Why it stands out

The 2020 GMC Yukon XL stands out as a full-size SUV built around space, utility, and traditional truck-based toughness. It rides on a solid rear axle and uses a higher cargo-area floor than car-based crossovers, which reflects its old-school layout and helps explain why it appeals to buyers who need serious passenger and cargo capacity rather than crossover-like packaging. The Yukon XL’s long-wheelbase design also gives it more room inside than the regular Yukon, especially for third-row passengers and luggage behind them.

For 2020, the Yukon XL SLE came standard with a 5.3L V8 engine, eight-passenger seating, an eight-inch infotainment screen, three-zone climate control, a Bose audio system, and 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 brought more comfort and convenience, including 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 is the most upscale version in this generation and gives the Yukon XL a more premium personality. It came standard 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 Denali Touring Package added a sunroof, a head-up display, navigation, and a rear-seat entertainment system. That combination makes the 2020 Yukon XL especially appealing to shoppers who want a large SUV that can do family duty, tow and haul, and still offer a genuinely luxurious cabin. Its main drawbacks are the ones that come with the territory: poor fuel economy, handling that trails car-based crossovers, and older technology compared with newer designs.
