Mosley to hasten changes

In April Mosley announced a number of changes that were designed to reduce the sport's costs and make the sport more accessible to new teams. These included longer-life engines to last for at least two races, a reduction in aero performance and the use of just two sets of tyres per race weekend.

The FIA is within its rights to impose changes from 2008, the date the existing Concorde Agreement, which governs the sport, expires. But following a number of high-speed accidents including Ralf Schumacher's smash at Indy last weekend, Mosley wants teams to accept measures before that.

The teams have so far failed to agree on the changes leading Mosley to threaten to use Article 7.5 of the Concorde Agreement for the first time. This article was introduced following the death of Ayrton Senna 10 years ago and gives the FIA the right to force through changes on safety grounds.

"Formula 1's technical working group has been saying for more than two years that engine power needs to be reduced," Mosley was quoted as saying in The Daily Telegraph. "We have seen with Massa and Ralf Schumacher that speeds in F1 are dangerously fast. We have to act now.

"I expect dissent. Article 7.5 is a way of applying pressure. If the teams can't come up with the required changes, we will," Mosley added.

According to reports, team bosses are to meet next Monday (28 June) and will be given two months by the FIA to come up with their own proposals. If they fail to reach an agreement the FIA will put forward three options and allow a further 45 days for teams to choose or else have the changes imposed on them.
