Racecar Engineering is reporting that there are plans to change the rules of the LMP1 Class of the FIA World Endurance Championship to allow for the new generation of Formula 1 engines that will be introduced that year. This means that Ferrari, Mercedes, Renault and PURE may all be able to find customers in sports car racing, and by the same token, there may be manufacturers who want to in sports car racing, who will leap on the opportunity to enter F1 with the same engine. The rules will increase maximum normally-aspirated engine capacity from 3.7-litres to 5-litres, but there will be restrictions on the fuel flow, which will force manufacturers to aim for more efficient engines. This might result in F1 teams using sports cars as test beds for their engines, which would be no bad thing for the WEC series.
Racecar Engineering says that the plans will be finalised in the next few days, with an announcement being made prior to the start of the Le Mans 24 Hours next Sunday.
