Christian Horner suggested the problems with the RB10 are minor.
Feb.10 (GMM) Christian Horner has played down fears of a Red Bull crisis, insisting the problems with the new RB10 are "nothing major".
After four consecutive world championships at the tail-end of the former regulations, Red Bull's all-new V6-powered car managed only a handful of laps recently as the winter testing season for the all-new V6 era opened at Jerez.
"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," team boss Horner told Sky Sports News.
But despite suggesting the problems with the RB10 are minor, Horner was also giving no guarantees they will all be fixed by next week, when the second official test begins in Bahrain.
"Obviously there's quite a bit to do but there's still a fair bit of time before the first race," he said.
"Bahrain 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," Horner added.
