BMW 5 Series: Active air flap control

BMW 5 Series G30 2016-2026 Training Manual / Powertrain / Cooling / Active air flap control

It was possible to carry over the active air-flap control from the G12. The cooling surfaces at the front of the vehicle can be closed by means of two separate air flaps. This reduces the drag coefficient and thus saves fuel. A further advantage is faster heating up of the engine after a cold start.
