The Renault R25 was the Formula One car entered by Renault in the 2005 season. The chassis was designed by Bob Bell, James Allison, Tim Densham and Dino Toso with Pat Symonds overseeing the design and production of the car as executive director of Engineering and Bernard Dudot leading the engine design.
The car won both the Drivers' and Constructors' Championships in 2005, the first titles for any car racing with a French licence since the Matra MS80's triumph in the 1969 season. It also became the first Renault-powered Formula One car to win both championship titles since the Williams FW19 in and also the first Enstone-based Formula One car to win the world constructors' championship since the Benetton B195 in .
History
During the season, the car turned out to be slower than the McLaren MP4-20 at numerous points, with the win tally being 8–10. Reliability and consistency prevailed in the end, with Fernando Alonso and Giancarlo Fisichella taking the car to the last win and titles for a V10 powered Formula One car, marking the end of an era.
This car also claimed Michelin's first of only two titles since its return in Formula One, winning the title again with Renault (the R26 2006-spec car) in the 2006 season, the last for the French tyre maker. The R25 was the first Constructors' Championship winning car since 1991 not to have been designed by either Adrian Newey or Rory Byrne.
Over 19 races, it scored 191 points, 8 wins, 15 podiums and was fully out of the points just twice in 18 starts (not counting the United States Grand Prix where both Renault drivers, in common with all their fellow Michelin tyre runners, withdrew prior to starting).
The R25 was also the last Renault Formula One car to use a 6-speed gearbox before the switch to a mandatory 7-speed gearbox in the following season.
The R25 was fitted with a mass dampener in its nosecone allowing the car to remain more stable in corners, this was later banned by the FIA as an aerodynamic rather than a mechanical device.
Sponsorship and livery
Renault used the 'Mild Seven' logos, except at the Canadian, French, British, Turkish, Italian and Belgian Grands Prix. At these races, the team replaced the logos with Phoenix, flowers, tribals and flame graphics as well with the random text "Team Spirit".

Later uses
In Episode 8 of Series 10 of the BBC show Top Gear, in 2007, presenter Richard Hammond drove the R25 around the Stowe Circuit at Silverstone, completing two laps.
On 11 December 2020 Alonso drove the car for the first time in 15 years, hours before the start of the first practice session shown on Sky Sports, and after the qualifying session for the 2020 Abu Dhabi Grand Prix. The car used Pirelli demo slick tyres, rather than the original Michelin grooved tyres.
