If you want to get spy shots of vehicles that will soon be showing up in European dealerships, the place to be every year from December to March is the area near the Arctic Circle in Sweden.

We've all seen stills of the Panamera on the Nordschliefe, but now you can see (and hear) the car in full motion video.
