Honda reportedly plans electric car for '15

Honda could be joining the growing ranks of electric-car makers and reportedly plans to sell one in the United States sometime around 2015. Reports in the Nikkei Business Daily in Japan say that the car would arrive then as part of Honda's plans to meet stricter mileage standards set to take effect for the 2016 model year. The car would be Honda's answer to the Nissan Leaf and the Chevrolet Volt, which have announced eye-popping mpg figures and are due next year.

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.
