Hennessey tunes C7 Corvette Stingray

Hennessey Performance and its gang of Texas tuners are planning upgrades for the 2014 Chevrolet Stingray Corvette before the car even hits the market. We're sure Corvette engineers working on the next ZR1 are taking notice, presumably with a chip on their collective shoulders. In October, the Hennessey HPE700 Corvette is expected to debut packing a claimed 700 hp, with help from an Eaton TVS R2300 supercharger.

The Rolls Royce Phantom gets a tweak

Ever since BMW bought Rolls Royce, the company has been on the up. First we got the Phantom, which showed the world just how special a Rolls Royce of the 21st century could be. The Phantom spawned the Drophead Coupe and more recently the Phantom Coupe.

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.
