Porsche->ke1 is already preparing a facelift for the Panamera luxury sedan. The car has been caught testing many times, but this time the car was caught testing with almost no camouflage. Our spy photographers caught both standard and Turbo version, so you can easily see the changes featured on both models.

As you can see, the revised Panamera will receive new headlamps and taillights, plus redesigned front and rear bumpers. Porsche will also redesign the interior with improved materials and new technologies.

We expect some upgrades regarding the engine and transmission, so you can expect the new Panamera to deliver improved fuel economy and better performance. Rumors suggest that the 4S version will drop the current V-8 engine in favor of a twin-turbo 3.0-liter V-6 engine that will deliver about 420 horsepower - an increase of 20 horsepower over the current model.

We expect the new Porsche Panamera to be unveiled in April 2013.
