Alonso scotches Red Bull cheat rumours



Sebastian Vettel has laughed off accusations Red Bull is using traction control, saying his rivals will never figure out why his car is as fast as it is this year.

Following his dominance at the Singapore Grand Prix, ex-F1 boss Giancarlo Minardi speculated on his blog that Red Bull was running some form of traction control on the RB9 to allow Vettel to get on the power earlier - an accusation the Red Bull driver was quick to laugh off. All teams use the same ECU, effectively banning traditional forms of traction control, but asked whether the accusations bothered him, Vettel said his rivals would never get to the bottom of the reasons behind Red Bull's success.

"We are pretty proud of the system we have because other people will never figure out how we have done it," he said. "Constantly we try to improve the car, that is part of the homework we try to do.

He added: "We were playing around quite a lot in practice [in Singapore] and the first time it worked was in the race. I'm quite confident because other people will never figure out how we do it."

However, Vettel said there were no guarantees his recent success would transfer to this weekend's race in Korea.

"Rain is forecast on Sunday, and not just a bit or rain, it could be pretty heavy," he said. "But it's the usual game, we will start by trying to set the car up well on Friday in practice. We have seen this year that the package is strong no matter where we go, but you cannot expect the car to be strong at the front again just because you were at the last couple of races."
