The Flagship
2027 Sierra 1500 Denali Ultimate
The Denali Ultimate is the most luxurious Sierra ever, with a standard sixth-generation 6.6L V8 (the most powerful naturally aspirated V8 in its class), a class-leading screen layout, forged wood interior accents, and a standard three-year Super Cruise subscription with trailering.

Off-Road Flagship
2027 Sierra 1500 AT4X
The 2027 AT4X is the most off-road-capable Sierra GMC has ever built. New hardware includes 35-inch Goodyear Wrangler Territory MT tires (a Sierra first), Multimatic Jounce Control Dampers tuned for high-speed off-road impacts, and front and rear e-locking differentials. That e-locker combination is not offered by any competitor in this class. A 2-inch suspension lift, exclusive hood design, and reworked front fascia give the AT4X a more purposeful stance. Inside, an exclusive Timber Mahogany colorway pairs with a sport flat-bottom steering wheel, enhanced front seat bolstering, and a standard panoramic sunroof. The AEV Edition package returns for buyers who want to push capability even further.

Engineered to Work
Powertrain and Capability
The 2027 Sierra 1500 pairs four precision-engineered powertrains with a 10-speed automatic. Two all-new V8 gas engines lead the lineup: the 5.7L V8 and the 6.6L V8, the most powerful naturally aspirated V8 in its class. The class-exclusive Duramax 3.0L Turbo-Diesel returns for buyers who want efficiency and torque, and the enhanced TurboMax 2.7L delivers best-in-class standard torque. For Tampa Bay owners towing boats to the coast or hauling for work, that range means there is a Sierra built for the job. For the confirmed-vs-estimated numbers on every engine, see our 2027 Sierra 1500 engine guide.
Ambition without limits. Available Super Cruise with trailering supports hands-free driving across more than 600,000 miles of compatible roads.
Two All-New V8 Engines
The available 6.6L V8 is the most powerful naturally aspirated V8 in its class, joined by a strong, capable 5.7L V8. No other competitor in the class offers an available diesel, and the Duramax 3.0L Turbo-Diesel continues for the 2027 Sierra.
New Multimatic Jounce Control Dampers
On the AT4X, new Multimatic Jounce Control Dampers add stability and control on the road and keep the truck composed over extreme terrain. Paired with 35-inch MT tires, front and rear e-lockers, and a 2-inch lift, the AT4X is the most off-road-capable Sierra ever built.
Inside the Cabin
A Class-Leading Interior Built Around Three Screens
Every 2027 Sierra trim gets a redesigned interior. The centerpiece is a triple-screen layout anchored by a 16.3-inch articulating infotainment display with hidden storage behind it, a 12.2-inch driver display, and an available 11.5-inch front passenger screen with an articulating cover. Combined, that adds up to more than 60 inches of digital real estate, the most in the class. The new MultiPro center console folds flat into a stable work surface and houses USB charge ports below. Real wood is available, forged wood is standard on Denali Ultimate, and a panoramic sunroof is standard on AT4X and available on Denali Ultimate. Get the screen-by-screen and trim-by-trim breakdown on our 2027 Sierra 1500 interior and technology page.

The Redesign
What Makes the 2027 Sierra 1500 a Big Deal
The current Sierra 1500 launched as a 2019 model and received a significant mid-cycle refresh for 2022. The 2027 model year is the first ground-up redesign in nearly a decade. It shares its updated GM full-size truck architecture with the next-generation Chevrolet Silverado 1500. For Tampa-area truck buyers, that means two clear paths: the 2026 Sierra 1500 closes out a proven generation with known pricing and in-stock availability, and the 2027 brings new V8 power, a new interior, and a redesigned exterior with confirmed trim lineup. Heavy-duty shoppers: the Sierra 2500HD and 3500HD are expected to carry over unchanged for 2027, with their redesign reported for 2028. Full timing and details are on our 2027 Sierra HD page.

2019
Fourth Generation (Current)
The current Sierra 1500 debuted the MultiPro tailgate, CarbonPro bed, available 3.0L Duramax diesel, and 15-inch head-up display on Denali. A 2022 refresh added the AT4X off-road trim and Super Cruise.
