Rear-axle limited-slip differential: optimal traction, including on the race track
For improved traction and vehicle dynamics, the C 63 Coupé is provided with a mechanical rear-axle limited-slip differential, while the C 63 S Coupé comes with an electronic rear-axle limited-slip differential. Both differentials reduce the slip on the inside wheel when cornering, without control interventions in the braking system. This allows the driver to accelerate out of corners earlier thanks to the improved traction. The car remains more stable when braking from high speeds, and the limited-slip differential also improves traction when moving off. The model-specific, completely redesigned rear axle was specially adapted to the higher vehicle dynamics of the Coupé.
The greatest benefit of the electronic rear-axle limited-slip differential - installed as standard on the C 63 S - is the even more sensitive and faster control, which further raises the critical limit of driveability. The 3-stage ESP® with "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF" settings works in perfect unison with the rear-axle limited-slip differential and is optimally tuned to the outstanding dynamics.
Traction control using electronically controlled limited-slip differentials (ELSDs) may be applied at the driven wheels so that the vehicle can maintain longitudinal motion by sending more traction torque to the higher friction wheel.
