the CLA 45 AMG celebrates its world premiere at the New York International Auto Show. The philosophy behind this four-door mid-series coupé matches that of the successful CLS 63 AMG, the trendsetter among four-door high-performance coupés. A glance at this high-tech package suffices to show that the CLS 45 AMG also has all the typical DNA to make it a perfect representative of the AMGs Driving Performance brand claim: with a peak output of 265 kW (360 hp) and maximum torque of 450 Newton metres, its turbocharged engine is not only the most powerful four-cylinder unit in series production anywhere in the world but also a highly efficient one that meets the EU6 emissions standard. With fuel consumption of 6.9 litres per 100 km according to NEDC combined figures, the CLA 45 AMG meets even the most exacting requirements. The performance-oriented AMG 4MATIC all-wheel drive of the CLA 45 AMG similarly sets a new benchmark in its competitive segment.
Ola Källenius, Chairman of Mercedes-AMG GmbH: "With the CLA 45 AMG, Mercedes-AMG is launching a unique and highly desirable automobile with all the typical DNA of AMG. A high-tech package that includes the most powerful series-production four-cylinder engine in the world as well as performance-oriented AMG 4MATIC all-wheel drive, it embodies Driving Performance at its best."
The new four-door high-performance coupé offers an exceptional combination of an excitingly sporty driving experience, extravagant design and exclusive individuality. With the CLA 45 AMG Mercedes-AMG is establishing a completely new segment – as it did previously with the CLS 63 AMG Shooting Brake (2012) and the CLS 55 AMG (2004). At the time of their launch, neither of these AMG models had any direct rivals, but went on to inspire other automotive manufacturers. Turbocharged engine, all-wheel drive and the AMG SPEEDSHIFT DCT 7-speed sports transmission - the CLA 45 AMG features the same drive system that is already powering the A 45 AMG to deliver highly dynamic and efficient performance.

Typically AMG: the most powerful series-production four-cylinder turbo engine in the world
A glance at the technical data for the CLA 45 AMG shows: the AMG 2.0-litre turbo engine, with a maximum output of 265 kW (360 hp) and up to 450 Newton metres of torque, is the most powerful turbocharged four-cylinder engine in series production anywhere in the world.
The combination of high performance and torque, together with the performance-oriented AMG 4MATIC all-wheel-drive system, gives the CLA 45 AMG driving characteristics almost on a par with those of a sports car. The performance coupé accelerates from zero to 100 km/h in 4.6 seconds and its top speed is 250 km/h (electronically limited). But the AMG 2.0-litre turbo engine is impressive not only in terms of its dynamic performance but also with regard to its efficiency and environmental compatibility. The CLA 45 AMG achieves a fuel consumption level of 6.9 litres per 100 kilometres according to NEDC combined figures, while it already meets the EU6 emissions standard that only comes into effect in 2015 as well as the limit for the particle count per kilometre of 6 × 1011 part./km that will become mandatory in 2017.
The basis for these impressive figures is provided by the high-tech package which has been put together by Mercedes-AMG. As a high-performance engine belonging to the BlueDIRECT family, the four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers. The combination of multiple fuel injection and multiple spark ignition improves fuel utilisation and increases thermodynamic efficiency substantially, leading to lower exhaust emissions. Other highlights include the gravity-die sandcast all-aluminium crankcase, weight-optimised crank assembly with forged steel crankshaft and forged pistons with friction-optimised piston rings, NANOSLIDE cylinder wall technology, air-water charge air cooling, generator management and ECO start/stop function.
Twin-scroll turbochargers and AMG sports exhaust system with exhaust flap
Mercedes-AMG addresses the essential challenges concerning the response of small-displacement turbo engines by means of a twin-scroll turbocharger, maximum derestriction of the exhaust system and an innovative injection strategy. The twin-scroll technology provides for a more spontaneous build-up of charge pressure, making effective use of exhaust gas back pressure, exhaust gas temperature and exhaust gas impulse. This results in a swifter build-up of torque right from the lower rev range. As a positive side-effect, the twin-scroll technology also benefits fuel consumption and exhaust emissions. With a maximum charge pressure of 1.8 bar, the AMG 2.0-litre four-cylinder turbo engine leads the field in this respect, too.
