Support for the combustion engine (boost)
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
During strong acceleration, for example overtaking operations, power output is called up from the electrical machine in addition to that from the combustion engine. This means that maximum power output is available. The accelerator pedal has to be pressed down firmly (kick-down). The revolution counter shows the current engine speed. At the same time, all 4 arrows on the left-hand side light up. The boost function can be used up to a driving speed of 160 km/h.
