2023 GMC Yukon XL Review

When you need to carry people, cargo and big toys, you need to look beyond today's crossover SUVs to a more robust full-size, truck-based SUV. The 2023 GMC Yukon XL is one of the biggest and most accommodating, an extended version of the standard Yukon with more third-row seat room, more cargo capacity, and a robust towing limit of 8,000 pounds.

This year, the Yukon XL adds a new Denali Ultimate trim level that lifts the plush Denali trim to new heights of decadence. Unique exterior trim, 22-inch wheels and upgraded leather are only a few of the special touches that push the Denali Ultimate to a starting price near $100,000. Also contributing to that sum is the Super Cruise semi-automated driving system, which allows for hands-free driving. The system works on roads mapped in a cloud-connected database — typically large divided highways or interstates — and can even change lanes by itself. The slick system first rolled out in Cadillac models and is available in 22 other General Motors models for 2023. Super Cruise comes standard on the Denali Ultimate and is optional for the regular Denali.

GMC positions the Yukon XL as a premium SUV, making it more expensive than its near twin, the Chevrolet Suburban, but less expensive than the related Cadillac Escalade. Choosing between the GMC and Chevy comes down to personal preferences because the two SUVs are nearly identical mechanically. Only the Denali and Denali Ultimate, with upgraded dash designs and leather, plus Super Cruise, stand apart from anything the Suburban can offer. The Ford Expedition Max and Jeep Wagoneer L are also worthy alternatives with higher towing limits than the Yukon XL.

The 2023 GMC Yukon XL is a full-size SUV that seats seven to nine passengers in three rows depending on the configuration. It's available in SLE, SLT, AT4, Denali and Denali Ultimate trim levels. A 5.3-liter V8 (355 horsepower, 383 lb-ft of torque) is standard on all but the Denali and Denali Unlimited, which get a 6.2-liter V8 (420 hp, 460 lb-ft). The larger V8 is also optional for the AT4 trim.
