Even when the going gets tough, 4MATIC all-wheel drive helps to keep you more safe on your way. If there is a risk of wheels spinning on surfaces with varying degrees of grip, selective brake actuation instantaneously redirects the engine's torque to the wheels that are not spinning. The electronic dynamic handling control system (4ESPĀ®/4ETS) with integral ABS and ASR contributes even more to the efficiency of the all-wheel drive and also affords excellent traction and directional stability.
