Last season, Ferrari supplied the engines to the main Red Bull team, while the second squad, Toro Rosso, was powered by engines from independent supplier Cosworth. Ferrari was hoping to power both teams for next season, and keep Red Bull Racing, with veteran drivers David Coulthard and Mark Webber already confirmed, from posing too great a challenge to the boys in red. But newly-crowned Ferrari CEO Jean Todt can't always get what he wants, as Red Bull switches to Renault power for 2007.
Toro Rosso (formerly Minardi) will become even more authentically Italian, motivated by Ferrari power for 2007 and 2008 with an option for 2009. STR is run by former Ferrari driver Gerhard Berger, but struggles to escape the back of the field. Last year the team also fielded Italian driver Tonio Liuzzi, but they've yet to announce their line-up for next season.
Had Ferrari secured deals with both Red Bull teams, their engines would be in over a third of the cars on the grid next year, including their own as well as the Spyker cars which switch from Toyota to Ferrari power for next season. Maranello already secured special dispensation from the FIA to supply engines to two teams, and that should be enough to gain extra testing data and support from the back of the field as Kimi Raikkonen and Felipe Massa fight for the title.
