A barely disguised prototype of the 2015 Porsche Cayenne facelift was spied undergoing testing ahead of an imminent official launch.

This is our best look at the refreshed Cayenne as a light grey prototype was spotted wearing camouflage only on the taillights which will be derived from the smaller Macan. The front fascia has received a redesigned bumper together with an updated grille and altered headlights while the daytime running lights have also gone through a minor revision.

Expect some light changes on the inside as well while under the hood of the Cayenne S there will probably be a twin-turbo V6 3.0-liter with 420 bhp (313 kW) and 384 lb-ft (520 Nm). Porsche could also be planning an E-Hybrid version that will combine a V6 3.0-liter with an electric motor to provide a total output of 416 bhp (310 kW) and 435 lb-ft (589 Nm).

Since the prototype was wearing very little camo, expect a full reveal in the following weeks.
