Large and luxurious, the GL is built in the United States alongside the M-Class mid-size SUV and the R-Class touring wagon. The GL is designed to appeal to Mercedes-Benz sedan owners who want the off-road, four-wheel-drive, seven-passenger and 7500-pound towing capabilities that come with a full-size SUV along with the luxury and safety features they have in their other Mercedes vehicles.

While their names sound similar, don't confuse the new GL-Class with the venerable G-Class or Gelandewagen. The GL shares nothing in common with the utiliarian G-Class, which will remain part of the Mercedes model lineup.

Initially available in one form, the Mercedes-Benz GL 450 is large and capable off road yet feels surprisingly car-like on the road. That car-like feeling comes in part because this is the first full-size SUV built around a unibody architecture instead of traditional body-on-frame construction. Mercedes says the GL is strong enough to tow a 30-foot boat, a trailer carrying three horses, or a good-sized Airstream travel trailer.
