Horner hints Red Bull considering 2011 engine supply

Christian Horner has indicated there is no guarantee that Red Bull will still be powered by Renault engines beyond 2010.

The team principal is quoted by Italy’s Autosprint as saying he is happy with the relationship between Red Bull and Renault, but he reportedly wants the French marque to be allowed to catch up the power deficit to the leading suppliers.

"We’ve shown that we have an excellent chassis, but the engine has maybe 20 or 30 horse power less than the competition.

"We are happy with the relationship with Renault," said Horner, who wanted to switch Red Bull to Mercedes engines this year but was vetoed by the German supplier’s existing customers.

Autosprint indicated that Red Bull’s current engine deal expires at the end of the current season.
