An aerofoil is a shape that is designed to create lift when air flows over it. It is commonly used in the design of wings and other aerodynamic surfaces to help airplanes and other aircraft stay in the air. Full definition
Perhaps the most impressive modification happened at the rear... not only does DMC install a high rear aerofoil wing on top of the engine cover, but they also put a new base spoiler flush with the bodywork to create a perfect airflow coming over the clear carbon fiber covered roof... add a massive lower rear diffuser and some amazing looking exhaust tips and you have a clear winner... a street legal Huracán with track inspired looks.

This concept uses a series of aerofoil shaped wings, together with fixed solar panels, where the wings may change position to track the sun, or to sail using the wind. (bluebird-electric.net)
These changes also help to increase downforce at the front, balanced by the addition of a re-profiled spoiler on the rear aerofoil with a raised rear edge. (carsuk.net)
