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 the 6.2L V8, Magnetic Ride Control, and a much plusher interior with ventilated front seats and a head-up display. Under the hood is the 6.2L V8 making 420 horsepower, paired with an eight-speed automatic and four-wheel drive; it moves the big SUV with authority, and the EPA rates it at 16 mpg combined. The Denali's standard Magnetic Ride Control and auto-leveling suspension smooth out the ride, even when you're towing near the Yukon XL's 8,400-pound maximum.
