GMC Yukon Denali

Yukon Denali at a glance

The Yukon is GMC's version of the Chevrolet Tahoe, and the Denali sits at the top of the range with more powerful engines, richer equipment and distinctive styling. When the Cadillac Escalade arrived in 1999, it looked almost identical to the Yukon Denali, apart from its badges and grille, before the two models moved apart in later generations. GMC's other models, such as the GMC Sierra pickup and the electric GMC Hummer EV, are in the GMC catalogue.

First and second generations (1998–2006)

GMC introduced the Yukon Denali for 1998 as GM's flagship SUV. It shared the Yukon's body but had new front bodywork, lower cladding and a Bose sound system with cassette and CD changer. For 2001 the Denali was redesigned together with the Escalade, gaining a 6.0-litre Vortec 6000 V8 shared with the Sierra Denali pickup, a distinctive "punch" grille, six-spoke 17-inch wheels and heated second-row seats. From 2003, heated captain's chairs became standard in the second row.

Third generation (GMT900, 2007–2014)

The 2007 Denali used the 6.2-litre Vortec 6200 V8, also fitted to the Cadillac Escalade, rated at 301 kW (403 hp) for 2009. The six-speed 6L80 automatic replaced the older four-speed, and a power-tilt steering wheel became standard on the 2009 Denali.

Fourth generation (K2XX, 2015–2020)

Launched for the 2015 model year, the fourth Yukon gave the Denali an exclusive engine at first: the 6.2-litre EcoTec3 V8. An eight-speed automatic arrived during 2015, and from 2018 the Denali received a ten-speed automatic. Third-generation Magnetic Ride Control and active noise cancellation were standard. According to the old 1cars text, the Denali has 20-inch wheels as standard, with 22-inch wheels optional, a Bose audio system, heated and cooled leather seats, an 8-inch touchscreen with navigation and a power tailgate with adjustable height. The body uses a high proportion of high-strength steel, and the old 1cars text quotes a kerb weight of about 2,730 kg.

Fifth generation (T1XX, from 2021)

The fifth-generation Denali was revealed in January 2020 with its own dashboard design, and the new Yukon went on sale as a 2021 model in July 2020. Its wheelbase grew by 4.9 inches (124 mm), and the regular Yukon is 5,334 mm long.

All engines use a ten-speed automatic. The top suspension combines air springs with magnetic-ride dampers. The 2025 facelift, which entered production in November 2024, added the Denali Ultimate and AT4 Ultimate trims, new towing technology and 20-inch wheels as the minimum size. GMC also announced Yukon Denali and Denali Ultimate models for China in November 2024.

Yukon Denali XL: the long-wheelbase version

Alongside the standard model, GMC offers the long Yukon XL, and the Denali trim is available on both. According to the old 1cars text, the 2015 Yukon XL Denali is about 35 cm longer than the standard Denali, which gives a more usable third row and a much larger luggage area behind it. The same source quotes up to about 2.7 m³ of load space with the rear seats folded and lists a 110-volt power socket among the standard equipment. The XL suits large families and owners who tow a caravan or boat, while the standard Yukon Denali is easier to park and manoeuvre in town.

Rivals: how the Yukon Denali compares

The Yukon Denali competes with full-size luxury SUVs such as the Lincoln Navigator, the Ford Expedition Platinum and its own relative, the Cadillac Escalade. Its strengths are powerful V8 and diesel engines, a large cabin with three rows, high towing capacity and rich equipment. Its weaknesses are its size and weight and high fuel consumption with the V8.
