Integrated in an innovative way.
The most innovative components of the new 4MATIC for compact models include the output shaft to the rear axle integrated into the seven-stage automated 7G-DCT dual clutch transmission, and the differential with an integrated, electrohydraulically controlled multi-disc clutch. This enables fully variable drive torque distribution between the front and the rear axle. The performance flow to the rear powertrain is carried out by a compact power take-off unit (PTU), which is fully integrated into the main gearbox and is lubricated via its oil system. Additional benefits of this design are a lower system weight than is available from the competition, and high efficiency. All 4MATIC models are outstanding, as are the front-wheel-drive versions with good energy efficiency.
The 4MATIC all-wheel drive is a completely new development and was designed specifically to coordinate with the new front-wheel drive models.
