Red Bull confirmed on October 31st that in 2007 it will use Renault engines and sister team Toro Rosso will be Ferrari powered. Red Bull had a two year deal for Ferrari engines, starting in 2006, but negotiated to end it early in favour of Renault. Toro Rosso, which competed with the restricted Cosworth V10 this season, will run the Ferrari V8s next season.
Renault commented: "Following the announcement of an engine supply agreement between Renault and Red Bull GmbH on 15 September 2006, Red Bull have confirmed that Red Bull Racing will use the homologated version of the French manufacturer's RS26 V8 engine from 2007 onwards."
Ferrari stated that the agreement with Red Bull Racing had been terminated with mutual consent and that the two-year contract with Toro Rosso will start in 2007 with an option to be extended a further year.
"We are pleased to be embarking on a new long-term relationship with Scuderia Toro Rosso," said Ferrari CEO Jean Todt. "It will allow us to strengthen our ties with the world of Italian motor sport and also to work with a team run by Gerhard Berger, our former driver and friend of Ferrari."
Red Bull already confirmed that its race drivers next season will be David Coulthard and Mark Webber. Toro Rosso has not made any announcement about its line up but it's thought likely that Scott Speed and Tonio Liuzzi will continue, despite rumours of Red Bull tester Robert Doornbos being a possibility to replace one of them.
