Aerodynamics are a very important part of automotive design, since it singlehandedly can influence by a high margin factors like fuel consumption, noise levels, top speed and undesired lift forces experienced by any vehicle at high speed. A more streamlined car will have a lower drag coefficient, thus increasing its mileage, its top speed and also lower wind noise levels.
On the other hand, there has to be a balance between a clean aerodynamic shape that can also provide downforce at very high speeds. High performance cars use different types of spoilers, integrated bodykits and diffusers to create venturi effects and improve the vehicle’s road grip. Almost all aerodynamic elements on modern cars were inspired by the aviation industry and are designed using wind tunnels and computer simulations.
