Australian Grand Prix organisers claim their contract may have been breached because the Formula One cars were not loud enough.
The quieter cars under this season's new F1 rules detracted from the "sexiness" of the race and meant Melbourne did not get what it paid for, Australian Grand Prix Corporation chief executive Andrew Westacott says.
Grand Prix chairman Ron Walker has already been in discussions with Formula One chief Bernie Ecclestone and made it clear organisers are unhappy.
"One aspect of it was just a little bit duller than it's ever been before and that's part of the mix and the chemistry that they're going to have to get right," Westacott told Fairfax Radio on Monday.
"Ron spoke to (Ecclestone) after the race and said the fans don't like it in the venue.
"We pay for a product, we've got contracts in place, we are looking at those very, very seriously because we reckon there has probably been some breaches."
Westacott said he did not need earplugs in pit lane at the start of the race and described the sounds as being like harpsichords in a chamber orchestra.
He expects hardcore racing fans in Europe will be even less impressed by the quieter cars.
