With 9 gears and double-declutching function, this transmission allows extremely dynamic acceleration and ultra-short shift times as well as a fuel-saving driving style. The systematic further development of hardware and software has made it possible to further optimise the reaction times. This means that the driver's shift commands can be carried out faster than ever before. Gear changes are performed with no interruption in tractive power. Ultra-fast, responsive multiple downshifts are another forte of the AMG SPEEDSHIFT 9G-TRONIC. The driver can change via kickdown directly from 9th into 6th or from 5th into 2nd gear, for example.
