In 1980 the 'Williams - FW07B' was driven by Alan Jones and Carlos Reutemann, and the car was efficient in creating downforce from its ground effect side 'Skirts'.
For 1981, the 'Williams - FW07B evolved into the 'FW07C' without the skirts and further work was done to the suspension, especially after the 'FIA' banned the moveable skirts needed for effective ground effect.

In motor-racing , a designer's aim is for increased downforce and grip to achieve higher cornering speeds. From the late 1960s, a substantial amount of downforce was generated by using 'Wings' (which is not a type of ground effect).
Designers focused their efforts at understanding air flow around the sides and underside of the racing car to increase downforce with less drag than compared to using a wing. This ground effect can be observed when the racing car (with 'Skirts') is travelling fast enough and its ride height is close enough to the ground, the car will be drawn towards the ground. This is due to 'Bernoulli's Principle'; as the racing car gets closer to the ground, the cross sectional area available for the air passing between it and the ground shrinks. This causes the air to accelerate and as a result pressure under the car drops while the pressure on top is unaffected, and together this results in a net downward force.
