The AMG SPEEDSHIFT MCT nine-speed sports transmission is specially tuned to requirements in the new E 63 S 4MATIC+. This involved re-engineering hardware and software alike.
A special software development enables extremely short shift times, fast multiple downshifts and the double-clutching function, making for a highly emotive gearshifting experience. A wet start-off clutch replaces the torque converter. This saves weight and optimises the response time to the driver’s accelerator pedal input, particularly when accelerating and during load changes.
