Like its Chevrolet Suburban sibling the massive Yukon XL can seat up to nine (though eight-place seating is more usual), tow a heavy trailer, and swallow more cargo than can most minivans. Handling is commendable for such a large vehicle, though parking can be awkward. Other strengths include comfortable seating and a quiet, well-controlled ride. The XL's standard 5.3-liter V8 is powerful but a similar Suburban that we tested delivered only 13 mpg overall. Models equipped with this engine either meet Ultra-Low Emissions Vehicle (ULEV) guidelines or can use cleaner-burning ethanol-content fuels. A 335-hp, 6.0-liter V8, full-time AWD, and stability control are standard on the uplevel Denali.
