With the current Williams-Renault partnership a far cry from the successful team-up in the 1990s which accomplished five constructors' championships in a span of nine years, the Formula 1 team is now ditching the French engine provider in favor of Mercedes-Benz from the 2014 season onward.
"Mercedes-Benz has been one of the sport's most successful engine suppliers, and we believe that they will have an extremely competitive engine package," said Williams F1 founder and team principal Frank Williams. "I would like to take this opportunity to thank Renault for their continued hard work since we renewed our engine partnership at the beginning of the 2012 season. We have enjoyed a strong relationship that has resulted in much success over the years, including powering us to winning ways once again last year at the Spanish Grand Prix."
Under the agreement, Williams F1 will be supplied with a "power unit" that consists of an internal combustion engine and an energy recovery system by Mercedes AMG High Performance Powertrains, with the team continuing to use its own transmission system.
The new partnership comes at a time when the sport will begin using 1.6-liter turbocharged V6 engines in place of the current naturally aspirated 2.4-liter V8 engines.
"It is a very proud moment for everybody at Mercedes AMG High Performance Powertrains to announce the start of this new partnership with the Williams F1 Team," shared Mercedes AMG HPP managing director Andy Cowell. "Williams is one of the sport's iconic names and we are very excited to be working together toward a successful future under the new regulations. A further positive is that this new agreement provides Mercedes-Benz with the long-term stability of supplying our works team and at least two partners from the 2015 season onward, following the conclusion of our relationship with McLaren at the end of next season."
