Three Sierra Trims Worth a Closer Look
Sierra shoppers who place a premium on design, comfort and technology will want to spend extra time comparing GMC's higher-end trim choices. Denali, SLT and AT4 each offer a different personality, giving you an opportunity to choose a Sierra that feels right for your driving style.
Denali
Luxury with signature GMC style. The Sierra Denali pairs distinctive exterior design with a premium cabin, Denali-exclusive interior details, heated and ventilated front seats, a panoramic sunroof and Super Cruise hands-free driver assistance technology. For 2027, GMC lists Denali with a Denali Premium Suspension with Adaptive Ride Control and a 15-inch diagonal multicolor Head-Up Display.
SLT
A premium Sierra option. SLT has traditionally been positioned as a well-equipped premium trim, making it an appealing choice for shoppers who want upgraded comfort and technology without necessarily moving to Denali. Because GMC's current published 2027 Sierra 1500 lineup does not list SLT, availability should be confirmed with Royal Buick GMC when comparing model years.
AT4
Premium style with an adventurous edge. The 2027 Sierra 1500 AT4 adds distinctive design, a factory-installed 2-inch lift, 34-inch all-terrain tires, 12-way power front seats and standard Super Cruise with trailering capability. It is an excellent choice for shoppers who want upscale features with a more rugged personality.
Discover a More Refined Sierra 1500
Denali has become synonymous with GMC's premium design philosophy, and the 2027 Sierra 1500 takes that idea further. The new Denali features an exclusive interior with three available colorways, 12-way power heated and ventilated front seats, a panoramic sunroof, a 15-inch Head-Up Display and 20-inch painted pearl nickel aluminum wheels.
For shoppers seeking even more, Denali Ultimate adds upgraded 14-way power heated and ventilated front seats with massage, a 16-speaker Bose Premium Series audio system, a passenger display and 22-inch wheels.
