The 2014 Mercedes-Benz GL-Class ranks 2 out of 10 Luxury Large SUVs. This ranking is based on our analysis of published reviews and test drives of the Mercedes-Benz GL-Class, as well as reliability and safety data.
Reviewers agree that the 2014 Mercedes-Benz GL-Class is very well-rounded, with a comfortable ride, a strong and fuel-efficient diesel base engine and an opulent interior.
Most test drivers agree that the GL350 is the best GL-Class trim for most consumers. It has the lowest base price of the model lineup, and test drivers say its turbodiesel V6 engine has ample power and torque. The GL450, GL550 and GL63 AMG each offer a twin-turbo, gas-powered V8 engine. Test drivers agree the GL450 accelerates quickly, and add that the performance of the other two trims is even more impressive. A seven-speed automatic transmission is standard with all engines, and most reviewers agree that it shifts smoothly and quickly. Fuel economy is up to an EPA-estimated 19/26 mpg city/highway in the diesel-powered GL350, which is very good for the class. The V8-powered GL450 is rated at 14/19 mpg, which is comparable to the fuel economy of other V8-powered SUVs in the class. Test drivers report that the GL-Class has a comfortable and composed ride over rough roads, though some critics find it hard to push the GL-Class through fast turns. The GL-Class also earns praise for it strong brakes and precise steering.
The Mercedes-Benz GL-Class' cabin is constructed with top-notch materials, according to test drivers. They say the seven-seat GL-Class' front seats are all-day comfortable and that the middle row offers plenty of legroom. As is typical of the class, the third row receives mixed reviews, as some testers note that it isn't comfortable on long trips for anyone other than kids. The GL-Class also offers a good amount of cargo space for the class. Mercedes-Benz fits every GL-Class with dual-zone automatic climate control, a rearview camera and its COMAND infotainment system, which controls most stereo and phone functions. Some reviewers report that COMAND is intuitive and works well, while others have difficulty making some stereo adjustments. Options include a 13-speaker Harman Kardon audio system, tri-zone automatic climate control, blind spot monitoring and a surround view camera system, which uses multiple cameras to give the driver a view all around the GL-Class to aid low-speed maneuvering such as parking.
