BRABUS 850 6.0 Biturbo In The E-Class
850 horsepower, 1450 Nm of torque, a top speed in excess of 350 km/h: these are the unique performance figures of the BRABUS 850 6.0 Biturbo that comes to the starting line as the legitimate successor of the famed BRABUS 800 E V12.
For almost two decades the four generations of the BRABUS E V12 ruled the segment of the superfast sedans. What once started with the implantation of a BRABUS 6.9 V12 increased-displacement engine producing 509 horsepower into the body of a Mercedes 500 E of the W 124 model series, and culminated in the BRABUS E V12 “one of ten” super car with 800 horsepower of power and a top speed in excess of 370 km/h presented at the 2009 IAA, now finds its even more powerful continuation.
The BRABUS 850 6.0 Biturbo, based on the current Mercedes E 63, uses eight instead of twelve cylinders. To this end the motor engineers from BRABUS developed a new high-performance engine with an increased displacement of six liters (361 cu. in.).
Like its predecessors, the BRABUS 850 6.0 Biturbo, which of course is also available as a wagon, comes with an efficient BRABUS aerodynamic-enhancement kit, tailor-made BRABUS Monoblock wheels and an exclusive BRABUS fine leather interior.
The eight-cylinder engine of the E 63 and its two turbochargers provide the perfect breeding ground for an enormous power boost. To this end the BRABUS motor engineers developed a displacement increase from standard 5,461 cc to 5,912 cc. Simply increasing the bore of the eight cylinders in the BRABUS high-tech engine-building shop to 99 millimeters would be insufficient. The precision-balanced billet crankshaft with a stroke of 96 mm instead of the standard 90.5 millimeters in concert with special forged billet pistons and billet piston rods completes the displacement increase. In addition, both cylinder heads are optimized for mixture flow.
The turbocharging system of the eight-cylinder four-valve engine was upgraded accordingly: the air intake system and the two BRABUS turbochargers with larger compressor unit and special manifold were all developed from the ground up. The BRABUS 850 intake module with an air filter box with larger cross section was developed to supply the adequate amount of air. An air duct integrated into the hood is also part of this special intake manifold as is the larger intake pipe, which is positioned directly exposed to the relative wind in the front bumper to provide air to the engine.
Low charge-air temperatures are beneficial to power yield and engine temperatures, and consequently BRABUS equips this engine with intake and charge-air pipes wrapped with special and immediately identifiable “Gold Heat Reflection” sheathing.
Free-flow metal catalysts and a BRABUS high-performance exhaust system with controlled butterfly valve are installed on the exhaust side. This includes active control of the exhaust note from the driver’s seat. At the push of a button drivers can choose between a quiet “Coming Home” mode and an earthy, full-blooded V8 sound when the “Sport” position is selected. With its dual ceramic-coated design tailpipes on either side with cast BRABUS logo this exhaust system is also a visual treat.
The BRABUS electronics engineers used their immense know-how and state-of-the-art engine test rigs to recalibrate the engine management system to ensure the perfect interaction of all high-performance components and consequently an optimal power output. The result is not only tremendous performance, but also compliance with stringent EURO VI emissions standards. The high-tech lubricants for the entire powertrain are supplied by technology partner MOTUL.
The performance data of the BRABUS 850 6.0 Biturbo increased-displacement engine speak volumes: 850 horsepower at a low 5,400 rpm are just as unique for a street-legal sedan as is a constant torque of 1,450 Nm between 2,500 and 4,500 rpm. In the car this figure is limited to 1,150 Nm to reduce stress on the entire drivetrain. 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).
In conjunction with the modified SPEEDSHIFT MCT 7-speed sports transmission the new engine lifts all versions of the E 63 to a performance level previously virtually inconceivable for a sedan or a wagon. With rear-wheel drive the BRABUS 850 6.0 Biturbo sprints from rest to 100 km/h (62 mph) in just 3.7 seconds. With 4MATIC all-wheel drive and the added traction it provides this exercise actually takes only 3.1 seconds. Depending on the tires, the final drive ratio and the programming of the BRABUS Vmax unit, the top speed ranges between 300 km/h (186 mph) and more than 350 km/h.
In addition, BRABUS offers three more performance stages for all current E 63 variants that do without a displacement increase. Their power outputs range from 620 horsepower and 650 horsepower to 730 horsepower for the BRABUS B63S-730 version.
Favorable aerodynamic properties are essential for perfect handling stability at the tremendous speeds attained by such powerful vehicles. The BRABUS designers went into the wind tunnel to develop bodywork components made from extremely lightweight yet ultra-strong carbon fiber.
The front spoiler lip attaches to the underside of the production bumper of the E 63. Its shape reduces negative lift on the front axle of sedan and wagon.
Also made from this superlight composite material are the BRABUS rear separation edge and the diffuser insert, which provides the perfect backdrop for the two dual tailpipes of the BRABUS sport exhaust.
The immense top speed of the BRABUS 850 6.0 Biturbo requires special high-performance tires. The largest version features one-piece BRABUS Monoblock F or R wheels of size 9.5Jx20 with high-speed-capable tires of sizes 255/30 ZR 20 on the front axle and 295/25 ZR 20 tires in back. There is also a version featuring BRABUS Monoblock R “Platinum Edition” forged wheels of size 9Jx20 in front and size 10.5Jx20 on the rear axle.
The BRABUS fine leather interior, which is handcrafted meticulously by the experienced upholsterers of the automotive refinement specialist, can be ordered in any desired color. BRABUS aluminum shift paddles with a highly ergonomic design and BRABUS RACE pedals add a markedly sporty note.
The BRABUS 850 6.0 Biturbo can be ordered as a complete car or BRABUS can convert any existing current Mercedes E 63 entirely or step by step to this specification.
