In car design, ground effect is a series of effects which have been exploited in automotive aerodynamics to create downforce, particularly in racing cars. This has been the successor to the earlier dominant aerodynamic focus on streamlining .
Ekranoplan A-90 Orlyonok. A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (Russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water.

By 1981 the ground effect cars were so efficient and so fast that the drivers were suffering from the tremendous g-forces involved in cornering and braking. The FIA banned the moveable skirts fitted to the bottom of the cars' sidepods that were vital for achieving consistent ground effect and regulated a mandatory ground clearance of 6 cm, in the interests of driver safety.
The sliding skirts sealed the gap between the sides of the cars and the ground and prevented excessive air being sucked into the low pressure area under the car and dissipating the ground effect. Andretti described driving the 78 as if it were 'painted to the road'. [8] The Lotus 78 being tested at the Lotus test track in Hethel

The Chaparral 2J is a sports prototype race car, designed and developed by Jim Hall and Hap Sharp, and built by American manufacturer Chaparral. It conformed to Group 7 regulations and competed in the 1970 Can-Am Championship series. [5] [6] It is an early example of a ground effect racing car. [7] The 2J was the most unusual Chaparral.
