* In addition, the driver immediately experiences a noticeable performance increase thanks to the integrated, electronically controlled limited-slip rear differential: The hybrid model is even more agile when accelerating out of bends, and provides more traction and therefore more driving safety.

* As slip at the rear axle increases, the drive power of the electric motor is also transferred to the front wheels as required for more traction. The mechanical connection of the fully variable all-wheel drive makes this possible by means of a propshaft and the drive shafts of the front wheels.

* The positioning on the rear axle improves the weight as well as the axle load distribution in the vehicle and thus forms the basis for the convincing handling.

* The AMG concept offers very high regeneration efficiency, as the system allows only minimal mechanical and hydraulic losses from the engine and transmission.

* The automated two-speed transmission at the rear axle with its specially calibrated gear ratio ensures the spread from high wheel torque for agile starting to safe continuous output at higher speeds. An electric actuator engages second gear at around 140 km/h at the latest, which corresponds to the electric motor’s maximum speed of around 13,500 rpm.

* With the increase in performance due to the additional electric motor, the development team was also able to improve the efficiency of the entire vehicle in parallel – and achieve lower emissions as well as lower consumption.
