Aerodynamics.

With the airstream on your side. The innovative design of the BMW 1 Series Convertible consistently adheres to the BMW EfficientDynamics philosophy and selectively channels the airstream in order to reduce drag and hence fuel consumption.

The aerodynamically optimised front apron of the BMW 1 Series Convertible embodies the BMW EfficientDynamics philosophy as a visible design feature. The integrated Aero wheel housing guides the airstream along the front wheel housings via two vertical inlets. Thus accelerated, the stream of air then forms a “curtain” around the outer sides of the wheels. This reduces turbulence as well as drag and fuel consumption. At the same time, the fresh air provides optimum cooling for the engine and additional components such as radiator and intercooler.

If required, the optionally available 17-inch Streamline 370 light-alloy wheels additionally reduce eddy formation directly on the rims, further improving the aerodynamics of the BMW 1 Series Convertible. The result is increased driving stability, a more agile driving performance and less fuel consumption.
