Formula 1 engineers moving towards rules package

The Formula 1 engineers have managed to come up with a package of rule changes which they say will cut lap times by three seconds per lap, the target which FIA boss Max Mosley wanted them to achieve this year. Our understanding is that the engineers are proposing two fundamental changes: a reduction in the size of the rear diffuser which will reduce overall downforce by around 25%, although the engineers reckon that with current rates of development that figure will be reduced to 18% before the start of the 2005 season.

In addition the engineers are suggesting that F1 adopt the suggestions put forward by the tyre companies to reduce the number of tyres available for two sets per weekend.
