Video: The Porsche Panamera Sport Turismo concept build process

Porsche has released a video featuring Style Director Michael Mauer charting the design process of the Panamera Sport Turismo concept. The 10-minute YouTube video, which also features General Manager Advanced Design Style Mitja Rorkert, follows the build process through each modeling phase right up until the presentation of the show car at this year's Paris motor show.

We were impressed at the Panamera Sport Turismo concept's unveiling, particularly with its stance and detail execution, so the video is a chance to see just how this concept came into being.
