Why it stands out

The 2015 GMC Yukon XL stands out as a full-size SUV built around space, utility, and a more upscale feel than many buyers expect from something this large. It uses a traditional truck-based chassis with a solid rear axle, and its long-wheelbase design gives it more room for passengers and cargo than the regular Yukon. The third row folds flat, but the truck-like rear-end design leaves it with a higher cargo floor than car-based crossovers and the Ford Expedition.

For 2015, the Yukon XL SLE came standard with a 5.3L V8 engine, eight-passenger seating, 18-inch aluminum wheels, an eight-inch infotainment system screen, three-zone climate control, a Bose-branded audio system, and General Motors’ OnStar technology. A nine-passenger seating configuration was available, and the optional Driver Alert Package added forward collision alert with automatic emergency braking, lane-departure warning, lane keep assist, lane-change alert, and a vibrating safety alert seat. The SLT added the Driver Alert Package as standard equipment and brought in features such as a hands-free power liftgate, power adjustable pedals, a locking rear differential, a heated steering wheel, heated and ventilated front seats, heated second-row seats with power-folding functionality, and leather seating surfaces.

The Denali trim is the most luxurious expression of the 2015 GMC Yukon XL. It came with the larger 6.2L V8 engine, magnetic ride control suspension, 20-inch aluminum wheels, an upgraded Bose audio system, and a chrome grille, while the available Denali Touring Package added a sunroof, a head-up display, navigation, and a rear-seat entertainment system. That mix of room, comfort, and available upscale equipment is a big part of the Yukon XL’s appeal, though fuel economy is a clear drawback and the vehicle’s truck-based layout means it does not drive like a car-based crossover.
