Using the old engine.

Chris Harris meets Porsche R&D chief - PistonHeads

Q: Lovely RSR photos just shown. Is it true that the RSR and Cup car will usethe old Mezger engine and not the new DFI motor?

A:[Grimacing] "I know where the photos were taken and I don't know how they did it. We want to participate next year [the next day Manthey were announced as running factory 991 RSRs at Le Mans 2013] and, yes, the RSR and Cup will use the old engine. It is very reliable and strong and it does a good job and in the Cup it will be 3.8 litres. It was an easy decision."

 

Maybe it's doing a shaker version of Sebring, but that's definitely not at Sebring.

 

Ha. Got me...
