New Porsche CEO Michael Macht evidently wants more overall victories, and while Volkswagen will soon control Porsche, family member Ferdinand Piech is chairman of VW's supervisory board. With the resources of the group available, Porsche could develop a new car to go for number one. No timetable has been given, but this actually wouldn't be the first time that there has been an internal battle at Le Mans. Earlier in the decade, Bentley also ran a prototype coupe based on the Audi R8.
With the interest in promoting alternatives like diesel at Le Mans and Porsche soon to debut a hybrid, a prototype with a similar system is not beyond the realm of possibility.
