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. "It always presents a special challenge when we develop a new kind of car for the Porsche brand," says Mauer, "precisely because we haven't been in the segment before, and the question of whether it matches the Porsche brand always looms in the background." 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.

Nissan Juke R takes to the track on video

The road-legal Nissan Juke R may never be built, but today Nissan showed off its the GT-R-powered Juke performing on track.  It's a madcap one-off Juke pepped up with the GT-R's 523bhp 3.8-litre twin-turbo V6. The video below was recorded at the MIRA track in Warwickshire, as engineers had a chance to fine-tune the chassis.

Chevrolet Sonic

The Sonic is Chevrolet's latest attempt to induce a small car in the American market and take on the Ford Fiesta in one fell swoop. Replacing the generally unaccepted Aveo, the Sonic draws from a youthful and aggressive design in a bid to appeal to the younger market. Available as a four-door sedan (seen here) as well as a five-door hatchback, the Sonic displays a 'progressive exterior design', according to the American brand's press materials.
