History

Technology: how racing cars changed shape.

Racing has always been a testing ground. The big changes, from where the engine sits to how air is used to press the car onto the road, tended to arrive in one series and spread, and rule makers often answered with bans.

Early ideas that stuck

  • Engine in front. Britannica credits Émile Levassor with placing the engine at the front of the car, ahead of the driver, around 1891.
  • Quick tyre changes. At the first Grand Prix in 1906, Renault used Michelin's detachable rims, which made tyre changes faster when only the driver and riding mechanic could work on the car (Forix).
  • The mirror. Ray Harroun's 1911 Indy 500 winner carried what many consider the first rear-view mirror on a race car (WRTV), and he drove it without a riding mechanic (National Park Service).
  • A proving ground. The National Park Service describes the Indianapolis Motor Speedway as a test bed for rear-view mirrors, front- and all-wheel drive, overhead camshafts, turbochargers and tyres.

The engine moves behind the driver

The 1930s Auto Union Grand Prix cars designed by Ferdinand Porsche already placed a 16-cylinder engine behind the driver, a layout Audi calls mid-engined in modern terms. The idea took hold in Formula One two decades later. Goodwood describes the Cooper T51, in which Jack Brabham won the 1959 title, as the rear-engined car that revolutionised the sport. Brabham kept his title in 1960 in the T53 after five straight wins, and Cooper kept the manufacturers' title ahead of Lotus and Ferrari.

Indianapolis followed. Brabham brought a rear-engined Cooper-Climax there in May 1961 and finished ninth from 13th on the grid. Jim Clark was second in a Ford-powered Lotus in 1963, and in 1965 he won by nearly two minutes, the first Indy 500 win for a rear-engined car. Of the 33 starters that year, 27 had the engine behind the driver (IMS).

Wings

Goodwood credits Jim Hall's Chaparral sports cars with pioneering aerodynamic downforce. The Chaparral 2E, built for Can-Am, had a large rear wing the driver could flatten with a pedal to cut drag, and its radiators were moved into ducted sidepods. Wikipedia describes a later Chaparral, the 2J, which used a second small engine to drive rear fans that sucked the car down onto the track, an idea that influenced later fan cars in Formula One.

The sources date wings in Formula One slightly differently. Goodwood says Ferrari and Brabham were first to run inverted wings, at the 1968 Belgian Grand Prix, with Lotus soon following with tall wings on struts mounted to the suspension. Forix dates Hall's use of wings to 1965 and the first F1 wings to 1967, with high wings standard from Spa in 1968. Both agree on what happened next: at the 1969 Spanish Grand Prix at Montjuïc, wing failures caused crashes for Graham Hill and Jochen Rindt at the same place, and at the following race, Monaco, the sporting authority (the CSI) met in emergency session and banned unrestricted wings.

Ground effect

Ground effect uses the shape of the car's underside, rather than wings alone, to create downforce; our how grip works page explains the principle. Motor Sport traces the first era:

YearWhat happened
1977The Lotus 78 uses the whole underside to make downforce, with short skirts sealing the sides, and wins five races.
1978The Lotus 79 adds full-length sliding skirts; Lotus dominates and Mario Andretti becomes champion. Gordon Murray's Brabham BT46B fan car wins the Swedish Grand Prix with Niki Lauda and is then withdrawn by Brabham, which Motor Sport says was not a ban.
1981FISA sets a 6 cm minimum ride height; Brabham answers with hydraulic suspension that lowers the car at speed.
1983Flat bottoms become mandatory, removing the venturi tunnels and skirts (Formula 1; Motor Sport). Mid-race refuelling is banned the same year; it returns in 1994.
2022Ground-effect aerodynamics return, with 18-inch wheels and a 798 kg minimum weight (Motor Sport).

The turbo era, 1977 to 1988

Renault's RS01, driven by Jean-Pierre Jabouille, was the first turbocharged car to race in Formula One, at the 1977 British Grand Prix (WhichCar; Goodwood). The venue of its first win is reported two ways. Zwischengas gives the French Grand Prix at Dijon on 1 July 1979, with a 1.5-litre Renault V6 turbo; WhichCar names the 1979 Monaco Grand Prix. The Dijon account is the one that matches the wider record we read, and the Monaco version looks like an error.

Nelson Piquet became the first turbo-powered world champion in 1983 in the BMW-engined Brabham BT52, whose engine Formula 1 says approached 1,000 bhp in qualifying form. Goodwood puts qualifying outputs of the era as high as 1,400 or 1,500 PS; we could not corroborate those figures elsewhere. Goodwood records that turbos were restricted in 1987 and 1988, and in 1988, the last turbo season, McLaren-Honda drivers Ayrton Senna and Alain Prost won 15 of the 16 Grands Prix (WhichCar).

The 2026 rules

Formula 1 says the 2026 cars give up the venturi floor tunnels of the ground-effect era for a flatter floor, and add movable front and rear wing elements that switch between a "Corner Mode" and a "Straight Mode". The wheelbase is 200 mm shorter, the floor 100 mm narrower, and the minimum weight falls from 800 kg to 768 kg. Safety changes in the same package are on our safety page, and the 2026 season itself, still in progress as of October 2026, is on our Formula 1 page.

Simulators

Racing technology now includes the machines drivers train on. All of the following comes from Wikipedia. Namco's 1982 arcade game Pole Position introduced qualifying laps, computer rivals and the chase view from behind the car. Papyrus's Indianapolis 500: The Simulation (1989) is often called the first true PC racing simulation and sold more than 200,000 copies, and Papyrus followed with Grand Prix Legends (1998), based on the 1967 F1 season. Gran Turismo (1997) was seen as the most realistic console sim of its day. rFactor arrived in 2005, and Papyrus co-founder David Kaemmer launched the subscription simulator iRacing in 2008. Nissan and Sony's GT Academy, run from 2008 to 2016, turned players into racing drivers, with 24 graduates over eight seasons, among them Lucas Ordóñez and Jann Mardenborough. The official F1 esports series began in 2017, and when COVID-19 stopped real racing in 2020, sim racing streams drew up to 400,000 viewers. See sim racing for how it works today.
