Did you just purchase the 2015 Mercedes-Benz S63 AMG 4Matic Coupe and it’s just not quick enough? Yes, your new luxury sports coupe has a 5.5L twin-turbo V8 with 577 horsepower that is good for 3.9 second 0-60 MPH sprints. You could step up to the S65 AMG Coupe, but that biturbo V12 beast only comes in rear-wheel-drive, and thus can only muster a 4.0 second acceleration to 60 MPH.
Don’t worry, Brabus has you covered with the 850 6.0 BiTurbo. This longtime Mercedes tuner increases the displacement of the V8 to 5,912 cc and installs their own set of turbos and ECU programming. They also do a lot of work on engine component machining and polishing to improve flow. Brabus also supplies a new exhaust system and customized interior. The 7-speed automatic transmission and the 4Matic all-wheel-drive systems carry over from the AMG car.
The result is a 850 horsepower @ 5,400 rpm and the torque is a mind-boggling 1,069 lb-ft @ 2,500 – 4,500 rpm. If you think that over a thousand foot-pounds of torque is too much, Brabus is surprisingly with you. They electronically limit the torque to 848 lb-ft to try to save the transmission and the 4Matic systems.
The 850 6.0 BiTurbo is capable of 3.5 seconds 0-60 MPH acceleration and the top speed is electronically limited to 217 MPH in order to save the tires. After all, you don’t want your tires to come apart above 217 miles per hour, right?
Brabus is using gold as a heat shield on some of the engine-bay components. Hence, the gold trim on the interior as well.
What does the Brabus 850 6.0 BiTurbo compete with? There are several other crazy tuners, but there is another factory-approved coupe that could give the Brabus a fair drag race. It’s the 2015 BMW Alpina B6 Gran Coupe. The Alpina has been turned up to 600 horsepower for the 2015 model year.
TFLcar has never tested a Brabus, but the Alpina B6 has thoroughly impressed us.
Also, watch this drag race between the Alpina B6 and Chevy Corvette C7.
