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 utilitarian G-Class. The GL-Class shares its basic platform with the ML-Class and R-Class.
The Mercedes-Benz GL-Class is large and capable off road yet feels surprisingly car-like on the road. That car-like feeling comes in part because it is 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 large travel trailer, but verify tongue weights and ratings before making decisions. All GL-Class models come with a seven-speed automatic transmission and four-wheel drive. All seat up to seven people.
