4Matic (stylized as 4MATIC) is the marketing name of an AWD four-wheel drive system developed by Mercedes-Benz. It is designed to increase traction in slippery conditions.
The first generation 4Matic system was originally a complex electronically controlled system with automatically engaging four-wheel drive (4WD), the system employs locking central and rear differentials to provide additional traction in slippery conditions.ome newer versions of 4Matic are true AWD as the system remains active at all times. Sophisticated engine management and ABS systems control the amount of torque transferred to each wheel allowing the system to be effective at any speed.
