The innovative design of the vehicle is systematically geared to the BMW EfficientDynamics philosophy. In particular, the aerodynamically optimised front apron and the underbody impress with their innovative new features that reduce drag and fuel consumption.
Embodying the BMW EfficientDynamics philosophy in a visible design feature is the front apron. The integrated Air Curtain guides the airstream along the front wheel housings via two vertical inlets. Once accelerated, the stream of air then forms a "curtain" around the outer sides of the wheels. These innovations reduce turbulence and drag, thus lowering fuel consumption.
The smooth underbody lining and the engine compartment screening are further details that enable a significant enhancement in aerodynamics. The new lining features not only bring a considerable gain in terms of aerodynamics, they also provide improved acoustic insulation and increased corrosion protection as practical benefits.
