That negative pressure was created by the internal shaping of the sidepods, which had an opening at the front, close up behind the front suspension, ostensibly to feed the radiators that were placed there. Those skirts were to make a seal between the underbody and the road, a crucial part in propagating negative pressure beneath the car.

The proportions of the 78 (as seen in the image below) were very different to those of its contemporaries, and therein lay the clue to the radically different way its aerodynamics worked. IN NUMBERS: The staggering stats behind the development of the all-new 2022 car Forty years ago, the 78’s successor, the Lotus 79, became the first ground effect car to win the world championship, with Mario Andretti at the wheel. The car which made that breakthrough was the Lotus 78 of 1977, which ushered F1 into the era of ground effect. ![]() Getting the principle to work on a skinny-bodied, open-wheel single seater initially seemed unfeasible. ![]() But they were cars with wide, wheel-enclosing, bodywork. The idea of using the underside of a racing car to generate negative pressure and effectively suck the car towards the track had first been exploited in the Can-Am sports cars series in the 1960s. In this article first published in August 2018, Mark Hughes and Giorgio Piola look at the technological tour de force that was the Lotus 79 – the car that famously took Mario Andretti to the 1978 drivers’ title, the first to be claimed in a Formula 1 car featuring ground effect technology… In 2022, Formula 1 will embark on a new ground effect era amid a sweeping new set of rules changes.
