Mark Webber won't move over for Sebastian Vettel from the lead of the Indian GP

Mark Webber insists he will "go for it" at this weekend's Indian Grand Prix and that moving over for Sebastian Vettel is not an option.

Red Bull's ascendancy has come on the back of recent upgrades such as the team's own version of the double DRS pioneered by Mercedes. Webber admitted that, in such a competitive season, Red Bull's clear step forward has come as a surprise but warned against complacency. "It's just such a fine margin, the way these cars operate in such a small window. There's just not one thing you bolt on the car and go, 'Oh that's it'," he said. "That was what we had already three or four races ago. It's not old but it can be superceded pretty quickly. That's the business that we're in. It's a constantly evolving car. "We have done well to recover the extremely high standard of our previous two years, given that in the first part of the Championship Seb and I had something like four or five podiums in 18 attempts. "So we're getting better but we're not getting ahead of ourselves." Webber is confident Red Bull can produce more of the same in India, where Vettel won comfortably in the inaugural race 12 months ago. "It should be pretty good again. How much company we'll have, how tight it will be...it's going to be the normal guys, obviously, Ferrari and McLaren," he added. "They're always there or thereabouts, particularly the Ferrari on Sunday (but) the Ferrari less so on Saturday. McLaren are strong on Saturday but then at Suzuka they weren't super-strong in the race. "So I think we should be okay. We're not coming here thinking, 'Well, it's like Monza'. We should be pretty good."
