I would see no reason to doubt that claim. After all it is the same engine with the 8 speed transmission that is in the '13 T-egg (240 hp) and that is a TDI from the VA(P)G parts bin -- no matter what Porsche chooses to call it. Apparently Porsche has chosen to use the drive train straight across from both the diesel and hybrid offerings from their stablemates at VW in the Cayenne. The gas V6, while still a basic VW, has been "breathed upon" by the Porsche engineers a bit. Mike of course would know for sure.
Whoa... stand by for an attack from the "Badge" crowd...true as your comments are..
