A prototype of the upcoming 2021 GMC Yukon XL Denali has been spied while testing by our spy photographers.
Admittedly, the prototype in question is bathed in camouflage and, thus, it is difficult to discern all the areas that have been altered from the outgoing model.
That being said, it does appear as though this test car is equipped with the front grille that will adorn the finished item and looks somewhat similar in design to the current Sierra Denali. A number of other design changes, which inevitably are present, aren’t visible through the camo.
Sitting beneath the skin of the new Yukon XL Denali, as well as lesser versions, will be the GM T1 platform utilized by pickup trucks and body-on-frame SUVs. This architecture is currently used by the 2019 Chevrolet Silverado and 2019 GMC Sierra and replaces the old K2. It will eventually underpin other GM products as well, such as the Chevrolet Tahoe and Suburban as well as the next-generation Cadillac Escalade.
It remains to be seen what engines GM will offer with the updated Yukon range, but the T1 platform offers support for a series of 4.3, 5.3 and 6.2-liter petrol engines with six and eight cylinders. Additionally, it supports various Duramax turbo diesels.
Finally, the new underpinnings will also allow GM’s designers to create a brand new interior, which should be more modern and feature the latest tech, such as a new infotainment and various luxury and safety systems.
