What single regulation would you implement

[Hawkmoon]

Freedom of engine design. No limits on number of cylinders, capacity or revs. Just pick normally aspirated or turbo and then let them loose.

[Mark]

I wouldn't even go that far. Give them a capacity limit and certain characteristics and ban the use of expensive materials, but engine development should be completely unrestricted.

I'd also go back to one engine per race.

[Rollo]

I would ban wings.
You would still be allowed to shape the bodywork to achieve downforce but I've always thought that they detract from the skill of close quarter racing.

Heck even the DRS by its existance admits that when it comes to drivers being able to get close to other cars, wings inhibit their ability to do so.
I know that you see far more tactics and racecraft in a Formula Ford race than you do in F1 for precisely this reason.

[52Paddy]

I'd take out the requirement for engines to be 2.4 V8s.

[vhatever]

I would ban all "push button, go faster" nonsense. This mario kart garbage with KERS/DRS has completely poisoned the well of F1.

Well dont watch it then

I liked the mid race refuelling, they should bring that back.

Oh, and get rid of team orders, they spoil everything.

And if a race is red flagged, the tyres cant be changed(Monaco).

I might ban DRS, but I've no problem with KERS. At least it's the same for everyone, whereas DRS has a bias.

agree, I see refueling gives F1 more drama, the race result and the whole race is more unpredictable, and during the pit stop, Massa may take the fuel hose to the track before completely released from the tank.

[wedge]

Easiest to fix is to get rid of the regulated rev limiters.

[ArrowsFA1]

Simple. I would like to see the regulations changed to ensure the cars had more power than grip. Aero has for far too long had far too greater an influence on the cars and this had let to gimmicks like KERS, DRS and tyres designed to "spice up" the racing, but as we see in the wet drivers with cars that have more power than grip can race without the need for those gimmicks.
