To improve traction and vehicle dynamics, the E 63 S 4MATIC+ has an electronically controlled rear differential lock. This reduces the slip on the inside wheel when cornering, without control interventions in the braking system. This ensures that the driver is able to accelerate out of corners earlier and with more power thanks to the improved traction. The greatest benefit of the electronic rear-axle limited-slip differential is the even more sensitive and proactive control, which pushes the thresholds higher and makes it even easier to drive at the vehicle’s limits.
