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’s the Air Breather, which channels the air flow at the front wheels. These innovative technologies reduce turbulence and air resistance, which in turn reduces fuel consumption.
The automatic air vent control uses a sensor to continuously assess the current cooling needs of the engine and opens or closes the radiator air vents in response. This optimises aerodynamics and shortens the warm-up phase for reduced fuel consumption.
The rear spoiler at the roof edge and the Air Blades joined to it at the sides go together to form a highly efficient so-called "trailing edge". The precisely defined air flow at the rear reduces disruptive air swirl and the braking effect of negative pressure to a minimum.
