Brabus released details of its new B63S tuning program for the Mercedes CLS63 AMG, both sedan and shooting brake – normal or S-Model. They will make their debut at the Geneva Motor Show next up to the 800-hp Brabus SL65.
This package is not as powerful as the 800 program, but still, not what you call a slouch. The 5.5 liter M157 twin-turbo V8 engine is tuned up to 730 horsepower and over a 1000Nm of torque, which means 0 to 100 km/h takes 3.7 or 3.8 seconds – depending on the model.
As for the top speed, the shooting brake is limited to 300 km/h, but the sedan can reach 350 km/h – the same as the new McLaren P1 hyper car.
Some of the technical changes Brabus applies to get this kind of power out of the AMG engine include a bespoke exhaust system, upgraded air intake package, remapped ECU, tweaked turbochargers with big intercoolers, and high performance catalysts. They also fit the car with a limited slip differential to help it put the power down.
The package also includes an aerodynamic body kit with discreetly designed but functional front and rear spoilers, side skirts, and diffusers, plus 19 and 20-inch wheels. There is also some interior upgrades, such as leather and Alcantara upholstery package, carbon fiber trims, and the ever popular Brabus illuminated side sills.
