The entire vehicle design is testament to the BMW EfficientDynamics philosophy. The optimised, aerodynamic front apron and undercarriage feature innovative improvements that reduce air resistance and fuel consumption.
The front apron is a prominent design feature that embodies the BMW EfficientDynamics philosophy. The integrated Air Curtain channels air through two vertical air inlets and along the front wheel arches. The accelerated air flow creates a kind of "curtain" on the outer side of the wheels. Then there is the Air Breather, which channel the air flow at the front wheels. These innovative technologies reduce turbulence and air resistance, which in turn significantly reduces fuel consumption.
The flat undercarriage cover, which also shields the engine compartment, is an additional detail that greatly improves the car’s aerodynamics. This new trim elements are not only highly advantageous in terms of aerodynamics: they also improve sound insulation and provide greater protection from rust.
