Karmann files for insolvency

Karmann, the century-old German coachbuilder synonymous with cabrios and the famous 1950s Karmann Ghia, has filed for insolvency. The company made the move Wednesday in Germany in response to a dramatic decline in revenue, an inability to pay for its massive layoff plan and the worldwide economic crisis. The North American operations, which make convertible tops for Detroit car companies and Volkswagen, are not affected, a spokesman said.

Audi RS7 Sportback refreshed with 190 mph top speed

Audi has fitted the RS7 Sportback with a series of mild styling changes only 18 months after its reveal at the 2013 Detroit auto show. Among the subtle visual modifications brought to the plush performance liftback is a lightly reworked front end. It features a restyled single-frame grille set within a slightly more structured bumper, bringing its appearance in line with less-powerful versions of the A7 Sportback revealed last week.

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.
