Mark Webber has told his rivals to stop trying to find fault with Red Bull and concentrate on resolving their own issues.
Red Bull's latest front wing design concept has come under considerable scrutiny due to its flexibility at high speed, when it is supposed to remain static. Ferrari have also developed their own version and both have passed FIA tests.
But although no team has lodged a formal protest there have been plenty of complaints.
The FIA tests will be improved ahead of the Belgian grand prix after the Mercedes team principal Ross Brawn claimed they are "not correct". But after Red Bull's innovative exhaust blown diffuser was also frowned upon before rivals caught up last season, championship leader Webber feels the criticism is all a lot of hot air.
"Our guys have designed a car in the spirit of the regulations, and every time we are tested by the FIA, we pass," said Webber.
"So when people don't like what they see on the stopwatch, they have to justify their own positions sometimes. When there's pressure on people to perform and they're getting destroyed, that's how it is.
"Some teams have done certain things, other teams have done other things. McLaren incorporated the F-duct, which is a sensational idea.
We’ve turned the world upside down to try and do that which is not without resource difficulties, but that’s Formula One.
"We’re more than happy with what we have on the car, and we’re sleeping well at night. You should never penalise things that are ingenious, and people who are doing a good job, and that’s sometimes the case. There’s always something new to bring out of the cupboard."
Webber feels if the critics want to harp on about parity, then Red Bull should be allowed to equalise their engines in line with other teams.
At present the Renault powerplant is down on horsepower compared to the likes of Mercedes, as used by the German manufacturer, McLaren and Force India.
"We’ve been looking for engine parity for the last few years because we know we don’t have the most powerful engine," he said. "When we go to a track where there are not many straights, the car is good because we’ve had to try incredibly hard to get the car performing on those circuits.
"Other teams sometimes want everything, but we need parity on the engine and then it would be a fair game. That’s all we want, similar horsepower to other teams. It’s not a one-way street with this stuff you know.”
