The premiere of the new SL-Class roadster from Mercedes-Benz is scheduled to take place at January's Detroit Motor Show, with the first official photos and details on the model due to be issued by the end of December this year. The new 'Sport Leicht' will be the first to feature an entirely revised chassis based on an extensive use of lightweight materials, which follows the trail of the current SLS AMG platform and will also make it onto the next generation of supercars to be produced in Affalterbach.
