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.
The new 2021 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 of ground clearance. When at this maximum height, the Yukon AT4 offers a nearly 32-degree approach angle for added off-road capability.
The heart of the new Yukon is its all-new Active Response 4WDTM System, a combination of technical systems including: auto two-speed transfer case, Traction Select, chassis controls and a new electronic Limited Slip Differential.
Magnetic Ride Control enables both precise body control and handling capability. It reacts much faster than traditional shock absorbers to reduce bouncing, body roll and vibrations that can often resonate in a large SUV.
Yukon and Yukon XL drivers 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. The standard engine is an all-new 5.3L V8.
Yukon's propulsion lineup expands for 2021, as drivers can also select an available 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.
