Handling, step-in height.
The QX is a very large and plush full-sized SUV. It has a quiet cabin and a steady and supple ride, but handling is ungainly. The seven-speed automatic transmission and 400-hp 5.6-liter V8 provide smooth and strong performance but it gobbles premium fuel, returning just 15 mpg overall. The tall step-up into the cabin is an ungracious affair. Cargo volume is plentiful, and there's a usable third-row seat. Handling is cumbersome in everyday driving and doesn't shine at its limits. Electronic safety aids include lane-departure and blind-spot warning systems, and a panoramic rear-view camera.
