Since fuel efficiency, range in the case of EVs, plays a very important role nowadays, it is self understanding that among top priorities when designing a new car is aerodynamics.Inoue Makoto, chief designer of Nissan's Global Design Product Division, gives Leaf's rear design as an example.
The air flows coming from the roof, side and under the floor had to be separated. For that reason, the taillights have a a more convex shape in order to act as spoilers. Also, the lack of an exhaust sysem has enabled a much better design, aerodynamically, which would not be possible in the case of a car equipped with an internal combustion engine.
Even the design of the antenna has been carefully considered in order to limit the generated wind noise. Therefore, the antenna has a pentagon shape with a round tip. Another important area was the edge of the rear bumper, in order to have a clear separation of flow.
