Mosley reports F1 rules concensus

The rules that are to be tidied up are those concerning spare cars and post-qualifying engine changes from parc fermé. Henceforth the teams will be allowed to use any two chassis in the practice sessions, but must race the two that they qualify on Saturday (or start any replacement from the pit-lane). Cars whose engines have been changed because of mechanical failure must start the race from the back of the grid.

Mosley continued: "As to the future, the teams want to talk about the exact implementation of the single-engine rule, and they want to keep one-directional telemetry from car to pit. Most of them are quite keen to hang onto traction control and launch control. We [the FIA] are equally keen not to do that. We've agreed to have a major meeting about it in the future. I hope they'll come to agree with us within the next few weeks.

"There's a degree of agreement over standard components, and we've agreed to look very carefully at the standard rear wing - to investigate it, to make one and try it."
