Winter's harshest days can bring snow-covered roads and patches of black ice. 4MATIC employs the 4-wheel Electronic Traction System (4-ETS), monitoring each wheel for slippage and individually braking wheels to maintain the balance of power. By ensuring that power is transferred to the wheels with grip, 4MATIC will keep you going, even if only one wheel has traction.
After the rain, mud can cause tires to slip. 4MATIC consists of a transfer case that feeds power to the front and/or rear axles. The 4-wheel Electronic Traction System (4-ETS) uses the vehicle's Antilock Braking System (ABS) and Electronic Stability Program (ESP®) sensors to precisely manage each wheel. This seamless integration creates predictable handling on unpredictable surfaces.
Pools of water at the edge of the road can be treacherous. 4MATIC dispenses with conventional differential locks. Instead, wheels with insufficient grip are braked automatically, while torque is increased at the wheels with good traction. These fast, automatic braking pulses achieve the same effect as three differential locks. Providing effective control in uncontrollable climates.
