625 kW / 850 hp (838 bhp) of power and 1,450 Nm (1,069 lb-ft) of torque in the wagon: The BRABUS 850 6.0 Biturbo based on the Mercedes E 63 AMG celebrates its world premiere at the 2013 ESSEN MOTOR SHOW and in tandem with the BRABUS version of the CLS 63 AMG Shooting Brake becomes the world’s most powerful street-legal all-wheel-drive wagon. 

Powered by the most powerful BRABUS engine to date, the new 850 6.0 Biturbo V8 high-capacity engine, the five-door supercar delivers superlative dynamics: As a 4MATIC all-wheel-drive model the wagon from BRABUS sprints to 100 km/h (62 mph) in just 3.1 seconds. Top speed is limited electronically to 300 km/h (186 mph) to protect the tires.

The BRABUS 850 6.0 Biturbo, which is of course also available as a sedan, impresses not only with superior performance, but also with its sporty-elegant BRABUS aerodynamic-enhancement kit, tailor-made BRABUS Monoblock wheels with diameters of 19 or 20 inches, and its BRABUS fine leather interior tailored to the individual customer’s preferences.

The turbocharged eight-cylinder engine in the AMG E 63 serves as the perfect basis for professional engine tuning. BRABUS relies on the tried and proven concept of increasing displacement for the new top-of-the-line engine. To increase the displacement of the four-valve engine from standard 5,461 cc to 5,912 cc (333 to 361 cubic in.) the BRABUS high-tech engine-building shop increases cylinder bore to 99 millimeters (3.89 in.) and installs forged pistons tailor-made to the new specs. A precision-balanced billet custom crankshaft with a stroke of 96 instead of the standard 90.5 millimeters (3.77 instead of 3.52 in.) in conjunction with eight custom billet piston rods completes the displacement increase. In addition, both cylinder heads are optimized for improved mixture flow.

Additional performance potential lies in the engine peripherals: The production turbos are replaced by two BRABUS turbos with a larger compressor unit and special exhaust manifolds. To optimize the air supply, the BRABUS engine specialists designed the carbon-fiber BRABUS 850 intake module, which includes a larger air filter box with enlarged intake cross section. For an optimal supply of fresh air the hood has an integrated air duct, which draws cool air via generously dimensioned air tube from an aperture in the front fascia to optimize power yield of the engine.

To lower the charge-air temperature and thus positively influence power delivery, BRABUS fits the intake and charge-air tubes with special "Gold Heat Reflection" sheathing.

The discharge of exhaust gases is optimized with high-performance catalysts and a BRABUS stainless-steel sport exhaust with controlled butterfly valve. The driver can choose between a throaty V8 exhaust note in “Sport” mode and a subtle whisper in “Coming Home” mode at the push of a button. The two ceramic-coated design tailpipes with cast BRABUS logo on either side of the BRABUS diffuser make the exhaust system also a visual treat. 

The perfect coordination of all high-performance components is ensured by means of special mapping for the electronic engine management system. This creates an optimal symbiosis of maximum performance, perfect drivability and eco-friendly emissions complying with strict EURO VI emissions standards. The high-tech lubricants for the entire powertrain are supplied by technology partner MOTUL.

The new high-capacity engine is the most powerful BRABUS to date: The rated power output of 625 kW / 850 hp (838 bhp) at a low 5,400 rpm and the enormous peak torque of 1,450 Nm (1,069 lb-ft) between 2,500 and 4,500 rpm are new benchmarks for high-performance automobiles based on Mercedes-Benz. In the vehicle peak torque is electronically limited to 1,150 Nm (848 lb-ft) in the interest of the longevity of the powertrain. Of course this high-performance engine is also backed by the one-of-a-kind BRABUS Tuning Warranty of three years, up to 100,000 kilometers/62,000 miles (see BRABUS Warranty Terms and Conditions, updated July 2013).

The BRABUS 850 6.0 Biturbo high-performance engine can be installed in a rear-wheel-drive or 4MATIC all-wheel-drive E 63. Due to the better traction the four-wheel-drive version in particular delivers acceleration figures only attained by a very few super sports cars or super sports bikes: From rest the wagon reaches a speed of 100 km/h (62 mph) in just 3.1 seconds. Due to the tires the top speed of the wagon has to be limited to 300 km/h (186 mph). The lower rear-axle load of the sedan allows a top speed of up to 350 km/h (217 mph) with high-performance tires, depending on the final-drive ratio and the programming of the BRABUS Vmax unit.

BRABUS also offers three other power levels without a displacement increase for the current E 63 AMG models. They range from 456 kW / 620 hp (611 bhp) and 478 kW / 650 hp (640 bhp) to 537 kW / 730 hp (720 bhp) in the BRABUS B63S-730 version.

To further optimize handling stability, the BRABUS designers developed lightweight, high-strength carbon-fiber bodywork components in the wind tunnel. 

The front spoiler lip, which attaches to the production bumper of the E 63 and also fits the sedan, reduces negative lift on the front axle at high speeds while lending the vehicle an even more distinctive nose. The BRABUS diffuser insert provides the perfect backdrop for the two dual tailpipes of the BRABUS sport exhaust. 

BRABUS offers tailor-made tire/wheel combinations for the E 63 AMG that match the designer outfit. The largest version features one-piece BRABUS Monoblock F or R wheels in size 9.5Jx20 with tires in size 255/30 ZR 20 on the front axle and size 295/25 ZR 20 tires in the rear. There is also a version that features BRABUS Monobock R "Platinum Edition" forged wheels in sizes 9Jx20 in front and 10.5Jx20 at the rear. The matching high-performance tires are supplied by BRABUS technology partners Continental, Pirelli and YOKOHAMA. 

The company upholstery shop crafts BRABUS fine leather interiors from especially soft and breathable BRABUS Mastik leather and Alcantara in any desired color to customer specifications. 

Particularly ergonomic BRABUS aluminum shift paddles and BRABUS RACE pedals add sporty highlights.

The BRABUS 850 6.0 Biturbo can be ordered as a complete car. Alternatively BRABUS will convert any current Mercedes E 63 AMG completely or in stages to this level.
