Mercedes-Benz reveals first C-class details

Mercedes-Benz has revealed limited details about its new fourth-generation C-class sedan, more than two months before it is due to make its world debut at the Detroit auto show. Although the new BMW 3-series and Audi A4 rival is yet to official unveiled -- in fact, all we have so far are interior renderings -- Mercedes-Benz says the new C-class will be a significantly more advanced car than its predecessor in terms of construction, with a “best in class” weight figure and a level of structural integrity that it describes as being “unparalleled” in its class. Among its features is a new lightweight body structure that uses a newly developed aluminum hybrid construction process that Mercedes-Benz claims will shave as much as 220 pounds over the current model depending on the engine it uses.
