The BRABUS engine specialists have developed the B63 S performance kit specifically for the fast-revving engine of the Mercedes C 63 AMG. By adding free-flow catalytic converters, high-flow air filters and tweaking the ECU with new ignition and injection maps, Brabus bumps the 6.2-liter V8 from 457 HP to 530 HP, sends torque from 442 to 479 lb-ft and gives you enough to propel the newly tuned beast to a top speed of 197 MPH. Even more power for all Mercedes 63 AMG models: BRABUS presents its B63 S engine tuning, which boosts power output of the high-revving 6.2-liter V8 to 550 hp / 404 kW and peak torque to 650 Nm. With a sprint time from rest to 100 km/h of just 4.3 seconds and a top speed of 330 km/h a CLS 63 AMG with B63 S tuning turns in performance worthy of a true super sports car.
