Hispania Racing team boss Colin Kolles has hinted that the team could be prepared to launch a protest against off-throttle blown diffusers at next weekend's Monaco Grand Prix.
The team is one of only three teams not using the system, which the FIA had planned to ban ahead of the Spanish Grand Prix only to perform a u-turn after discussions with the teams.
With the issue set to be discussed by the Technical Working Group, it is likely that the diffusers will still be in place on the streets of Monte Carlo and Kolles said that could lead to the Spanish team making a protest over its continued usage.
"It is clear that the other cars are illegal and it brings the teams a huge advantage," Kolles told the BBC
. "You cannot influence the aerodynamics by hot exhaust gasses or any moveable devices.
"We have studied this very carefully. The point is it is not corresponding to the regulations. It brings the other teams a huge advantage.
"If this is not going to be stopped before Monaco we have no other choice than to make a protest. I cannot tell you at what stage during the Monaco Grand Prix [we would protest].
"The only reason why we are not considering it [now] is because we were not involved in any sporting decision today."
Red Bull team boss Christian Horner said he found the intended protest surprising, arguing that the Hispania – currently bottom of the championship standings – had 'bigger issues' to worry about.
Indeed, F1 2011 returnee Narain Karthikeyan underlined that by revealing post-race that a melting seat had made the 61 laps of the Circuit de Catalunya that he covered on Sunday something of a fiery experience. The Indian – 21st and last and five laps down at the chequered flag – was the sole HRT finisher in Spain, with team-mate Vitantonio Liuzzi departing the fray with gearbox woes, albeit rather happier with progress.
"It was a very hard race," conceded Karthikeyan. "The tyres were degrading a lot, especially the rear ones, making it very difficult to drive. The first few laps were alright, but then the rear started giving me a lot of problems. I also had some trouble with my seat – I burnt my back, and at times the pain was unbearable.
