2027 vs 2026 GMC Sierra 1500: should you wait?
If you need a truck now and want confirmed pricing, get the 2026 Sierra 1500. If the redesign, new V8 engines, and bigger interior tech matter more than timing, it’s worth waiting for the 2027 model.

The 2027 Sierra 1500 brings a full redesign, two new V8 engines, and over 60 inches of combined displays, but GMC has not released pricing, and it isn’t expected until late 2026.
- Buy the 2026 if you need a truck now and want confirmed pricing.
- Wait for the 2027 if the redesign, new V8s, or bigger displays are the priority.
- Either way, check the invoice price before you negotiate.

What’s New for the 2027 GMC Sierra 1500?
GMC made several changes to the Sierra 1500 for the 2027 model year. This next-generation truck comes with a new exterior design and a revamped interior packed with luxurious materials and innovative features.
But the biggest highlights are the engine lineup and the interior tech. The 2027 Sierra offers an improved 2.7L TurboMax and 3.0L Turbo-Diesel from the outgoing model, but adds two new V8 options: a 5.7L and a 6.6L.
Inside, the new truck has more than 60 inches of combined screen space, with a 12.2-inch driver information center, a 16.3-inch center display, and an available 11.5-inch passenger touchscreen for media and entertainment.
The off-road-focused AT4X also gets new Multimatic Jounce Control Dampers and standard 35-inch tires, which improve traction and control in rough terrain.
2027 vs 2026 GMC Sierra 1500 Exterior Design
Familiar, Proven Look
The current-generation Sierra keeps the styling buyers already know from dealership lots today.
Bolder, More Vertical Design
A more vertical grille, bigger fenders, more hood contouring, new headlights, and updated taillights around the MultiPro tailgate give the redesigned truck a bolder, more muscular look.
Interior and Technology: The 2027 Sierra Gets the Bigger Upgrade
40+ Inches of Displays
The 2026 model offers more than 40 inches of combined displays, including a 12.3-inch driver screen and a 13.4-inch touchscreen up front.
60+ Inches, Plus a Passenger Screen
The 2027 Sierra adds a 12.2-inch driver display, a 16.3-inch center screen, and an available 11.5-inch passenger touchscreen not offered on the current truck. It also gains a reimagined interior with premium materials, a MultiPro Center Console, a panoramic sunroof, and a 16-speaker Bose system with headrest speakers.
Engine Options: New V8s for 2027
Four Known Powertrains
2.7L TurboMax four-cylinder (310 hp, 430 lb-ft), 5.3L V8 (355 hp, 383 lb-ft), 6.2L V8 (420 hp, 460 lb-ft), and 3.0L Duramax Turbo-Diesel (305 hp, 495 lb-ft), all paired with a 10-speed automatic.
Two New V8s, Output TBD
An enhanced 2.7L TurboMax, the same 3.0L Duramax, and two new V8s: a 5.7L and a 6.6L, also paired with a 10-speed automatic. GMC has not released official output figures yet, but says the 6.6L V8 will be the most powerful naturally aspirated V8 in its class.
Towing and Capability: What We Know So Far
Confirmed: Up to 13,300 lbs
When properly equipped, the 2026 Sierra 1500 can tow up to 13,300 lbs.
Not Yet Rated
The 2027 model has no official towing figures yet. But with the new V8s and the diesel engine retained, you can expect it to hold up well.
AT4X Comparison: Why Off-Road Buyers May Want to Wait
Current AT4X Setup
The current AT4X delivers GMC’s established off-road package, without the new damper and tire upgrades coming for 2027.
New Dampers, 35-Inch Tires
New Multimatic Jounce Control Dampers and standard 35-inch tires give the 2027 AT4X a clearer off-road upgrade story than the current model.
Denali and Denali Ultimate: Which Model Year Feels More Premium?
