In “ESP OFF” mode, another innovation allows the driver to exert even more influence on the handling characteristics of the AMG GT R. The new AMG TRACTION CONTROL system also comes directly from motorsport. It allows drivers to pre-select the slip on the driven rear axle in nine levels. Just like in the current AMG GT3, it isolates the grip on the driven wheels and does not affect the stabilisation provided by the ESP®. Corresponding characteristic maps are programmed into the vehicle electronics to this end.
Control is via a special rotary switch located in the centre console below the ventilation outlets. Depending on the setting, the system permits more or less slip on the rear wheels - very helpful in varying road conditions.
A special engineering feat is the completely new active aerodynamics profile, which is concealed almost invisibly in the underbody in front of the engine. At a speed of 80 km/h in "RACE" mode, and at 120 km/h in "Comfort", "Sport" and "Sport Plus" modes, this carbon fibre element, which only weighs around two kilograms, automatically moves approximately 40 millimetres down. This process involves considerable change in the airflow and results in what is known as the Venturi effect, which additionally "sucks" the car onto the road and reduces the front-axle lift by around 40 kilograms at 250 km/h. If the AMG GT R in "RACE" mode drives more slowly than 60 km/h or in "Comfort“, "Sport" and "Sport Plus" modes more slowly than 80 km/h, the element moves back in.
