Full-size Pickup
The Sierra is mechanically identical to the Chevrolet Silverado — same chassis, same engines, same body — but trimmed and badged differently to chase the higher-end buyer. The Denali trim is the headline; the Denali Ultimate (2022-) added a sliding panoramic moonroof, tan-and-black 'Alpine Umber' interior with open-pore wood, and a tailgate that does six different motorized configurations. The AT4X and AT4X AEV are the off-road specials. Functionally a Silverado but with the interior of a Cadillac.
