Red Bull has denied it is running a performance-boosting active suspension set-up, following speculation within the Formula One paddock that the team is using the outlawed system.
Red Bull's qualifying pace has prompted talk that the team is using a damping system that lowers the car for faster qualifying runs before being raised again for the race.
It is claimed this the set-up works by using compressed gas to push the car down for qualifying. The gas could then be released overnight to allow the car to run higher to accommodate heavier fuel loads in the race.
However, Red Bull team boss Christian Horner has denied the team is using such a system. The Red Bull RB6 was given the all-clear on Saturday following a thorough inspection from the FIA, and the team has said it will protest any rivals that run such as system, following claims McLaren was set to introduce its own version for the next round in China.
“We haven't got one, it is as simple as that,” said Horner. “If McLaren have one in China we will protest them, because theoretically they are illegal. The FIA had a good look at our car [in Malaysia] on Saturday night and they are happy with it. They will struggle to find anything because there simply isn't anything there."
Red Bull claimed a one–two at the Malaysian grand prix on Sunday; Sebastian Vettel beat pole-sitter Mark Webber into the first corner and led the race from that point onwards.