The AMG sports exhaust system features large pipe cross-sections and an automatically controlled exhaust flap. This technology, which is familiar from the SLK 55 AMG, reconciles the two apparently conflicting aims of tangible dynamism and hallmark Mercedes comfort on long journeys. The flap is continuously adjusted by map control according to the power called up by the driver, load status and engine speed. The AMG sports exhaust system emits a fascinating, full engine sound that is particularly impressive during powerful acceleration.
An AMG Performance exhaust system with exhaust flap is available as an option for the A 45 AMG. This provides for an even more emotional and striking engine sound when the throttle is open and during gear shifting. The double-declutching function during downshifting and the interruption of ignition and injection during upshifting under full load produce a particularly throaty sound with the AMG Performance exhaust system and create a level of emotionality which is otherwise the preserve of engines with more than four cylinders.
High-performance cooling system with components from the SLS AMG
The high driving dynamics of the CLA 45 AMG call for a highly effective cooling system. On the basis of the components from the SLS AMG, a low-temperature circuit is additionally deployed for air-water charge air cooling of the four-cylinder turbo engine. The cooler extending across the complete front level of the cooling module is supplemented by an additional cooler in the wheel arch. Together with the charge air cooler, which is connected in series, a high-performance electric pump ensures the required flow through the water coolers located behind the large intake ports. This provides for ideal cooling of the highly compressed charge air, thereby contributing towards optimum engine performance.
The cooling of the transmission oil is integrated into the water cooling circuit for the engine. The water cooler positioned behind the front apron is supported by the heat exchanger which is fitted directly on the transmission and supplied with cooling water as required by means of an auxiliary pump.
"One man, one engine": a tradition of hand-built excellence
As is the case with all eight- and twelve-cylinder engines, the new AMG four-cylinder turbo engine is hand-built according to the traditional AMG philosophy of "one man, one engine". An exclusive assembly line has been set up for the new AMG engine at the Mercedes-Benz engine production plant in Kölleda – where all BlueDIRECT four-cylinder engines are built for the A- and B-Class models. A characteristic feature of the "one man, one engine" production process is the AMG engine plate bearing the signature of the responsible engine fitter. Apart from serving as an AMG hallmark confirming superlative production quality, the AMG engine plate also attests to the peerless DNA of Mercedes-Benzs high-performance brand.
AMG SPEEDSHIFT DCT 7-speed sports transmission
Dual clutch transmission and all-wheel drive – the drive package on board the new CLA 45 AMG is a demonstration of high-end engineering prowess. The AMG SPEEDSHIFT DCT 7-speed sports transmission is directly flange-mounted on the transversely installed engine. Key software modules have been adopted from the SLS AMG super sports car with its inspirational power transmission concept. The dual clutch transmission of the CLA 45 AMG features seven gears, three driving programmes, a double-declutching function and RACE START for optimum acceleration. The strengths of the AMG DCT sports transmission include spontaneous gear shifting without any interruption in tractive power, a tailor-made control strategy, extremely smooth and easy gear shifting and a high level of efficiency. Reinforced gear wheels provide for maximum stability. Synchroniser rings with carbon-fibre friction linings improve durability while also optimising the response time during manual gear-changing – the ideal basis for ambitious laps on cordoned-off race tracks.
"Momentary M mode" for even greater dynamism and driving enjoyment
Another special feature designed to enhance dynamic performance and driving enjoyment is the so-called "Momentary M mode". In C and S mode, this enables the driver to activate manual mode ("M") without having to remove a hand from the steering wheel, by pressing the "up" or "down" shift paddle once. In Momentary M mode the driver experiences the dynamism and performance of gear-shifting in manual mode in all the automatic driving programmes, with automatic up-shifting on meeting the rpm limit into the bargain. This allows the driver to devote his full attention to the vehicles impressive performance.
