Transmission: With wet start-off clutch or torque converter

Sep 26, 2018

Power transmission is handled by the AMG SPEEDSHIFT 9-speed automatic transmission which combines an emotive shifting experience with extremely rapid shift times. In the case of the V8 power units, the wet start-off clutch reduces weight and optimises responsiveness. The transmission of the six-cylinder version features a torque converter.

The AMG SPEEDSHIFT MCT 9G (MCT = Multi-Clutch Transmission) is specially tuned for the requirements of the eight-cylinder variant of the four-door AMG GT. A wet start-off clutch is used here. This saves weight and, as a result of its low inertia, optimises the response to the driver's accelerator pedal input, particularly during acceleration and load changes.

The complex and fine-tuned software ensures extremely rapid shift times as well as quick multiple downshifts where required. Thanks to the double de-clutching function in the "Sport" and "Sport+" drive programs, the system delivers an especially emotive shift experience. Here, defined ignition adjustments enable even faster gearshifts than in the other modes. In all modes, moving off occurs in first gear in order to always guarantee a dynamic driving experience. There is also the RACE START function which ensures optimum acceleration from a standstill.

The inline 6-cylinder engines are coupled with the AMG SPEEDSHIFT TCT 9G (TCT = Torque Converter Transmission) transmission. In conjunction with the torque converter, the automatic transmission is tuned to the special requirements of this engine. On the one hand, this guarantees maximum comfort during pulling away and shifting, while on the other, it allows for AMG-typical rapid and emotive shifting to suit the selected drive program.
