The M5's 7-speed SMG Drivelogic system features gear-change keys on the steering wheel and a selection lever on the central console for Formula One-style driving. Gears change within milliseconds, without having to reduce speed, decrease engine power or use a clutch. Special functions such as slip or hill recognition adapt to the gear shift points required by the driving conditions. The Launch Control provides maximum acceleration by ensuring that speed is maintained across the entire range of gear changes.
