What is Air Resistance?

Downforce is created when air moves through and over parts of the car.

Downforce is a force created by the air flow which pushes downwards.

Designers have to take this into serious consideration when designing the overall shape of the vehicles because some shapes are more aerodynamically streamlined than others.

Downforce pushes the tyres into the track enabling cornering speeds to be increased.
It also allows the cars to brake harder at high speed
this is important because of the long straight at Le Mans .
