BMW 5 Series: 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.
