Every BMW has BMW EfficientDynamics technology as standard. As an intelligent form of energy management, this allows sustainable mobility. The aerodynamically-optimised car design achieves impressive effects for greater dynamism and efficiency.
The BMW engineers can leverage the outstanding infrastructure of the BMW Group Research and Innovation Centre (FIZ) in Munich – one of the largest wind tunnels in the world – and huge computer capacity, with 10,000 processors. The results are impressive: the BMW i8, for example, boasts a drag coefficient (Cd value) of 0.26. In theory, a Cd value of 0.20 is pushing the limits of what is possible for a car that can actually be used.
Values like this are the result of many detailed aerodynamic solutions, which have a positive effect on efficiency, reducing consumption, and ride stability, as well as reducing noise levels inside the car. These solutions include the active rear spoiler, the Air Blade on the C pillar, and the air breather behind the front wheels.
