These photos suggest not to expect any significant changes in styling for the refreshed SLK. The lower portion of the front bumper has a single center opening, and the grille gets the latest iteration of Mercedes' single-bar design. The camouflage offers more concealment at the rear, but there's clearly something to hide. The exhausts are better incorporated in the shape, as well.
Mercedes is also expected to update the SLK's powertrains with the refresh into the SLC. There could be an AMG Sport version to slot between the regular model and full-bore AMG. Like the C450 AMG Sport, this one might use the brand's 3.0-liter, twin-turbo V6 with 362 horsepower.
