Red Bull Racing team boss Christian Horner has reiterated that the Milton Keynes-based outfit is not running any sort of ride height adjustment system.
There has been a lot of speculation about the Renault-powered RB6 given its dominance in qualifying so far this season and prior to this weekend's Malaysian Grand Prix there was even rumours the FIA was investigating the matter [see separate story - click here
Following scrutineering at Sepang on Saturday though the RB6 was declared legal – and now Horner has warned if any other teams do try to develop something for China that allows the ride height to be changed according to the amount of fuel on board, then Red Bull will protest it.
"We haven't got one, it is as simple as that," Horner told ESPN
. "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."
With rumours persisting though, the FIA is now thought to be considering allowing a change to ride heights between Saturday and Sunday - although it will require the unanimous support of all of the teams.
"I would support it, as it would probably save us a bit of money," Horner added in the same report on ESPN
Meanwhile McLaren boss Martin Whitmarsh told the BBC
recently that his team could have its own form of 'active suspension' for Shanghai.
"Frankly, a few months ago, if the engineers had come to me and said 'we're going to design this system', I would have said 'actually, I don't think it's permissible'," Whitmarsh told reporters in Melbourne.
"But it looks like Red Bull and some other cars are able to run lower in qualifying than you would expect if they are then going to fill the car with fuel afterwards. Thus there's some evidence that such systems are considered legal and, if they are, then we're going to get one as quick as we can. It's an opportunity for us to have a look at it and, as you can imagine, we're working quite hard on those systems now."
