Brabus turns the ferocious Mercedes E63 AMG into a 850-horsepower Biturbo Monster

Brabus is a German tuning company that specializes in taking already fast Mercs and making them ridiculous. Brabus is the opposite of subtle, an antonym for modesty. 

The company’s first contract dates back to 1984, where founder Bodo Buschmann modified a fleet of 200 Mercedes 190Es with aftermarket parts. Since then, Brabus has only gotten crazier.

The highlights include an 800 horsepower S600 luxury sedan, a 720 hp, CLS-based “Bullit”, and a 455 hp G500 SUV. They even made a tricked-out Smart Fortwo. According to a report by In Auto News, Brabus raised the bar even further with a tuned version of the Mercedes E63 AMG.

Dubbed the 850 6.0 Biturbo, this Brabus maniac churns out – you guessed it – 850 ponies from its twin-turbo 6.0-liter V8. For reference, the standard E63 AMG has just a 5.5-liter V8 with 550 hp. A drowsy sloth by comparison.

The extra power comes from a new crankshaft, increased engine displacement, larger turbos, and forged piston rods. A 7-speed Multi Clutch Technology (MCT) transmission helps the rear-wheel-drive car rocket from 0 to 60 in 3.7 seconds.

Brabus also offers a 4MATIC all-wheel-drive version, which cuts that time down to 3.1 seconds. Given the right road, this car can reach 217 mph.

Other additions include a high-flowing exhaust, which has butterfly valves that allow you to customize the engine note. Want a muted, more civilized sound? Select “Coming Home” mode. Want to set off some car alarms? Simply press the  “Sport” button and let the V8 sing.

While the performance of the Biturbo borders on insanity, the interior looks comfortable, plush, but still aggressive. Quilted leather upholsters the seats, and accents like aluminum shift paddles and Brabus race pedals ornament the cabin. 

The price? As they say, if you have to ask, you probably can’t afford it. The 850 6.0 Biturbo can be ordered as a whole car for just over $405,000. Or, Brabus can modify your car for you, taking the already-menacing E63 AMG and turning it into a Biturbo monster.
