Red Bull rules out using KERS

Red Bull figures Christian Horner and Sebastian Vettel have denied rumours the team is considering introducing KERS within the next few races.

"So late in the season, that would be a big risk," team boss Horner is quoted as saying by Germany's Auto Motor und Sport. "Without KERS our car should be capable of winning at Spa."

German race driver Vettel agrees that, in the midst of a championship contest with Brawn, experimenting with KERS would not be a good idea.

"We would need two races to set up the car optimally with the ballast, and even then there would be no guarantee that we would profit from the system," he said.

Brawn GP also ruled out using the technology at any of the remaining six races of the season.

"Trying to put it in this late in the season would be insane," championship leader Jenson Button is quoted as saying.

Team boss Ross Brawn ruled out the scenario from a technical perspective. "It is not an option for us because our car would be too heavy.

"Even with the Mercedes system it is not possible for us to put (KERS) in without then having a weight handicap," he added, explaining that there may also be problems with cooling the system given the design parameters of the BGP001 car.
