Sebastian Vettel has revealed that he will still be powered by a Renault engine in 2010.
Whether Red Bull is staying with the French marque or switching to Cosworth or Mercedes has been the subject of much speculation.
But when the FIA appeared to end the uncertainty by recently listing Renault as the team's 2010 supplier, Red Bull Racing boss Christian Horner insisted the news is not yet official.
However, when questioned on the topic during the RTL programme '2009! Menschen, Bilder, Emotionen', 22-year-old driver Vettel answered: "We're staying with Renault."
