The 2015 Porsche Cayenne was caught testing for the first time back in April and now, Porsche->ke1 engineers took it out for another testing session. This time around, our photographers caught it on public roads in Germany.

With most of the new 911 family out and official, the Boxster and Cayman fresh out of the box, and the Macan still under development, there is only one model left to work on: the Cayenne->ke212.

The second-generation Cayenne was unveiled back in 2010 and it still looks relatively fresh and young, but now Porsche has started to prepare a facelift to keep it fresh for the next couple of years.

The prototype caught testing today wears camouflage only in the parts that are going to be updated: bumper and lights up front, plus new slimmer-looking taillights and a changed rear bumper. The wheels will also receive a new design, and rumors suggest that there are some new engines in the works too.

Expect to see the revised Cayenne sometime in late 2014.

Even though the Cayenne is heavily camouflaged, we expect it to adopt some of the new Panamera style elements, which sounds good to us. This might help the Cayenne to "lighten" up a little and look more youthful in the process.

Up front, we will see a redesigned bumper and a new set of headlights to help give the face the needed update to keep it new looking. On the rear, the taillights will look slimmer, like the rest of the Porsche lineup, and the bumper will also be redesigned to better match the revised front end.

The model will also be offered with redesigned wheels and an updated interior.

All these changes were required because BMW has just revealed its all new X5 and the Mercedes ML is rather fresh, so the Cayenne needed to refresh. This refresh also aligns with its sister vehicles - the Volkswagen Touareg and Audi Q7 - revisions.
