Red Bull Racing has confirmed that Renault will continue to supply the team with engines for F1 2010.
It had been widely speculated that the Milton-Keynes based outfit was keen to switch to Mercedes-Benz power-plants next year, however the uncertainty regarding the squad's engine partner looked to have been resolved a few weeks back, when the entry list released by the FIA, the sports governing body, noted that the two energy drinks-backed cars would be Renault-powered once again.
Today that was officially announced and under the agreement Red Bull Racing will use identical engines to those used by the Renault F1 Team.
"We can confirm that our productive partnership with Red Bull Racing will continue in 2010," said Renault F1 team president, Bernard Rey. "The close relationship between Renault and Red Bull Racing has grown since 2007 – and this year it resulted in six victories and second place in the 2009 Constructors' Championship.
"Together we believe that we can build on this success and contribute to Red Bull Racing's future endeavours."
Red Bull has been supplied by Renault for the past three years, but the relationship has not always been the easiest - with considerable criticism of the French manufacturer's engine in 2008 in particular, as its power output increasingly failed to match that of its rivals and cost RBR drivers dear along straights and into the braking zones.
There were further issues in 2009 too, when a spate of failures arguably derailed Sebastian Vettel's title bid at a pivotal moment – and threatened to land the young German with a grid penalty in the closing races for running out of available engines to use. Despite that though, Red Bull team boss, Christian Horner, maintains that they are pleased to continue working together.
"2009 has been Red Bull Racing's finest season to date. In one year, we've achieved six wins and four one-two finishes, none of which would have been possible without the excellent support and assistance we have received from our partners at Renault," Horner stated.
"We are extremely happy with the way they work with us and are looking forward to continuing our fruitful partnership with Renault in 2010."