The shift times in manual mode "M" and in Sport mode "S" are similarly sporty in character to those of the SLS AMG GT super sports car. Briefly and precisely interrupting ignition and injection under full load leads to even faster gearshifts in "M" and "S", with a more emotional sound than ever. In "C" mode (Controlled Efficiency), tangibly soft transmission and engine characteristics support a fuel-efficient and comfort-oriented driving style. In addition, in "C" mode the ECO start/stop function is active.
Performance-oriented AMG 4MATIC all-wheel drive
The CLA 45 AMG comes with variable, performance-oriented AMG 4MATIC all-wheel drive as standard. In developing this all-wheel drive, the focus was firmly on performance and dynamism. The power flux to the rear powertrain is provided by a compact power take-off unit (PTU) which is fully integrated in the 7-speed sports transmission. It does not possess an oil circuit of its own. Instead, it is supplied with lubricant from the oil circuit of the sports transmission. This configuration gives rise to substantial weight advantages in comparison to rival systems which branch off power by means of an add-on component with its own oil circuit. Together with the friction-minimised tapered roller bearings, the PTU achieves an excellent level of efficiency. As an additional bonus, the system weight of the new AMG 4MATIC all-wheel drive is up to 25 percent lighter than the all-wheel-drive versions offered by the competition.
A two-part propeller shaft transfers the power from the AMG 2.0-litre four-cylinder turbo engine to the rear axle. In the interests of favourable weight distribution, an electrohydraulically controlled multiple-disc clutch is integrated with the rear axle differential. The multiple-disc clutch immediately detects slip at the front axle. A hydraulic pump instantaneously presses the discs together and channels the engine torque to the rear wheels as necessary. All this takes place virtually without the driver noticing. To enable particularly fast response, the pump is always active and does not require to be started up each time it is needed, as is customary with other systems. Power distribution is fully variable: in normal driving, the CLA 45 AMG uses front-wheel drive in the interests of optimum efficiency. When the driving dynamics so require, the variable AMG 4MATIC all-wheel drive splits the torque between front and rear axle up to a ratio of 50:50 percent. The variables influencing the power distribution ratio are vehicle speed, lateral and longitudinal acceleration, steering angle, speed difference between the individual wheels, selected gear and accelerator position.
3-stage ESP® with ESP® Curve Dynamic Assist
An exclusive feature is the interaction of the AMG 4MATIC all-wheel drive with the 3-stage ESP® and the ESP® Curve Dynamic Assist. The three ESP® stages enable the driver to vary the dynamics of the CLA 45 AMG according to his individual wishes at the push of a button. The safety-oriented "ESP ON" mode supports the driver in maintaining neutral handling characteristics. The system initiates braking intervention on one or more wheels and reduces the engine torque on detecting that the operating conditions are becoming unstable.
Briefly pressing the ESP® button activates "ESP SPORT Handling" mode. This dynamically oriented driving mode applies appropriate control strategies for later ESP® intervention and increased drive torque at the rear axle. This means more fun at the wheel for drivers who are keen to exploit the vehicles dynamic potential. Pressing the ESP® button longer activates "ESP OFF". In this mode, the ESP® functions are not available. ESP OFF should only be used by experienced drivers on cordoned-off race tracks. If the driver steps on the brake pedal in "SPORT Handling" mode or "ESP OFF" mode, all the safety functions of the ESP® system become available during braking.
ESP® Curve Dynamic Assist complements the ESP® system to perfection: during dynamic cornering, imperceptible braking intervention on the inside wheel gives rise to a defined yaw moment around the vertical axis, resulting in precise cornering by the CLA 45 AMG and ensuring that the vehicle remains under control at all times. ESP® Curve Dynamic Assist is adapted according to the selected ESP® mode. In "ESP SPORT Handling" mode and "ESP OFF" mode it supports the drivers wish for increased agility and driving dynamics. ESP® Curve Dynamic Assist is an additional function of the Electronic Stability Program which noticeably improves not only agility, but also active driving safety in critical conditions.
