The 2011 Mercedes SLK marks the third generation of this model and here we see new SLK spy shots. The big thing to concentrate on here is the metal roof mechanism which has been the defining characteristic of this model since it first appeared. Mercedes has dubbed the new technology Magic Sky Control which uses electrochromic glass (for more on electrochromism, see Wikipedia). Using this new technology the new Mercedes SLK will have a roof with a central glass panel as the main change for the updated model.
