General Motors’ GMC division is best known for commercial vehicles and work trucks, but the 2023 Yukon is one of the most accommodating and luxurious passenger vehicles in the brand’s history. This large family SUV offers spacious accommodations across three rows of seats and is even offered with a longer wheelbase—called Yukon XL—that opens up even more space for cargo. Most models are powered by a V-8—either of a 5.3- or a 6.2-liter variety—but a turbo-diesel 3.0-liter inline-six is also available, a novelty in this segment. Towing capacity and acceleration are both strong with any of the available engines, but the V-8s aren’t particularly fuel efficient. The base SLE trim is hardly spartan, with a host of convenience and technology features offered as standard, but the upscale Denali trims luxe things up to compete with premium entrants such as the Cadillac Escalade and Lincoln Navigator. The Yukon’s biggest competitor, however, comes from sister brand Chevrolet in the form of the Tahoe and Suburban SUVs, both of which are mechanically identical and offer similar accoutrements for slightly less money.
