A key feature of the system is the new 7G-DCT dual clutch transmission with integrated power take-off unit (PTU), which transfers drive torque to the rear axle. The redesigned rear axle gear unit, which realizes fully-variable distribution of drive torque between the front and rear axles in real time, is also explained. Captivating simulations demonstrate the operating principle of the new 4MATIC system and are interspersed with scenes from Development, Trial Testing, and Manufacturing.
