Redesigned Mercedes-Benz M-class takes to the road for testing

Mercedes-Benz gave its M-class SUV a mild freshening last year. But a more-thorough makeover is on the way two years from now for the 2012 model.

These prototypes--the first we've seen of the new M-class--are wearing a lot of camouflage, but through the nose opening we spy a sharper grille design that looks similar to the GLK.

We also see some styling changes in the door area. And the addition of LED headlights is likely--most of Mercedes' competitors in Europe are moving in that direction.

Mercedes engineers are focused on getting some weight out of the new M-class, in response to tougher fuel economy and emission standards. Look for the powertrain lineup to stay pretty much the same. But a hybrid is likely to join the mix.

The new M-class should be in showrooms in summer 2011.
