Mosley welcomes qualifying change

Qualifying will now take part in three phases, with five cars dropping out after a first 15-minute session and another five after a second stint. The remaining 10 will then fight for pole position in a 20-minute final session.

The current single-lap format had been heavily criticised.

"Everyone realised that television and live audience needed a better spectacle and they were not getting a better spectacle," said Mosley after the London meeting.

"There is a lot of different ways of doing it but this is the one that guaranteed the cars being out there.

"What they will probably do is run for the full 20 minutes, so they have the lightest possible fuel load, come in and put a set of tyres on right at the very end," Mosley added. "They start the last 20 minutes with whatever fuel they have chosen for the race.

"We will weigh the car before and then top up afterwards. The reason we are letting them top up is that it will encourage them to run, if we didn't let them run then they would just do one or two laps, this way they will do a lot of laps."

Mosley was not worried that the new format could prove complicated for television viewers and claimed the new system will prove climatic.

"Watching it on TV, they will see the slowest five gone, and then the next slowest five gone. And in the last 20 minutes the times will get quicker and quicker, and the fuel load will come down and then it will get really dramatic as the fuel load comes down and they put on new tyres and go for a time," he said.

"The only problem is that everyone will do their ultimate time in the last minute, they will aim to cross the line and start their lap just before the chequered flag goes. Instead of being anti-climatic it will be climatic and that will change the whole thing."
