Motorsport boss Max Mosley has given a clear indication that Formula One manufacturers have no choice but to follow the radical rule changes made to the sport earlier this week.

And the president of the sport's governing body is to offer a $1m reward for anyone providing evidence that teams are cheating.

On Wednesday, the International Automobile Federation (FIA) issued a raft of new rules designed to cut costs and make racing more competitive.

Electronic aids such as traction and launch control are to be eliminated by 2004 at the latest with the FIA moving to have them taken off cars during the coming season.

Two-way telemetry (which allows changes to be made to the cars from the pits while they are out on the track) will not be allowed, nor will radio contact between the driver and team.

The "whistle-blower" offer is part of the of the zero tolerance approach announced by Mosley and F1 supremo Bernie Ecclestone with regard to existing rules in 2003.

And Mosley has once again made it clear that the threat of an F1 breakaway will not hinder the quest to revamp the sport.

"If a major manufacturer doesn't like it, too bad," said Mosley.

"If a major manufacturer pulls out of the sport because of it (the rule changes), again too bad.

"What we will gain from these rule changes is far bigger than what we will lose by their absence."

New measures

Pit to car telemetry banned No radio contact between driver and team Spare car cannot be used No access to cars between final qualifying and the race Standard braking systems and rear wings to be introduced from 2004 Electronic aids to be eliminated by 2004 Engines to last two races from 2005

Representatives of the major European carmakers, who are threatening to create their own championship from 2008 and have set up a company called GPWC to run it, met in Germany on Thursday.

The FIA has said that while it wanted to abolish traction control this season, it would allow the systems to remain in use until 2004 if teams could prove it would cost more to replace them.

"I would guess they will (use traction control this year) but they may all agree to end it sooner," said Mosley.

"They've undertaken to discuss it and try to see if they can."

Mosley, who expects some teams to resist, said he already detected some problems with McLaren.

"McLaren have a position that reminds me of America's during the Cold War, when they spent so much to win that conflict, also because nobody could match them on an economic level."

Team technical heads meet FIA race director Charlie Whiting on Friday to further discuss the new rules.
