Australian Grand Prix organisers claim that their race contract was breached this season, as a result of the sport’s new turbocharged engines being much quieter than the previous V8 powerplants.

Australian Grand Prix Corporation (AGPC) Chairman Ron Walker says he has already talked to Formula 1 supremo Bernie Ecclestone over the matter, with both men eager for there to be significant changes.

”I was absolutely delighted with the whole weekend, but I was not too happy with the sound,” Walker is quoted as saying by The Age.

“We are resolving that with Bernie. It’s clearly in breach of our contract. I was talking to him on Sunday and it’s not what we paid for. It’s going to change.

“He’s horrified about it. It will be an issue for all promoters all round the world.”

Walker warned that if steps are not made in the future, it could severely affect attendance levels.

”We are an entertainment company and we have to entertain the public,” Walker went on to explain.

“Everybody was talking about it. When you take the excitement away, you have trouble selling tickets. You have to create demand and part of that demand is people liking the noise of the race cars.”