AMG sports suspension with independent front and rear axle
Like every AMG high-performance automobile, the new CLA 45 AMG also incorporates sophisticated axle technology. For enhanced driving dynamics, the three-link front suspension is provided with stiffer steering knuckles and totally new elastokinematics. Newly developed, more rigid bearings are employed in the lower link plane. These provide for more agile cornering properties and more precise and direct feedback from the road surface. The more rigid bearings also lead to higher camber stiffness, enabling higher cornering speeds. In developing the complete front axle, great importance has been attached to attaining the best possible traction in highly dynamic driving.
The four-link rear axle of the CLA 45 AMG is also a totally new development. In the course of optimising the elastokinematics, the strut bearings were duly adapted for maximum driving dynamics and control. The rear axle carrier is provided with more rigid bearings for increased driving stability; the subframe is rigidly connected to the body. The AMG sports suspension with specifically tuned spring/damper units and larger stabilisers provides for high lateral acceleration and a reduced rolling tendency in fast double bends. The CLA 45 AMG comes as standard with AMG light-alloy wheels fitted with 235/40 R 18 tyres.
AMG speed-sensitive sports steering and AMG high-performance braking system
The electromechanical Dual Pinion AMG speed-sensitive sports steering with AMG-specific, speed-dependent power assistance and a constant steering ratio (14.5 : 1) enables high steering precision and agility. The electric motor is installed in space-saving configuration on the steering gear. The AMG high-performance braking system with ventilated and perforated brake discs all round in size 350 x 32 millimetres at the front and 330 x 22 millimetres at the rear provides for spontaneous and reliable deceleration.
Unmistakable design
Just a glance at the new CLA 45 AMG makes it very clear: any resemblance to the CLS 63 AMG is absolutely intentional. The expressive design idiom of the CLA has been enhanced by Mercedes-AMG with some characteristic AMG elements - and the result is a new design icon. The sporty proportions of the CLA were there from the start , but its dynamic look is reinforced by the AMG "twin blade" radiator grille and the cross strut in the AMG front apron, both painted in matt titanium grey. The generously proportioned cooling air intakes are framed by black flics, which improve the airflow over the cooling modules positioned behind them. Bi-xenon headlamps are included as standard.
An eyecatching view from the side is ensured by the sill panels with inserts in matt titanium grey. Further elements typical of a top-of-the-range AMG model include the AMG twin-spoke light-alloy wheels, painted grey and with a high-sheen finish, plus the "TURBO AMG" lettering on the wing. Seen from the rear, the CLA 45 AMG displays a distinctive AMG rear apron: this not only reveals the presence of the air outlet openings at the sides, but also incorporates a large diffuser insert and a trim section in matt titanium grey. The two chrome-plated twin tailpipes of the AMG sports exhaust system, including an exhaust flap, serve to emphasise the cars dynamic appeal. The striking LED tail lights are a standard feature.
Dynamic, exclusive and top-quality interior
Impressive quality, high-grade materials and all the dynamism and exclusivity commonly associated with Mercedes-AMG - the interior of the CLA 45 AMG leaves nothing to be desired. Sports seats in ARTICO man-made leather/DINAMICA microfibre with red contrasting topstitching, red seat belts, the multifunction steering wheel with shift paddles, the AMG DRIVE UNIT and AMG door sill panels all come as standard. Coordinating perfectly with one another are the brushed aluminium trim of the instrument panel and the five galvanised ventilation outlets. Information is provided by the AMG instrument cluster with its central colour display, the AMG main menu and the RACETIMER.
Numerous individualisation options are available for the CLA 45 AMG (selection):
- AMG carbon-fibre exterior mirror housing
- AMG Exterior Carbon-Fibre package: front splitter, side sill panel inserts and trim on rear apron in genuine carbon fibre
- AMG carbon-fibre interior trim
- AMG Exclusive package

2014 Mercedes Benz CLA 45 AMG US Version
Mercedes-Benz AMG celebrated its world debut of the 2014 model year CLA45 AMG at the New York International Auto Show. Set to go on sale in the U.S. this November, the four-door coupe follows in the design footsteps of the successful CLS63 AMG, the trendsetter for four-door high-performance coupes. With 355 horsepower and torque of 332 lb.-ft., the 2014 CLA45 AMG is the worlds most powerful four-cylinder production engine. The AMG Performance 4MATIC all-wheel drive system on the CLA45 AMG sets new standards in its segment as well.
