World champions Renault will supply customer engines to one of Red Bull's Formula One teams next season, autosport.com has learned.
The French car manufacturer have signed a deal with the energy drinks company to provide V8 power units in 2007. However, it has not yet been decided which team will get these engines.
Red Bull boss Dietrich Mateschitz flew into Monza on Sunday to put his signature on the contract after months of negotiations to secure power units for his teams.
Although it is not known when an official announcement will be made, Mateschitz has confirmed that a deal with Renault has been agreed.
"We will have two cars with Ferrari and two with Renault engines in 2007," he said.
Mateschitz's intention is for the Renault supply to go to his main team Red Bull Racing, but such a move is dependent on Ferrari agreeing to release the Milton Keynes-based outfit from their current contractual commitments.
Ferrari have so far shown no willingness to negotiate on the terms of the original two-year contract that was signed last season.
Should a deal not be forthcoming then the Renault supply will go to Scuderia Toro Rosso, who are ending their contract for Cosworth V10 engines one year early.
It is understood that Red Bull Racing technical chief Adrian Newey has been pushing hard for a supply of Renault engines for the 2007 challenger that he is currently working on.
He is believed to favour the unit primarily because of its cooling characteristics, which would allow Newey to sculpt a more aggressively aerodynamic car.
