Team Lotus pioneered the use of 'ground effect' aerodynamics with their Type 78 and 79 cars.
Introduced in 1977 (Lotus 78) and perfected in 1978 (Lotus 79), ground effect used shaped underbodies and side skirts to create low pressure, dramatically increasing downforce. Mario Andretti won the 1978 title with the Lotus 79.
