The latest in a string of reports on Le Mans Series rule changes could stand to really shake things up in the prototype classes in a few years. ACO, the French racing organizers which coordinate the European Le Mans Series and its headline event, are reportedly planning on banning V10s and V12s from the top-tier LMP1 class by 2011.

In their place, LMP1 would adopt the rules currently in place for LMP2, which means 3.4-liter V8s and 2.0-liter turbos. LMP2, meanwhile, would switch exclusively to production-based engines. Both Audi and Peugeot, who have dominated the series with their 12-cylinder turbodiesels, are reportedly in favor of the change in formula despite the need to send their engine development programs back to the drawing board.

      I think I'd rather just see displacement limitations than cylinder count limitations, but I also think this could be interesting to really distinguish LMP1 and LMP2 again. With LMP2 being production-based engines, they'll be more prototypical in terms of chassis development. LMP1 can be both and maybe that will up the level of manufacturer commitment to the class?

      On another note, this doesn't indicate that there are different rules for Diesels and gas engines. I don't see any NA Diesel working out in racing, and I think a 2.0L displacement is too little for a turbo Diesel to compete. I could be wrong though.

      Presumably, finally privateers will be able to keep p in LMP1 with a Judd or Zytek V8 or an AER P07 or MZR-R I would imagine.

        A turbodiesel could be competitive at 2.0L theoretically, 3.0+L for sure, but I doubt the ACO will allow high enough boost so that they can get enough HP at low revs to be competitive with the high-revving gassers.

      That's surprising.

      It's good LMP2 is going to production-based motors because it seems that LMP1 is going to get expensive. Getting the kind of HP out of 3.4L NA or 2.0L turbo that LMP racing requires isn't a commonplace thing and so costs a few bucks.

      Using production-based motors has done great things for Grand Am prototypes, it'll be interesting to see how LMP2 does with this formula.

        The ALMS mazda LMP2 car is currently running a race version of the MZR engine that is in many mazda's these days, it will be interesting to see what other manufacturers decide to do.... will porsche go to a 6, or stick with the 8, and shrink it a bit from the Cayenne size?

        The more news that comes out about next year, the happier I am that I get to see the current class setups at Laguna Seca, and while I know the ALMS rules are different from Le Mans, the Le Mans rule changes will very likely affect the ALMS rules. Oh, uncertainty. It is the essence of motor racing, isn't it?

      Good move, maybe this will cause Audi to go back to FSI and not dominate... Oh wait. I'd hate to see the Audi TDI go, the noiseless stealth bomber R10 is amazing.

        Except that Audi dominated with the R8 FSI also...

        Diesel or standard Petruleum - Audi takes names!
