The Renault RS01 was the first Formula One car to be powered by a turbocharged engine.
 It was also the first to use radial tyres, which were provided by Michelin.
 Designed by André de Cortanze and Jean-Pierre Jabouille, it first appeared at the 1977 British Grand Prix.
 The rules of F1 at the time permitted 3.0 litre engines of natural aspiration, with a clause for a 1.5 litre supercharged or turbocharged engine.
 None of the teams had pursued this avenue, and stuck to Ford Cosworth DFV engines, whilst Ferrari, Matra and Alfa Romeo concentrated on developing Flat-12 engines for their cars, and their customer teams of Ligier and Brabham.
 Leading French car manufacturer Renault decided to develop a 1.5 litre turbocharged engine, and a car to accompany the powerplant.
