To combat the competition, Mercedes is adding a few cosmetic changes to the CLS as these disguised test mules reveal. The major change is a revised grille, similar to that seen on the larger CL coupe, while the rear end gets a new taillight design and bumper.
The facelifted CLS is expected to be displayed at September’s Frankfurt Motor Show with the first sales to start in early 2008. Follow the jump to see several images of the CLS mule undergoing cold weather testing in Europe.