Ola Källenius, outgoing CEO of Mercedes-AMG GmbH: "In the CLA45 AMG, Mercedes-AMG presents a unique and absolutely desirable automobile with the characteristic AMG genes. The high-tech package with the worlds most powerful four-cylinder production engine and performance-oriented AMG 4MATIC all-wheel drive stands for Driving Performance at its best."
Pure AMG: the most powerful four-cylinder production engine in the world
The 2014 CLA45 AMG two-liter turbo engine is the most powerful turbocharged four-cylinder production engine with 355 hp and 332 lb.-ft. of torque. The combination of high power, strong torque and performance-oriented all-wheel drive lends the CLA45 AMG superb driving performance. The powerful coupe sprints from 0-60 in 4.5 seconds, and top speed is electronically limited to 155 mph. Mercedes-AMG achieves these impressive figures by the use of high-tech engineering throughout the engine and related systems. The combination of multiple injection and multiple spark ignition on each piston stroke improves fuel atomization and substantially increases thermodynamic efficiency, ontributing to low exhaust emissions. Other highlights include a sand-cast aluminum crankcase, weight-optimized crank assembly with forged steel crankshaft and forged pistons with friction-optimized piston rings, NANOSLIDE cylinder lining technology, water-to-air intercooling, alternator management and ECO Start/Stop function.
Twin-scroll turbochargers and AMG sports exhaust system with butterfly valve
Mercedes-AMG addresses the challenge of small-displacement turbo engines by using a twin-scroll turbocharger, minimized restrictions in the exhaust system and an innovative injection strategy. Twin-scroll technology makes effective use of exhaust gas back pressure, temperature and momentum to provide a faster build-up of boost pressure, for a quicker build-up of torque from low revs. Twinscroll technology also benefits gas mileage and exhaust emissions. With boost pressure of 11.9 psi (0.8 bar), the AMG 2.0-liter four-cylinder turbo engine also leads the field with the highest boost pressure used in a production engine.
The AMG Sports Exhaust system features large pipes and an automatically controlled butterfly valve in the exhaust system. This technology (also used in the SLK55 AMG) allows the CLA45 AMG to deliver a distinctive sound on acceleration while also offering a refined note at sustained speed, such as during highway cruising. The valve is continuously adjusted by the engine computer, based on signals about gas pedal position and engine speed.
The exhaust butterfly valve provides a more striking exhaust note when the throttle is open and during shifts. It also produces an especially strong sound during downshifts using the rev-matching feature as well as during upshifts under full load with the momentary suppression of ignition and injection. And, the AMG Performance Exhaust system creates an enhanced exhaust note that is typically reserved for engines with more than four cylinders.
High-performance cooling system with components from the SLS AMG GT
The high power of the CLA45 AMG calls for a highly effective cooling system. Similar to technology in the SLS AMG GT, an extra low-temperature cooling circuit is installed for water-to-air intercooling of the pressurized intake air. A large radiator at the very front of the cooling module is supplemented by a second radiator in the wheel well. A high-performance electric pump provides high flow through the water radiators behind the large air intakes and the intercooler. This provides ideal cooling of the highly compressed intake air, contributing to optimum engine performance.
Cooling of transmission oil is integrated into the engine water cooling circuit. The radiator behind the front fascia is supported by another heat exchanger, which is fitted directly on the transmission and supplied with cooling water by an auxiliary pump.
"One man, one engine": engine production the traditional artisan way
Like all AMG V8 and V12 engines, the new 2.0-liter four-cylinder turbo engine is hand-built according to the traditional AMG philosophy of "one man, one engine" on an exclusive assembly line for the new AMG engine at the Mercedes-Benz engine production plant in Kölleda, Germany. The "one man, one engine" production process is evident in the AMG engine plate bearing the personal signature of the engine builder. The engine plate serves as a symbol of AMGs superlative production quality and underscores the peerless genes of the Mercedes-Benz high-performance brand.
