New Clio Cup adopts the aerodynamic features first seen on New Clio Renaultsport 197. Very closely related to those used in Formula 1, the rear diffuser and the front wing-mounted air extractors contribute to the stability of the car at high speeds. New Clio Cup is the first entry-level sports hatchback to feature such a sophisticated aerodynamics setup.
The rear air diffuser is designed to reduce any lift that is naturally generated by the car’s profile without adversely affecting the finer points of the aerodynamic setup. By channelling airflow beneath the car, the diffuser accelerates and expels the air, creating a zone of low pressure, which "sucks" the car to the ground. The twin exhaust outlets fit perfectly into the diffuser without hindering its performance in any way.
The addition of a rear spoiler provides further reduction in lift.
A roof-mounted air intake is designed to ventilate the driver compartment.
Finally, the front wing-mounted air extractors also help to evacuate hot air from under the engine compartment. They eliminate unwanted turbulence and direct airflow along the sides of the car, which also helps to improve the car’s stability at high speeds.
