Mercedes’ (@mbusa) top of the line SUV, the 7-passenger GL (#2013GL-Class), is new for 2013. As the top selling premium luxury sport utility vehicle, GL certainly is a healthy profit contributor to parent company Daimler AG. Built at Mercedes-Benz Tuscaloosa, Alabama assembly plant, 53% of GL production is sold in the United States. The 2013 GL is the second generation GL and continues to be derived from the platform that also underpins the 5-passenger ML. About 80% of the GL is all new for its second generation. We had a chance to drive several versions of the new GL at its global press preview in Santa Fe, New Mexico.