AMG SPEEDSHIFT DCT 7-Speed sports transmission
Dual-clutch transmission and all-wheel drive - the drive train on board the CLA45 AMG is a dramatic demonstration of engineering prowess. The AMG SPEEDSHIFT DCT 7-Speed sports transmission is mounted directly to the transversely installed AMG 2.0-liter four-cylinder turbo engine. The dual clutch transmission of the CLA45 AMG features seven gears, three driving programs, a rev-matching function and RACE START for optimum acceleration. The highlights of the AMG DCT sports transmission include fast shifts without interrupting power, a tailor-made control strategy, extremely smooth and easy gearshifts and a high level of efficiency. Reinforced gears ensure maximum durability, and synchronizer rings with carbon-fiber friction linings improve longevity while also optimizing response during manual gearshifts - the ideal situation for ambitious lap times on a closed circuit.
"Momentary M mode" for even greater dynamics and driving pleasure
Another special feature designed to enhance performance and driving pleasure is the "Momentary M" program. In the C and S shift modes, the driver can activate the “M” manual mode without having to remove a hand from the steering wheel, by simply pressing the "up" or "down" shift paddle once. In "Momentary M" mode, the driver experiences the dynamics and performance in all automatic driving programs, with automatic upshifts only at the rev limit. This allows drivers to devote their full attention to the vehicles impressive performance.
The shift times in manual mode "M" and in sport mode "S" are similar to the SLS AMG GT super sports car. Momentary suppression of ignition and injection under full load leads to even faster gearshifts with a more exciting sound than ever. In "C" mode (Controlled Efficiency), soft transmission and engine characteristics are conducive to a fuel-efficient and comfort-oriented driving style. In addition, the ECO Start/Stop function is active in "C" mode.
AMG Performance 4MATIC all-wheel drive
The development focus for the standard AMG Performance 4MATIC all-wheel drive was on "performance" and "dynamic spirit." A compact power take-off unit (PTU) thats fully integrated into the 7-speed sports transmission transfers power to the rear wheels. Its lubrication is supplied by the same oil circuit as the transmission, resulting in substantial weight advantages compared with rival systems, which use an add-on PTU with a dedicated circuit. Together with low-friction tapered roller bearings, the PTU delivers excellent efficiency. As an additional bonus, the weight of the new AMG 4MATIC all-wheel drive is up to 25 percent less than the systems offered by competitors.
A two-part propeller shaft transfers engine power to the rear wheels. Contributing to favorable weight distribution, a multi-disc clutch is integrated into the rear differential. An electronically controlled hydraulic pump instantaneously presses the discs together and channels engine torque dynamically to the rear wheels when needed. All this takes place virtually unnoticed by the driver. For fast response, the pump is always active and doesnt need to be started each time its needed (as is usually the case with other systems). The torque split is fully variable: in normal driving, the CLA45 AMG is frontwheel drive for optimal efficiency. If the system senses any front wheel slippage, the variable AMG 4MATIC all-wheel drive distributes torque between front and rear wheels at a ratio of up to 50 : 50. The variables influencing the torque split are speed differences between individual wheels, vehicle speed, lateral and longitudinal acceleration, steering angle, selected gear and accelerator position.
3-stage ESP® with ESP® Curve Dynamic Assist
An exclusive feature of the CLA45 AMG is the interaction of the 4MATIC all-wheel drive with the 3-stage ESP® and ESP® Curve Dynamic Assist. The three ESP® stages enable drivers to vary the dynamics of the CLA45 AMG according to their individual preferences at the push of a button. The normal "ESP ON" mode helps the driver maintain safe and neutral handling. The system initiates braking on one or more wheels to neutralize the onset of unstable driving conditions.
Briefly pressing the ESP® button activates a "SPORT Handling" mode, which delays ESP® intervention and allows more torque at the rear wheels. This means more driving fun for those who enjoy using the cars full handling potential. Pressing and holding the ESP® button activates the "ESP OFF" mode, which should only be used by experienced drivers on closed circuits. Whenever a driver steps on the brake pedal in "SPORT Handling" or "ESP OFF" mode, all safety features of the ESP® system are available for the duration of the braking.
