As well as that, the FIA wants an overhaul of car regulations too. The governing body has made no secret of the fact that it believes a standard chassis would be the best way of reducing costs and improving the show.
"We believe that a standard chassis is the best solution," wrote Mosley in his letter. "The competition would then be between drivers armed with rival, fuel-efficient drive trains but otherwise in equal cars. Painted differently and with different sponsors, the cars would look as different as they do today to anyone but an expert.
"But if the teams want to continue to make individual chassis, we need some proposals which really do meet the four agreed objectives of road-relevance, safety, cost reduction and improving the show. We also need to ensure the survival of the independent teams."
Mosley acknowledges that teams are unlikely to accept plans to adopt a standard chassis, but he believes that only a radical alternative solution will be of any benefit.
"One example of radical change would be to permit moveable aerodynamic devices," added Mosley.
"Immense time and effort is currently going into making bodywork which moves enough to enhance performance, however slightly, but not enough to excite the interest of the regulator or rival teams. This is not satisfactory; it is wasteful, expensive, ultimately pointless and contrary to sporting fairness.
"With moveable aero devices, both active and passive, designers would have an incentive to build a car which the driver could adjust to optimise performance when following another car. This would facilitate wheel-to-wheel racing.
