The team’s 2014 car managed just 21 laps of the Jerez circuit at the opening winter test. In contrast, rivals Mercedes completed 309 laps with its new W05. The RB10 suffered overheating and packaging issues with the new Renault power-unit, but Horner insists that there are no big problems that need fixing.
“There’s a few things we needed to tighten up on our side but nothing major and obviously Renault have some issues that they are tidying up as well,” he told Sky Sports News. “But these cars are so complicated that even small problems can cause big failures.”
He is confident that the issues will be resolved by the second test in Bahrain. “Obviously there’s quite a bit to do but there’s still a fair bit of time before the first race,” he added.
“The Bahrain test next week is an important test and we are working very hard at both Renault and Milton Keynes. We don’t want another test like Jerez but that’s what testing is for – you sort your problems out so as not to have them at the races.”
