The 2021 Yukon lineup is headlined by an all-new and more upscale Denali and the first-ever Yukon AT4, taking Yukon into the premium off-road space. Yukon reaches a higher level of precise craftsmanship and premium accommodations through a combination of advanced features and class-leading technologies.

3.0L Duramax Turbo-Diesel Engine

Yukon and Yukon XL drivers will have their choice among three engine options, highlighted by an all-new version of the lauded 6.2L V8 engine, delivering 420 horsepower and 460 lb-ft of torque, more than any competitor. The standard engine is an all-new 5.3L V8. The 5.3L and 6.2L engines feature stop/start technology and new Dynamic Fuel Management that enables the engine to operate on two to eight cylinders, depending on demand, to optimize power and efficiency.

Drivers can also select an all-new 3.0L inline-six turbo-diesel engine. The new diesel builds on GMC’s expertise with Duramax turbo-diesels offered in Sierra, Sierra HD and Canyon models. All three engines are paired with a 10-speed automatic transmission and GMC’s Electronic Precision Shift push-button gear selector. Yukon and Yukon XL are expected to be the most fuel-efficient full-size SUVs with the Duramax 3.0L turbo-diesel engine.

2021 GMC Yukon AT4

Yukon AT4 provides premium off-road inspired design cues to match its strong capability. The first-ever Yukon AT4 features a unique front fascia that both visually carries the rugged all-terrain look and supports off-road capability. Coupled with the available four-corner Air Ride Adaptive Suspension, the AT4 can raise and offer an additional 2 inches (50 mm) of ground clearance. When at this maximum height, the Yukon AT4 offers a nearly 32-degree approach angle for added off-road capability. AT4 provides a contrast to Denali’s chrome-oriented look around the exterior, with trim characterized by body color or dark accents throughout, as well as a pair of red recovery hooks, similar to the Sierra AT4.
