As this is a mid-cycle refresh, don't expect a wholesale change for the car. There's light camouflage covering the front and rear fascias. The new front end looks like it's straight off the CLS, with a low, four-sided grille and sharp LED accents in the headlights. It looks decidedly different than the C-Class and S-Class, a common complaint about the current car. The profile looks relatively the same, though the rear, too, gets updated lighting. The camouflage makes it seem like the lights haven't changed, but through the netting you can see slimmer LED units.
No word on when we'll see the updated model, but look for more news in March or April around the Geneva Motor Show or New York Auto Show. If not then, the car may debut at Frankfurt in the fall.
