When GMC brass saw the sky-high take rate for its Denali-badged models, the hunt was on for a new sub-brand to further boost sales and margins. After they finished counting their cash, that is.

Which brings us to today. AT4, a recently introduced runner-up trim that blends much of the content and coddling of a Denali with varying levels of off-road improvement, was just revealed on the Iowa-class-sized GMC Yukon and Yukon XL for 2021 — a day after unveiling the upcoming Canyon. It’s already in place on the Sierra and Sierra HD pickups (appearing for 2019), as well as the 2020 Acadia crossover.

On Wednesday, General Motors’ truck division completed the AT4 sweep.
