Renault R25

The Renault R25 was the Formula One car entered by Renault in the 2005 season.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 1969.

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 (and also second-to-last) title 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 car was also one of only two championship winners since 1991 not to have been designed by either Adrian Newey or Rory Byrne (the other, unsurprisingly, was its successor).^{[citation needed]}