ESP® Curve Dynamic Assist complements the ESP® system: during spirited cornering, imperceptible braking on an inside wheel directs more torque to the outside wheel, resulting in precise and safe turnin of the CLA45 AMG. ESP® Curve Dynamic Assist is different in each ESP® mode, and in "SPORT Handling" and "ESP OFF," it helps fulfill the drivers wish for increased agility and driving dynamics. ESP® Curve Dynamic Assist is an extra feature of the already impressive Electronic Stability Program, which noticeably improves not only agility, but also active driving safety, at least within the limits of the laws of physics.
AMG sports suspension with multi-link front and rear axles
Like every high-performance AMG automobile, the CLA45 AMG also incorporates sophisticated suspension technology. For enhanced driving dynamics, its three-link front suspension has stiffer steering knuckles and totally new elastokinematics. Newly developed, more rigid bearings are used in the lower link plane to ensure more agile turn-in as well as more precise and direct feedback from the road. More rigid bearings also lead to better camber stability, allowing higher cornering speeds. In developing the complete front suspension, great importance was placed on maintaining the best possible traction under very sporty driving conditions.
The CLA45 AMG four-link rear suspension is also a totally new development. To optimize elastokinematics, the bushings were modified for maximum driving dynamics and control. The rear suspension carrier is fitted with more rigid bearings for increased directional stability, and the subframe is rigidly bolted to the body. With its tuned spring / shock absorber units and larger stabilizer bars, the AMG sports suspension ensures high lateral acceleration and a reduced body roll in fast S-bends. The CLA45 AMG comes standard with twin-spoke AMG light-alloy wheels inlayed in titanium gray with a high-sheen finish and fitted with 235 / 40 R 18 tires.
AMG speed-sensitive sports steering and AMG high-performance braking system
The electromechanical sports steering with AMG speed-dependent power assist and a constant steering ratio of 15.1:1 provides precise and agile steering. Its electric motor is installed directly on the steering gear to save space.
To provide quick, reliable deceleration, AMG high-performance brakes feature vented and perforated front and rear discs that measure 3.8 x 1.2 inches at the front and 13.0 x 0.8 inches at the rear.
Unmistakable design
Even at first glance, the new CLA45 AMG leaves no doubt about its character; similarities with the CLS63 AMG are intentional. Mercedes-AMG complements the expressive design idiom with distinctive AMG elements, creating a new design standard. The CLA was developed with sporty proportions - the AMG "twin blade" radiator grille and the cross member in the AMG front fascia, both painted matte titanium gray, further reinforce its sporty appearance. Large air inlet ports on the sides are framed by black winglets that improve air flow to the cooling system behind them. Bi-xenon headlights are part of the standard equipment.
From the side of the CLA45 AMG, sill panels with matte titanium gray inserts catch the eye. Other elements of a top-of-the-line AMG model are the twin-spoke AMG light-alloy wheels, inlayed in titanium gray with a high-sheen finish, as well as a "TURBO AMG" badge on the fender. The AMG rear fascia includes stylized side air vents as well as a large diffuser insert and matte titanium gray trim. The conjoined quad-tip chrome tailpipes of the AMG exhaust system emphasize its sporty purpose. Striking LED tail lights come as standard equipment.
Dynamic, exclusive and high-quality interior
Obvious quality, high-end materials and a sporty, exclusive character typical of Mercedes-AMG make the interior of the CLA45 AMG impressive. Standard equipment includes AMG door sill panels, sport seats wrapped in MB-Tex man-made leather and DINAMICA microfibers with red contrasting stitching, red seat belts, a multifunction steering wheel with shift paddles and an AMG DRIVE UNIT bearing the AMG Affalterbach Crest. The AMG instrument cluster provides key information with a central color display, the AMG main menu and the RACETIMER, while brushed aluminum trim on the instrument panel is matched to the five anodized ventilation nozzles.
