The 2021 GMC Yukon will adopt very similar updates to the Chevy models, starting with the new T1 truck platform the SUVs share with the Silverado and Sierra full-size pickups. The new platform allows them to grow in size significantly and pack more tech and highly-automated driving assistance systems.

Expect the same highlights such as the standard multi-link independent rear suspension, optional 277 HP Duramax 3.0-liter inline-six turbodiesel, available Air Ride Adaptive Suspension, and 10-inch infotainment system.

The GMC Yukon and Yukon XL will make no secret of their kinship with the Tahoe and Suburban, featuring identical footprint and proportions. These latest spy shots give us the best idea yet of the finished item as the prototype drops the car cover camouflage for tightly-wrapped tape. This allows us to see the design of the front and rear ends for the first time.


As before, the big GMC SUV will adopt front and rear designs typical of the brand and, judging from the posh grille featured on this prototype and the quad tailpipes, we believe it’s the high-end Denali trim which comes with the 420 HP 6.2-liter V8 as standard.

It’s also pretty clear that the full-LED headlights and taillights are in production trim. The front end is obviously inspired by the all-new GMC Sierra truck, including the shape of the headlights, grille and fog lights. The 2021 GMC Yukon and Yukon XL will debut on January 14, 2020 at a special event in Vail, Colorado.
