I do agree with extending the floor forwards to push that CoP forward in conjunction with fans.
smaller front wing, yes agreed
another way to go is to ban underbody splitters
Agreed, but the CoP will be rearward of the driver, fans will just increase overall DF from the floor. Reducing the front wing might not help, as it will still be sensitive to the wash from the car in front. The FIA have tried small front wings, the last two seasons we have had oversize front wings, making them DF neutral is the way to go. If it doesn't produce DF then it can't be sensitive to the car in front.
whether the CoP is rearward of the driver or located in his vacinity is design issue for the engineers tunng the vehicle. As long as the underbody falls within prescribed dimensions i don't see an issue.
The rear wing should be incidence limited anyways to keep the DF down.
everywhere else I think we are on the same tack.
extending the floor forward will help position the CoP as well and certainly an incidence limited (not DF neutral) front wing would have benefit too.
Only advantage I can see to a DF neutral front wing would be to re position the air flow from the leading to be advantageous to the underbody of the following car. Could work....
What I like about fans is that it effectively fills in the wake behind the car while still providing Df to its own car. Sure that wake is a turbulent whirl but at lest there is density and pressure in that air. The engineers could then route all cooling outlets via the duct to improve air flow velocity through it.
ok heading off point and into detail design.... sorry.
Someone mentioned harder tyres to create a "wet" race scenario. That was the intention of the grooved tyres and it did not work because the cars were still sensitive to being in the wake of the leading car.
Its the sensitiveity to wake that need to be reduced.
you can achieve that through having a smaller wake. (fan car)
or a lower wake (incidence limited wing)
I also advocate manual sequential shift gearboxes because a driver making an error is part of the show and provides opportunities to overtake, which leads to the drama.
as for engines I'd also like to see 1.2L Turbo, 4 cyclinder petrol units with direct injection allowed and or a 2.0L turbo diesel with direct injection option. I just too a stab at an equivalence ratio, will have to work out what it actually should be.
