The Automobile Club de l'Ouest (ACO) and FIA have outlined plans to cap the number of constructors eligible to provide LMP2 class entries.
ACO president Pierre Fillon said costs could drop by "20 per cent", believing the crackdown will be in line with reducing costs when new regulations begin in 2017 with a view to curbing running costs rather than purchasing equipment at a capped price – as was the case with the LMP3 initiative.
An initial target cost of €500,000 has been pencilled in for a rolling chassis (without engine).
A single engine supplier will be nominated for the World Endurance Championship and the European and Asian Le Mans Series, however multiple engine manufacturers will be granted to supply teams competing in the United SportsCar Championship in 2017.
Full details on the new LMP2 class rules will be announced during Le Mans week, however an initial statement from the ACO read:
"With the number of different chassis currently available to customer teams - some manufacturers supplying just one or two cars - the cost per car is far higher than for, say, a manufacturer supplying 10 cars to several teams.
"By limiting the number of manufacturers, the business case is far more sustainable for the supply of cars, plus teams will receive a better quality product with lower associated maintenance and operational costs."
