The GMC Yukon is a full-size, traditional SUV that’s based on the same platform underpinning General Motors’ large pickup trucks, including the GMC Sierra. This model was introduced in 1992 and is sold in 4x2 and 4x4 configurations. An extended wheelbase GMC Yukon XL is sold separately.
2015 to Present: GMC Yukon
One year after GM's large pickup trucks were updated, the GMC Yukon and the similar Chevrolet Tahoe were also revised. Rear-wheel drive is standard and four-wheel drive is available. Three trim levels are offered: SLE, SLT and an upscale Denali model.
The GMC Yukon is marked by an expansive, upright grille with three horizontal slats. An oversized headlamp assembly with LED daytime running lights, a muscular hood and a lower grille opening offset by fog lamps are additional distinctions up front. GMC embellishes the usual slab-sided body with upper and lower character lines and available retracting side steps. To the rear is a power liftgate, a liftgate spoiler and dual exhaust ports.
The fourth-generation Yukon is powered by an aluminum-block, 5.3-liter V8 engine making 355 horsepower and 383 pound-feet of torque, which is paired with a six-speed automatic transmission. This model is EPA-rated at 16/23 mpg city/highway. The Yukon Denali is equipped with a 6.2-liter V8 engine making 420 horsepower and 460 pound-feet of torque, which is paired with an eight-speed automatic transmission. This model is EPA-rated at 15/22 mpg city/highway.
SLE and SLT editions provide room for eight, or nine by replacing the front bucket seats with a bench seat. Standard equipment includes keyless entry, power accessories, a tilt-and-telescopic steering column, a Bose audio system, GMC's IntelliLink infotainment system, a 110-volt outlet, tri-zone climate control and GM's OnStar telematics system with a built-in Wi-Fi hot spot. Denali models bring in leather upholstery, heated and cooled front bucket seats, a power folding third-row seat and wireless charging for mobile devices.
Standard cargo volume measures 15.3 cubic feet behind the third-row seat, 57.6 cubic feet behind the second-row seat and 94.7 cubic feet with the second and third rows folded. Trailering capacity ranges from 6,300 to 8,300 pounds with the smaller engine and up to 8,400 pounds in the Denali.
Earlier GMC Yukon Models
The first-generation GMC Yukon was offered from 1992 to 1999. The second generation made its debut in 2000 and lasted through 2006, and the third-generation model was built from 2007 to 2014.
The first-generation Yukon included two- and four-door models through 1997. The two-door was a 4x4 only. The earliest models were powered by a 5.7-liter V8 engine paired with a five-speed manual or a four-speed automatic transmission.
The second-generation Yukon was powered by a 4.8-liter V8 engine paired with a four-speed automatic transmission. An available 5.3-liter V8 joined the line later. All Denali models offered a 6.0-liter V8 engine.
The third-generation Yukon started off with the two smaller V8 engines, but replaced the Denali's engine with one displacing at 6.2 liters. A six-speed automatic transmission became available starting with the 2009 model year. The 4.8-liter engine was dropped for the 2010 model year, with the 5.3-liter V8 now serving as the base engine.
