GMC introduced the next-generation of its flagship SUVs, the 2021 GMC Yukon and Yukon XL, enhanced by offering class-leading technology and elevated by precisely-engineered capability.

"GMC Yukon is the full-size premium SUV that's made to be used," said Duncan Aldred, vice president of Global Buick and GMC. "The new Yukon delivers what customers value most - premium features, purposeful technology and all-terrain capability."

The 2021 Yukon lineup is headlined by an all-new and more upscale Denali and the first-ever GMC 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.

Elevating Capability with Active Response 4WDTM System and Advanced Chassis Controls

The heart of the new GMC 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. Coupled with the new multilink independent rear suspension, the Yukon offers the ride sophistication and isolating characteristics typically associated with smaller vehicles but scaled for the capability requirements of GMC's full-size SUV customers.

The available four-corner Air Ride Adaptive Suspension offers ride-height adjustments of up to 4 inches (100 mm) total, as well as an automatic self-leveling feature. Drivers can raise the body up to 2 inches (50 mm) for additional ground clearance when driving off-road.

In higher speed highway driving, the system automatically lowers Yukon's ride height ¾ inch (20 mm) to improve aerodynamics and fuel efficiency. A driver-selectable setting enacts a 2-inch (50 mm) drop to aid passenger entry and exit when the vehicle is parked. The self-leveling feature helps with comfort and control, particularly when the vehicle is loaded with cargo and when trailering.

Magnetic Ride Control, a technology pioneered on exotic sports cars, enables both precise body control and handling capability. It is one of the fastest-reacting damping systems in the industry, using sensors to continually read the road and alter the damping rate of the shocks almost instantly. It reacts much faster than traditional shock absorbers to reduce bouncing, body roll and vibrations that can often resonate in a large SUV.

The available electronic Limited Slip Differential manages torque laterally across the vehicle for increased confidence on the road. The eLSD has the ability to preemptively manage axle torque and vehicle behavior based upon multiple vehicle inputs. If wheelslip is detected on either side, eLSD reacts quickly to shift power to the wheel with better traction. With cues taken from sports cars, the eLSD offers unmatched handling characteristics with an improved level of performance not seen before in a full-size SUV. On the GMC Yukon, this new eLSD has the ability to engage the differential, offering the capability customers need in a more refined package. In 4WD LO, the eLSD operates at locking torque to prevent wheelslip in off-road conditions.

These technologies utilize performance car engineering to expand the bandwidth of the premium full-size SUV to deliver a wider array of all-terrain capabilities, secure performance in adverse weather and confidence in everyday driving.

Class-Leading Power and Interior Space

GMC 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.

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. Yukon and Yukon XL are expected to be the most fuel-efficient full-size SUVs with the Duramax 3.0L turbo-diesel engine.

Gains in Interior Space

Long renowned for its substantial interior capacity, the 2021 GMC Yukon grows even more in terms of usable space for customers. With a nearly 5-inch-longer (127 mm) wheelbase and 6.1 inch (155 mm) increase in overall length compared to the current model, it offers 41 percent more third-row legroom and 66 percent greater cargo volume behind the third row.

On the GMC Yukon, space gain is achieved efficiently - the increase in overall length is less than 3 percent, while maximum cargo room increases by 30 percent. Yukon XL retains its crown as GMC's roomiest SUV for both passengers and cargo, benefitting from a 4.1 inch (104 mm) increase in wheelbase. The result is an increase in both passenger and cargo space, with only a fractional change (less than 1%) to Yukon XL's overall length. Both vehicles now have a lower, flatter cargo-loading floor allowing easier access to cargo space.

On both vehicles, access to the third row is easier than ever, thanks to new sliding second-row seats that improve ingress and egress. The second-row seat can slide 5.5 inches (140 mm), a first for Yukon passengers.
