Automatically controlled all-wheel drive (4MATIC), general
The automatically controlled all-wheel drive (4MATIC) is a permanent all-wheel drive with central differential.
Integration of the transfer case in the A/T reduces the teeth engagement and realizes an optimized lubrication concept.
The base blocking torque of 50 Nm serves to improve traction at low engine torque and serves to prevent drivetrain vibrations.
The fixed drive torque distribution is 45% at the front axle and 55% at the rear axle.
The drive torque is distributed via a single-speed transfer case without off-road ratio to the drive axles (drivetrain).
Further subfunctions are described separately in:
- Transfer case, 4MATIC function
- Side output, 4MATIC function
- Front axle transmission, 4MATIC function
- Oil supply for transfer case, 4MATIC function
- Electronic traction system, 4MATIC function
- Downhill Speed Regulation, function (on model 204.9 with code (430) Off-Road Engineering package)
- Off-road transmission mode, function (on model 204.9 with code (430) Off-Road Engineering package)
