2017 GMC Yukon XL Denali

The 2017 Yukon XL is GMC's full-size SUV, the longer version of the regular Yukon with extra cargo space behind the third row. It drives like a big SUV, with a commanding view of the road and a ride that soaks up bumps well, though you'll feel its size in tight spots. Inside, the cabin feels upscale for a workhorse SUV, with quality materials and available features like heated and cooled seats and a power liftgate. The XL's main draw is its cavernous interior, with room for up to nine people and a cargo hold that swallows luggage for a full family trip. The Denali sits above the SLE and SLT trims, adding a more powerful engine and a higher level of standard luxury. Its 6.2L V8 makes 420 horsepower and 460 lb-ft of torque, paired with an eight-speed automatic that shifts smoothly; expect 17 mpg combined. The Denali's standard Magnetic Ride Control keeps the big SUV composed on rough pavement, though you'll still feel its heft in corners.
