The eight-speed Steptronic transmission with Drivelogic sets new benchmarks in dynamics and gear changes. The unusually fine increments between gears and the extremely rapid changes facilitate optimum force delivery at all speeds, guaranteeing the ultimate in power and efficiency. Particularly at high speeds, the eighth gear reduces the engine speed, in turn decreasing both fuel consumption and engine noise. The driver can change gear manually in "D" mode as well as in "S" mode, via the M gear lever or the M gearshift paddles on the steering wheel. In manual "S" mode, the M Steptronic transmission does not automatically shift up and the engine reaches max speeds when necessary.
Additionally, the driver can change gear very dynamically at top speeds and use the Drivelogic function to set the shifting behaviour to one of three choices: comfortable and efficient, dynamic or racetrack dynamics with extra-short gear change times. A torque converter clutch ensures a direct connection between the engine and the transmission, with minimal loss of power. An M-exclusive feature: when the vehicle is at a standstill, there is no automatic force-transmitting connection between the engine and the transmission, which prevents "creeping". However, while manoeuvring, for example, a short tap of the accelerator activates "creeping on demand".
