The Renault RE20 was a Formula One car raced by the Renault team in the 1980 season. The car was designed by François Castaing and Michel Têtu and designed using Ground effectaerodynamics. The car was powered by the 1.5L turbocharged Renault Gordini EF1 engine, which by 1981 was producing a reported 520 bhp (388 kW; 527 PS). This was roughly 50 more than the 3.0L Cosworth DFVV8 still in wide use at the time in Formula One, though Renault's power did lag behind the new 560 bhp (418 kW; 568 PS) turbocharged engine being used by Ferrari. In keeping with everything French on the car, the tyres used by Renault were Michelin.
The driving lineup for the all French team was made up at the time entirely of French drivers. Driving the RE20 in 1980 were Jean-Pierre Jabouille and René Arnoux, while in 1981 Arnoux continued with the team but Jabouille was replaced by a young Alain Prost who had made his Formula One debut in 1980 for McLaren.
The Renault RE20 achieved three Grand Prix wins during the 1980 season. Arnoux won both the Brazilian and South African races while Jabouille was the winner of the Austrian Grand Prix.
A modified version of the car, the RE20B, raced in first five races of the 1981 season. The RE20B was replaced by the Renault RE30.
