BMW 3: Coasting
Concept
Under certain conditions the engine is automatically decoupled from the transmission in the D selector lever position. The vehicle continues traveling with the engine idling to reduce consumption.
Selector lever position D remains engaged.
This driving condition is referred to as coasting.
As soon as you step on the brake or accelerator pedal, the engine is automatically coupled again.
General information
Coasting is a component of the ECO PRO driving mode.
Coasting is automatically activated when ECO PRO mode is called via the Driving Dynamics Control.
A proactive driving style helps the driver to use the function often and supports the efficient effect of coasting.
