2013 Mercedes-Benz GL-Class Technical Data

The Mercedes GL offers a 121″ generous wheelbase that reaffirms the on-road comfort of this vehicle

The all-new 2013 Mercedes-Benz GL-Class that debuted at the New York Auto Show is leading the luxury full-size SUV market with new innovations including standard COLLISION PREVENTION ASSIST (CPA), Crosswind Stabilization, self-leveling air suspension and electromechanical steering.  The goal:  to increase active safety. More new features include assistance systems like Active Lane Keeping Assist and Active Blind Spot Assist, as well as PARKTRONIC with Active Parking Assist and the Surround View camera.

With benchmark performance and ride characteristics both on-road and in rugged terrain, the GL-Class cradles its occupants with the first-class comfort of a luxurious sedan. Its balanced proportions (length 201.6 inches, width 84.3 inches, height 72.8 inches) and generous wheelbase (121 inches) reaffirm the on-road comfort of this vehicle. At the same time, the short overhangs in the front and rear as well as substantial ground clearance serve to remind of its off-road capabilities.

From a design standpoint, the high SUV waistline with a distinctive chrome strip, the dynamic sweep of the character line and the chrome edging around the windows all add to the refined look of the all-new GL. The standard wheels on the GL350 BlueTEC and GL450 are 19-inch twin five-spoke alloys, while the GL550 comes with 21-inch AMG twin 5-spoke wheels. Twenty inch 10-spoke alloys are available as options on the GL350 BlueTEC and GL450.

This, together with ample space for up to seven passengers and a host of efficiency measures designed to deliver a substantial improvement in fuel economy, make the GL the perfect Mercedes model for larger families. The 2013 GL-Class goes on sale in the U.S. in September 2012.
