My own feelings on this is that finding the right power to weight should be left relatively free, as it is up to us to work out how much lower is enough speed versus how little weight gives best handling. The track list should set the tone for that.
However I’m not sure where this leaves us in terms of safety requirements. A number? A system? Lighter cars and aluminium cars would be at a disadvantage (maybe rightfully so).
Or are we looking to establish a touring class of tournament where all vehicles ought to have a similar, narrow range of performance?
