Panamera Sport Turismo Concept made its official debut at the 2012 Paris Auto Show and now Porsche->ke1 has unveiled a new video presenting the design process behind this exclusive concept car.

In this video you will be watching designers Michael Mauer and Mitja Borkert to Porsche's R&D center in Weissach. They are explaining the development process of the Panamera Sport Turismo. You will learn about every step needed to transform a clay model into the concept you have seen in Paris.

As a reminder, the Panamera Sport Turismo Concept is powered by a plug-in hybrid drivetrain that delivers a total of 428 horsepower and allows the concept to go from zero to 62 mph in less than six seconds. It can be driven in pure electric mode up to a speed of 80 mph and can cover distances of over 18 miles. But before you'll get to excited you have to know Porsche has no intention in offering a production version of this concept.
