Year to year, it's often tough to spot the minor changes made to models, needing to park them side by side to spot the differences. Such is the case with the 2015 Porsche Cayenne. Our spy shooter in Europe got these shots of the 2015 Cayenne almost completely uncovered. At first glance, it would be easy to think that no changes have been made. Indeed, the changes are minor, but they are there. The front LED turn signal and driving light strip has essentially been flipped, with the tapered edge now at the bottom instead of the top.

The outer intercooler openings in the bumper are more square than on the current model, and the center grille opening appears to be larger. Around back, there doesn't appear to be any major changes. The quad exhaust outlets on this de-badged model suggest it's a Turbo, compared to the dual rectangular outlets of the non-turbo Cayenne models.

Although not seen on this tester, a plug-in hybrid option is expected to come for the Cayenne in 2015, using the 3.0L supercharged V-6 and inline electric motor sandwiched between the motor and the transmission from the non-plugin Cayenne Hybrid as a starting point. Expected to share much of its hardware with the recently introduced Panamera S E-Hybrid, it should be able to travel at highway speeds on solely electric power and have an all-electric range of more than 10 miles.
