2015 GMC Yukon XL Denali

The Yukon XL is GMC's biggest SUV, the long-wheelbase version of the Yukon that seats up to nine and tows serious weight. It drives like a big truck, with a commanding view of the road and a ride that soaks up bumps well on the highway. Inside, you get a roomy, well-built cabin with comfortable seats, though the materials in lower trims are more workhorse than luxury. The real reason to pick the XL over the regular Yukon is the extra space behind the third row, which swallows luggage for a full family trip. The Denali is the luxury pick for buyers who want a Yukon XL with a stronger engine and more standard features than the SLT. Its 6.2L V8 makes 420 horsepower and 460 lb-ft of torque, paired with the eight-speed automatic, so it has plenty of passing power even when towing. The Denali's standard Magnetic Ride Control gives it a smoother, more controlled ride than the other trims, especially on rough pavement.
