Why it stands out

The 2021 GMC Yukon XL stands out as a full-size SUV that combines serious space with a more modern ride than earlier versions. It debuted for the 2021 model year with more than a foot added between the front and rear axles, which increased passenger room and cargo capacity. It also switched to an independent rear suspension, a change that improved ride and handling while helping create a more comfortable third row and additional cargo space. An optional power sliding center console that could move fore and aft up to 10 inches added a clever touch of flexibility.

The 2021 GMC Yukon XL also offered a broad range of equipment and powertrains. A 5.3L V8 engine was standard, while a 6.2L V8 engine and a 3.0L Duramax turbo-diesel engine were optional. Standard features on the SLE included a 10.2-inch touchscreen infotainment system with wireless Apple CarPlay and Android Auto compatibility, eight-passenger seating, and automatic emergency braking with forward-collision warning. Higher trims added more comfort and convenience, including heated and ventilated front seats, leather seating surfaces, a power liftgate, and available second-row bucket seats. The AT4 brought off-road hardware such as four-wheel drive, skid plates, front recovery hooks, and all-terrain tires, while the Denali added a 420 horsepower 6.2L V8 engine and a 14-speaker Bose audio system.

For buyers, the appeal is straightforward: the 2021 GMC Yukon XL is built for families or anyone who needs abundant space without giving up upscale features. It can be configured for seven, eight, or nine passengers, and its available diesel engine is especially attractive to those who want better fuel economy. The tradeoffs are the ones expected of a vehicle this size, including poor fuel economy and handling that trails car-based crossovers.
