It’s been a while since we brought you any news on the revised Porsche Panamera, but today the car has been caught during cold-weather testing. The prototype caught testing today dropped more of its camouflage, offering us a good look at the new rear lights.

The second-generation Panamera->ke1840 is still years away, so a slightly sleeker shape and different graphics on the current model freshen it up enough to keep us satisfied for the next few years. We have included a photo where you can compare the old and new design, but of course you'll need a keen eye to notice the differences.

It has also been rumored that the revised version of the Panamera will get a front end inspired by the Sport Turismo Concept, so our fingers are crossed!

Rumors also suggest that the updated 4S version will drop the current V-8 engine in favor new, twin-turbo, 3.0-liter V-6 engine that will deliver about 420 horsepower - an increase of 20 horsepower over the current model.
