The Original Ground Effect F1 Era

Ground effect in Formula 1 refers to the aerodynamic phenomenon that occurs when a car’s bodywork creates a low-pressure area underneath the car, effectively suctioning it to the track. This allows the car to generate a significant amount of downforce, which in turn increases grip and stability.

In the 1970s, Formula 1 teams began to experiment with ground effect aerodynamics as a way to gain an edge on the competition. The regulations at the time allowed for wide cars and wings, which provided a large surface area to create downforce. Teams began to design cars with low, wide skirts that ran along the side of the car, and these skirts effectively sealed off the area under the car, creating a low-pressure zone.

One of the most notable examples of ground effect in Formula 1 during the 1970s was the Lotus 78. Designed by Colin Chapman and Peter Wright, the car featured a wide, low-slung body and side skirts that effectively sealed off the area under the car. The car generated so much downforce that it was able to corner at much higher speeds than its rivals. The Lotus 78 went on to win six races in the 1977 season, and Mario Andretti, who drove the car that season, came close to winning the championship.

Another example of ground effect in Formula 1 during the 1970s was the Brabham BT46B. The car, designed by Gordon Murray and Ralph Bellamy, featured a fan at the back of the car which sucked air from under the car, creating a vacuum and even more downforce. The car won its debut race in 1978, but the FIA banned the use of fans in Formula 1 at the end of the season.

However, as teams continued to push the boundaries of ground effect aerodynamics, the FIA began to impose stricter regulations on the design of the cars. The wide skirts that had been used to seal off the area under the car were banned, and the cars were required to have a flat bottom. These regulations effectively ended the era of ground effect in Formula 1, and teams turned to other aerodynamic solutions to generate downforce.

In conclusion, ground effect played a significant role in Formula 1 during the 1970s as teams were experimenting with new aerodynamic solutions to gain an edge on the competition. The Lotus 78 and Brabham BT46B were notable examples of ground effect in Formula 1 during the 1970s. However, as teams continued to push the boundaries of ground effect aerodynamics, the FIA began to impose stricter regulations on the design of the cars, effectively ending the era of ground effect in Formula 1.
