Renault for Red Bull, Ferrari for STR.
Having agreed a deal with Renault earlier in the season, in addition to its existing agreement with Ferrari, Red Bull has confirmed its engine plans for the 2007 Formula One season.
Red Bull agreed a two-year contract with Ferrari for the 2006-07 seasons but a difficult year saw the team starting to look elsewhere for an engine supplier for 2007 - although such a move depended on Ferrari agreeing to switch its supply of V8 power over to Red Bull's 'second team' Toro Rosso.

Red Bull agreed a two-year contract with Ferrari for the 2006-07 seasons but a difficult year saw the team starting to look elsewhere for an engine supplier for 2007 - although such a move depended on Ferrari agreeing to switch its supply of V8 power over to Red Bull's 'second team' Toro Rosso.
A two-year deal, covering 2007-08, with Renault was then announced in September with Red Bull able to choose whether the engines went into the back of the new Red Bull RB3 or were passed on to STR.
With RBR team boss Christian Horner admitting that it would 'make sense' for Toro Rosso to run with Ferrari engines - Italian engines for an Italian team - the Scuderia have agreed to the switch, which means the first Red Bull car penned by leading designer Adrian Newey and driven by David Coulthard and Mark Webber will be powered by Renault.
Toro Rosso will inherit the Ferrari supply, replacing the V10 Cosworths inherited this season following the purchase of the team from Minardi.
