Mosley: new regs remain unchanged

Mosley said: "There is agreement with all teams to continue with the procedures we have adopted at the beginning of the season and to continue with rules adopted last October. The only minor changes are that as far as the spare car is concerned, teams can use two cars in the various practice sessions but those used in Saturday qualifying have to be raced unless the team takes the spare car and starts from the pit lane.

"If there is an engine change (as McLaren and BAR were permitted in Brazil without penalty), the relevant car will start from the back of the grid," Mosley said. This avoids any controversy over whether or not the engine change was actually necessary.

Mosley admitted that most teams do not like the parc ferme rule, where cars are impounded on Saturday afternoon until the race, but this will continue until the teams can come up with a better solution to the problem of ensuring that the car that starts the race is identical to the one that finished qualifying, in terms of the amount of fuel, the specification and the set-up.
