Brabus unveiled the Brabus 850 6.0 Biturbo Coupe at its first world premiere for the 2015 Geneva Motor Show. With 850 horsepower and a peak torque of 1,450 Nm, the Biturbo Coupe has a 0-62 time of 3.5 seconds, electronically-limited to 350 km/h (217 mph), making it the world’s fastest and most powerful all-wheel drive coupe. The two-door car’s design is based off the Mercedes-Benz S63 AMG 4MATIC and utilizes the same eight-cylinder twin-turbo engine but with special metal catalysts and a stainless steel sports exhaust system with an actively controlled butterfly valve. Power is leveled at all four wheels with the 4MATIC all-wheel-drive system and seven-speed automatic transmission. The model features clear-coated carbon fiber aerodynamic enhancement components and 21-inch forged high-performance tires, plus a large air filter housing and new carbon fiber air ducts with enlarged cross-sections which are housed under the hood. The exterior contains aluminum components, such as the paddle shifters, pedals and door pins, and is finished off with black paint. The interior features fine black Mastik leather with contrasting copper-colored seams and piping. Overall, the Brabus 850 6.0 Biturbo Coupe boasts sporty design, elegant finishing and unrivaled performance. Check out the photos above.
