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.
