The original F1 ground effect era (late 1970s-early 1980s) used inverted wings and side skirts to create powerful suction, “sucking” cars to the track for immense cornering grip, pioneered by Lotus ...

Ground effect is the reduction of an aircraft's induced drag when flying very close to a flat surface, caused by the deflection of downwash, leading to improved performance like reduced thrust ...

Ground effect vehicles exploit the increase in lift and reduction in drag experienced when flying close to a surface. By trapping a cushion of high-pressure air beneath their wings or lifting surfaces ...
