The Porsche Panamera facelift was spied recently at a gas station in Stuttgart, Germany. The three prototypes caught on camera are not camouflaged and show various design changes. It appears that the Panamera facelift is going to have new headlights and LED DRLs, re-designed taillights, and slightly modified front and rear bumpers. The date of its launch has not been announced. However, these Porsche Panamera prototypes seem to be in the latest stages of development. This means that we could have a new version of the Panamera by the end of this year.
