LONDON -- The Williams Formula One team will switch from Cosworth engines to units supplied by Renault for next season.
The two-year agreement will give Williams access to the Renault V8 engine that powered Red Bull to the 2010 championship.
Williams previously won four world drivers' and five constructors' championships with Renault engines between 1992 and 1997, when the team picked up the last of its nine constructors' titles.
Team principal Frank Williams says "we will not allow ourselves to dwell too much on the past. We must look to the future and continue to rebuild our on-track reputation."
Williams says it wants to extend the partnership into 2014, when turbocharged V6 engines will be standard.
