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.

GM to build Cadillacs outside the U.S.

General Motors CEO Dan Akerson said Tuesday that the company plans to begin building Cadillacs outside the United States by the end of 2012 as part of its plan to make GM's premium brand a true global nameplate. Akerson said overseas Cadillac production would reduce the risk of foreign-currency fluctuations and allow GM to better manage its supply chain. Although Cadillac long has been sold in China and other international markets, it's produced only in North America.
