Porsche 911 cabriolet: First official photographs

Porsche has developed an innovative fabric and composite-plastic folding roof for the 911 cabriolet as part of a push to give it a cleaner appearance, improved aerodynamic efficiency and greater levels of refinement than its strong-selling predecessor. Pictured here officially for the first time ahead of its world premiere in January at the Detroit auto show, the new open-top 911 is planned to go on sale in North America in 2012 in Carrera cabriolet and Carrera S models. Eschewing the traditional multilayered fabric structure of the 997 series 911 cabriolet, the next model (991 series) adopts a specially developed lightweight roof that uses two fabric-skinned composite plastic panels for the upper and rear part of the structure, giving it a more uniform shape together with a tauter fit that is claimed to make it more resistant than before to buffeting at high speeds.

Video: Buick Invicta

General Motor's Buick brand is blossoming in China, so the automaker chose the largest Chinese Auto Show this year to unveil its latest concept: the Invicta. Unlike the Riviera concept shown in Shanghai last year, the Invicta is slated for production soon given the level of refinement we saw when we viewed the car in Beijing. And unlike some market-specific new cars unveiled at the show, the Invicta will make its way to other markets across the globe. Click on the image on the left to see a video of the development and the designers who worked on the Invicta concept car.

New Mercedes A45 AMG has 105 years of 4WD on its side

With the new Mercedes A45 AMG on the horizon – complete with 4WD – Mercedes chart the history of all wheel drive on their vehicles. We tend to think of 4WD road cars as a modern innovation, and certainly very few 4WD road cars hit the road in a mainstream way much before the 1980s (the Jensen FF was hardly mainstream before someone points out that was in the 1960s). But the history of 4WD goes back, certainly in the case of Mercedes, a surprising 105 years when Daimler built the Dernburg-Wagen, a 4WD vehicle that not only got all-wheel drive but all wheel steering too.
