The uncertainty regarding Red Bull Racing's engine partner in F1 2010 looks to have been resolved, with the entry list released yesterday by governing body the FIA noting that the two energy drinks-backed cars will be Renault-powered once again next season.
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, 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.
It was widely speculated within the grand prix paddock that Red Bull was keen to run tie up with Mercedes-Benz in 2010 – but that move is understood to have been vetoed by either Brawn GP or McLaren or both – and the Milton Keynes-based squad's team principal Christian Horner recently revealed that a choice would need to be made soon.
“We will have to make an engine decision very shortly,” the Englishman acknowledged. “We've enjoyed a great relationship with Renault over the last three years – they treat us with excellent parity and have been an important part of our success this year. We will have to consider very, very carefully if we are to change engine-supplier for next year. We are reaching a position in our own minds, and we will firm that up I would think very soon.”
Now, it appears that decision may have been made.
