A very large SUV, the QX80 has a plush, luxurious, and quiet interior. We liked the supple ride but found this big barge to be ungainly, with cumbersome handling in everyday driving, although it was ultimately secure in emergency maneuvers. The seven-speed automatic and 400-hp, 5.6-liter V8 provide smooth and strong performance, but it chugs premium fuel and returned just 15 mpg overall. The tall step-up to the cabin makes climbing in or out an ungracious affair. Cargo volume is plentiful, and the small, power-folding third-row seat comes in handy to carry two kids. Electronic safety aids include blind-spot warning and rear automatic braking. The new Nissan Armada is essentially the same vehicle but costs less.
