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

[JAG]

Is it feasable Lola, ORECA, Zytek and OAK/Pescarolo will carry over existing tubs until they are forced out by reg changes such as stricter crash test requirements?

With so many old chassis out in the wild there's a potentially large market for upgrading existing cars, particularly P2 were there isn't an arms race against manufactuers.

that's the 2nd time this weak i'm reading something on ten-tenths about different crash test requirements... but why and how do LMP1 crash standards differ from LMP2 standards?

[JAG]

I don't know if there are different requirements, I was using it as an example.

If current tubs are upto the job why wouldn't Lola and such continue to use the same basic design for the forseable future and update everything else?

In the 956/962 days Porsche must have been busy servicing and updating these cars as well as producing all new chassis for the best part of a decade.

Seems a good business model for a customer chassis manufactuer.

Because P-1s reach a higher terminal velocity and their engine/drivetrain (usually) weigh more. In an impact there is more force at the impact site and more inertia developed by the drivetrain, so higher crush rates are standard for P-1. But that does not mean that P-2 tubs will not pass P-1 testing, in fact several P-2 tubs already meet P-1 testing standards as the tub is the same in both models/chassis.

thanks
I hope they don't lower the LMP1 crash standards now that the new P1 engines are basically the P2 engines of old? Seems to me the more safety the better... Also I'd hope that even P2-only chassis would be built with excess safety in mind => able to withstand P1 crash tests...

That would be awsome but seems to me that the days when a private team buys a chassis and builds around him a new aero are gone.

I honestly do not mind the name of the categories of Le Mans, but i think that despite the environmental and safety concerns, the primal category in Le Mans should comply with the long straights and not take forever to go through them.
these straights will suffer when there are cars less then 320 km/h, please do not make them suffer

I was thinking more along the lines of buying the manufactuers updates as RML have done with Lola.

Pretty much all of the Lola and Courage P1/P2's built in the last five years could be updated to 2011 spec.

Seems there is much topic for discussion in here.

How about you sum it up.

As far as I'm concerned it's-

-Current P2 Chassis ballasted to 900kg

-460bhp+ production engine

-No hybrid system

-LMPC can be upgraded to ORECA 03

Am i reading the rules right if i think it's only allowed to have a supercharged diesel, not a turbo charged one??? (art 5.1)

Can any of the engine guru's on here shine a light on that?

What could be the reasoning behind this?

edit,

This could be a simple printing error, as it seems the difference isn't their in the French text

[HORNDAWG]

Yes, much topic for discussion!

Turbos are seen in technical regulations as a form of supercharging. End of story.

[HORNDAWG]

Audi should let the R-8 V-10 LMS be raced in GT-1 and build a GT-3 (variant/model) contender with a 3.2L turbo V-6.

That was part of my confusion, in the English text they are mentioned separately (and accidentally left out at the diesel engines), where as in the French text they are not separated.
