Mercedes wants consumers to know they can still have the large. powerful cars Americans expect and still get good mileage.

On Sunday the Vision GL420 Bluetec concept was introduced at the North American International Auto Show. This 290hp, 515ft-lb. beast will still deliver 24mpg and an estimated 600 miles per tank. In comparison the gasser GL450 4.6L will get only 14 city/18hwy mpg.

To compliment its powerful engine will be a powerful look complete will 21in. wheels, fender flares and a revised grille.

Plans to release Bluetec versions of the R, ML, and GL model lines as early as 2008 are still in motion.
