Work continues on the all-new Porsche Panamera set to adopt an evolutionary design but with a significantly sleeker rear end enhanced by the longer and more sloped roofline. The final design should show some styling cues sourced from the rather appealing Panamera Sport Turismo concept introduced in 2012 but the Panamera's silhouette will still remain instantly recognizable.

Aside from getting a new look, the 2016 Panamera will make the switch to the MSB platform which could enable a diet of up to 200 lbs (91 kg) thanks to more extensive use of high-strength steels and aluminum. Also on the menu are Porsche's newly developed V6 and V8 engines which will be offered with rear- and all-wheel drive layouts.

The overhauled Porsche Panamera will be introduced sometime in 2016 and could go on sale as a 2017MY.
