What does Mercedes-Benz's 4matic mean?

[RuthFitz]

Mercedes-Benz's 4Matic refers to the all-four-wheel drive system, with the core technology being the 4ETS differential limiting technology. 4ETS utilizes the automatic braking force distribution function of ABS to achieve differential limiting. The development of Mercedes-Benz's 4Matic all-four-wheel drive system: The first-generation 4MATIC used lockable center and rear axle differentials, where the center differential contained two sets of clutches, each independently controlled to achieve various driving modes. The current Mercedes-Benz 4MATIC employs open differentials at the front, center, and rear. The center and rear differentials feature a lockable multi-plate clutch structure, functionally serving the role of traditional differential locks. With the assistance of four-channel ABS, torque can be distributed to each wheel, maximizing driving safety and enabling powerful off-road capabilities. Characteristics of Mercedes-Benz's 4Matic all-four-wheel drive system: The 4Matic system is designed to be compact and lightweight while offering optimized friction performance, providing significant advantages over other all-four-wheel drive systems. It also improves in weight, fuel economy, comfort, and passive safety.
