Intelligence is the most efficient power unit.

The Auto Start Stop function automatically switches off the engine when the car is at a standstill and the clutch is not operated and starts it again as soon as the clutch is operated. Fitted for example in all BMW 1 Series models with a four-cylinder engine and manual transmission, the Auto Start Stop function helps reduce both fuel consumption and emissions.
