ACO rules changes for 2007 (apply to Le Mans, ALMS & LMS) - details -
"The LM P2 and GT2 categories are reserved mainly for private teams and must have performances inferior to those in LM P1 and LM GT1" (our emphasis)
LMP1- 81 litre tank for diesels (10% penalty - is that enough?)
LMP2- 5% smaller restrictor, also "...gap of 1.5% between the best LM P1 and LM P2 laps times must be respected"
No mention of electric hybrid power - so no new Zytek
