LMP Future Regulations (was Le Mans EVO rules - now hypercar rules)

CTD · 23 Jun 2008, 09:52 (Ref:2235536)

Hello.
Im getting pretty confused with these "new" EVO rules which was going to rule in 2010!
Are they thrown in the bin, are they "on hold", or are they going to count in 2010?.
I've tried to read about it here on Ten-Tenths but also on other forums, and im just confused, so if someone just could say whats counting i would be happy!

The EVO rules are in a constant state of evolution

ie nobody knows yet!

dont think the new rules are 'EVO' just new rules all together.

EVO meanin an evolution of the current LMP1 rules. The 2010 rule changes should be out in October this year.

a very general out line was released during the LM24 at the ACO press conference.

Evo regs are a variation on current P1 regs for manufactuers who would prefare a look closer to a road car.

The aero hit a P1 Evo car would take over a regular P1, with no pretense to looking like a roadcar, will be compensated by restrictor/weight etc. breaks.

I think Audi is the only manufacturer to prefer open top prototypes, although they don't have any roadcar looking anything close to that

I believe that with it being fairly obvious recently that the closed top prototypes are significantly faster than the open tops, Audis preference may change very quickly...

At one point (iirc) Mr. Clarke said Acura intended on building an open car for P1, but that may have changed. who knows not much more info has come out of HPD regarding next season's plans. Maybe by October when teams begin to tease us with possible futre plans we will know something

I don't think closed tops are necessarily faster than open tops. It was just that Peugeot desperately wanted to win Le Mans this year and they did all they could. The R10 wasn't conceived for such huge steps from one year to the next in its development as Audi were used to the developing pace of the private opponents they mainly had so far (in 2000, BMW didn't further develop the LMR, Cadillac wasn't strong enough, Bentley was still Audi

etc.). But I do think Audi could build from scratch an open top to run just as fast and well as the 908.

I read that the maximum temperature in the cockpit will be 32 degrees. Isn't it 25 at the moment? Why will ACO raise the temperature?

Over one lap certainly, but over a race distance the distinction isn't as clear. The LM24 proved that running a closed Coupe, has it's own set of disadvantages to deal with.

Speculations of the new rules starting up again?

CTD · 24 Jun 2008, 11:54 (Ref:2236480)

Is it realistic that the new rules will demand Gt looking cars for P1?, because i don't think the top Prototype class should be shut down!

It's not just Pugeot that I am referring to. The Charouz Lola Aston and the Dome S102 outpaced the open cars right out of the gate. I am no aerodynamicist, but I would be highly inclined to believe that there is a big advantage in downforce created by the windscreen and top of a closed top car. Likewise, I would be inclined to believe that the design is inherently better in a straight line. Anyone with an advanced knowledge of aerodynamics feel free to correct me if I am wrong.
