What Changed

The SLK roadster enters its third generation for 2012. The new model is roughly the same size increasing by only about an inch in length and width. A vertical front grille and more pronounced hood define the new styling. The SLK retains its hard top convertible, although a new feature adds a glass roof with the ability to block the light. Mercedes offers the US model with either a 1.8l four-cylinder engine (SLK250) or a 3.5l V6 (SLK350). A six-speed manual is standard on the SLK250, with a seven-speed automatic optional. The seven-speed automatic is standard on the SLK350.
