The Car Connection's Take
TCC Rating

8.8
TCC’s Bottom Line
Infiniti's civilized the full-sized SUV about as well as Land Rover has--but does the world still need big utes like this one? With rugged styling, fairly nimble handling and diesel economy, the 2012 Mercedes-Benz GL-Class can charm the mud right off a Land Rover Range Rover.
