The entire vehicle design is testament to the BMW EfficientDynamics philosophy, to minimise fuel consumption and CO₂ emissions while increasing dynamics and driving pleasure . The optimised, aerodynamic front apron and undercarriage feature details that reduce air resistance and fuel consumption.
Consisting of the Aero Curtain and Air Breather, the front apron is a prominent feature that embodies the BMW EfficientDynamics philosophy.
By channeling air through two vertical air inlets and along the front wheel arches, the integrated Aero Curtain accelerates airflow to reduce turbulence on the outer side of the wheels, as do the Air Breather channels. Reducing turbulence reduces drag, which in turn reduces fuel consumption.
By continuously assessing the cooling needs of the engine, and opening or closing the radiator air vents in response Air Vent Control optimises the aerodynamics and shortens the engine’s warm-up phase. Both mean reduced fuel consumption.
