For many automakers becomes very difficult to keep secret information about their future updates as long as they are not fully prepared to appear before the public.
The same happened with the German automaker Mercedes, whose information brochure on the new SL cars flowed through the World Wide Web users to share Autoblog.nl. On the scanned pages shows Mercedes SL model series in 2013 in all sorts of angles and with a demonstration of the cabin. The model looks very elegant and luxurious, that suggests the imminent appearance of a top of the Mercedes without binding AMG.
We also know that SL will be somewhat lighter than its predecessor. Only unknown future engine lineup roadster. We can only guess that they may become outdated eight-cylinder motor with a possible twelve-cylinder.
