In just a few weeks' time, the second-gen
Mercedes-Benz GL will make its debut at the New York Auto Show. The 2013 GL-class SUV is based on the same architecture underpinning the new ML and will maintain three rows of seats. Improvements will naturally be made to fuel efficiency and refinement, while interior space is set to grow. Given it accounted for close to 40 percent of GL sales last year, an optional V6 diesel engine will be offered.
