Vettel has confidence in Red Bull's KERS
Sebastian Vettel is confident his Red Bull team has got on top of its KERS problems ahead of the Turkish Grand Prix.
Vettel's RB7 has been the class of the field so far this season but its Achilles heel has been KERS, which has worked sporadically and failed altogether at times. Adrian Newey's design team has modified the units supplied by Magneti Marelli and Renault to better fit the Red Bull's tight aerodynamic packaging, but in doing so it appears to have compromised the cooling.
On Wednesday Red Bull advisor Helmut Marko insisted Red Bull had solved the problems over the Easter break and Vettel said he has no reason to doubt that.
"We have had some problems but have had very good people working on it," Vettel told Auto Motor und Sport. "That's why for this next race I am not worried."
He also revealed that the RB7 will have some other improvements for Turkey this weekend.
"When I asked the team what to expect, I received many answers," Vettel answered coyly. "You'll have to ask them for yourself."
When Metro put that very question to Christian Horner, the Red Bull team principal replied: "Our main focus of attention has been to try to get on top of the KERS issues. It's a relatively new technology to us but we are working hard to understand and get on top of it. We've got some updates which hopefully will address some of the issues we've had in the early races."
Returning to Istanbul Park for this weekend's Turkish Grand Prix has added significance for Red Bull, as it was at this circuit last season that the relationship between Vettel and team-mate Mark Webber imploded when the pair collided on track. One year on, Vettel said: "I cannot change what has already happened, but I can learn from it."
The German driver was clearly sticking to the party line as Horner added: "What happened last year, happened. Lessons were learned from it and we are looking forward to going back."
