It seems like Porsche is working on an update for its Porsche cayenne despite the fact that it has not been around for more than a few years. It could be that they want it to coincide with the release of the Macan. These pictures indicate that the Cayenne will get a change in its front and rear look but it is hard to see what those changes might be.
It is expected that it may look rather like the 2014 Panamera at the front and may also have some of the same engine options that this model has. This could include the 3.0 liter twin turbo V6 and maybe the E-Hybrid. The guess is that it may be debuted so that it is ready for 2015, but with no official information, it is anyone’s guess really.
