The extremely high torque of the S 65 Cabriolet is transferred by the tried and trusted AMG SPEEDSHIFT TCT 7G transmission. It delivers convincing tailor-made dynamics and high variability. Whether automatic or initiated by the driver using the steering wheel paddle shifters, upshifts or downshifts are affected quickly and instantly. Especially in the "Sport+" and in manual driving modes, the transmission is very fast and responsive.

For the first time the S 63 4MATIC+ Cabriolet have been fitted with the AMG SPEEDSHIFT MCT 9G transmission, which convinces with extremely short shift times, lightning reactions to shift paddle commands, a double-clutching function and fast multiple downshifts. A wet start-off clutch replaces the torque converter of the production model. This saves weight and improves the response to the driver's accelerator pedal input, particularly during acceleration and load changes. It also allows the RACE START function.
