The popular Explorer is roomy and quiet, and has a livable third-row seat, but overall it trails more modern competitors. Handling is ungainly, lacking agility but the SUV remains under control when pushed to its limits. The ride is compliant but the body tends to move about often rather than get settled after hitting bumpy pavement. The 3.5-liter V6 engine, powering most versions, is powerful but rather noisy and not fuel efficient at 18 mpg overall in our tests. The Sport version gets a turbocharged V6 that is quieter and makes the Explorer quicker.
