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? Lavish and large, the 2012 Lincoln Navigator is luxury, American-style, but its powertrains are a step behind those of the competition. 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.
