The Porsche Panamera is scheduled to receive its first facelift for the 2013 model year. Test vehicles have been spotted by our spies over the past few months, but these latest spy shots confirm the model will receive a redesigned rear end.

Unfortunately we don't get to see much of the changes. A temporary makeshift bumper looks to have been grafted on to the rear, so we'll have to patiently wait to take a peak at final styling changes. However, the German sportscar brand aren't well known for massive redesigns on their models, generally favouring evolution rather than revolution.

The front end remains the same as we have seen in previous test vehicles. Large black panels hide some minor modifications to the headlights and the front fascia closely resembles the new Porsche 911 (991).

The range of engines is unlikely to change, although Porsche engineers will probably tweak a few minor details for improved performance and fuel economy figures.
