Renault

Renault has played several distinct roles in Formula 1: pioneering engine maker, championship-winning works team and long-running power-unit supplier. The French manufacturer first entered in 1977 with a revolutionary turbocharged engine, the RS01, which was initially mocked as the 'yellow teapot' for its unreliability before turbo power came to define an entire era of the sport.

Renault's works team won races in the early 1980s with drivers including Alain Prost and René Arnoux but never quite landed a title in that first spell. Its greatest success came after it bought the Benetton team and returned as a full constructor, winning back-to-back drivers' and constructors' championships with Fernando Alonso in 2005 and 2006.

As an engine supplier Renault powered Williams and Benetton to multiple titles in the 1990s and Red Bull to four straight championships from 2010 to 2013, making it one of the most successful power-unit manufacturers in the sport's history before the works team was rebranded as Alpine.

Renault's influence on Formula 1 runs deeper than its own race wins. By introducing the turbo engine it changed the technical direction of the entire sport, and as both works team and supplier it sat behind a remarkable number of championships. Its blend of innovation and works ambition leaves a lasting mark on the French racing tradition.
