2027 GMC Sierra 1500: 2027-Present Guide
The 2027 GMC Sierra 1500 is the newest version of GMC's half-ton pickup, redesigned inside and out and on sale from late 2026. It brings two new V8s, a stronger 2.7 turbo, a 10-speed automatic on every engine and a 16.3-inch center screen. Here's what's new, how the engines and trims line up, and what to know before you buy one of the first trucks.

What's New on the 2027 Sierra 1500
GMC calls this the next-generation Sierra 1500, and almost everything you see and touch is new. The front end borrows the slim lighting look of the Sierra EV, while the cabin gets a 16.3-inch center screen, a 12.2-inch driver display and an available 11.5-inch passenger screen. In addition, the Sierra gets its own articulating center screen that hides a storage cubby, something the Chevy Silverado doesn't offer.
Under the hood, the 5.3 and 6.2 V8s are gone. In their place, GM's sixth-generation small-block brings a 402-hp 5.7-liter V8 and a 481-hp 6.6-liter V8, while the 2.7-liter TurboMax climbs to 350 hp. The 3.0-liter Duramax diesel carries over at 305 hp and 495 lb-ft, and every engine now uses a 10-speed automatic.
The trim lineup is simpler, too. SLE and SLT are gone, so Elevation now sits in the middle between the Pro work truck and the AT4, AT4X, Denali and Denali Ultimate. Crew Cabs come first, while Regular Cab and Double Cab trucks follow as production grows.

- 16.3 inCenter screen
- 10-speedEvery engine
What we like
- Two new V8s and a stronger 2.7 turbo
- Huge screens and Super Cruise on most trims
- Diesel offers 900-plus miles of highway range, per GM
What to watch
- First-year design with all-new V8s
- The 6.6 V8 tows and carries much less than the 5.7
- Prices are up, and CarbonPro bed is gone
2027 GMC Sierra 1500 Engines and Power
All four engines drive through a 10-speed automatic, with 2WD or 4WD. The big surprise is towing: the top 6.6 V8 is only rated for 9,400 lb because it comes on heavy luxury trims, so the 5.7 is the one to get if you tow a lot.
| Engine | Years | Found in | Output |
|---|---|---|---|
| 2.7L TurboMax I4 | 2027– | Pro, Elevation | 350 hp / 455 lb-ft |
| 5.7L V8 | 2027– | Pro, Elevation (opt.); AT4, Denali | 402 hp / 428 lb-ft |
| 6.6L V8 | 2027– | AT4X, Denali (opt.); Denali Ultimate | 481 hp / 501 lb-ft |
| 3.0L Duramax I6 diesel | 2027– | AT4X; optional on all other trims | 305 hp / 495 lb-ft |
Brand-new for 2027
2027 Sierra 1500 Launch Timeline
This generation is brand-new, so there's no year-by-year history yet. Instead, here's how the launch has rolled out so far, and we'll add yearly changes as GMC announces them.
- Jun 2026 GMC previews the next-generation 2027 Sierra 1500, a week after Chevy shows the 2027 Silverado.
- Sep 2026 GMC publishes full specs and Crew Cab pricing, from $51,295 for a Pro 4WD to $87,895 for a Denali Ultimate.
- Oct 2026 Production starts at GM's Silao, Mexico, plant with Crew Cabs.
- Late 2026 GMC says the first trucks reach dealers before the end of the year.
- Early 2027 Fort Wayne Assembly in Indiana is due to switch over to the new truck, while Regular Cab and Double Cab models follow as production expands.
Our verdict: if you can wait, let the first few months of production go by. Then you'll have EPA numbers, the other cab styles and a clearer picture of early recalls.
2027 GMC Sierra 1500 Special Models
GMC kept its off-road and luxury flagships for the new truck, and gave the AT4X something it never had before: 35-inch tires.
2027–
AT4X
35-in tires Front and rear lockers Diesel or 6.6 V8
The AT4X gets 35-inch Goodyear Wrangler Territory MT tires, a 2-inch lift, Multimatic dampers, front and rear e-lockers and a Baja drive mode. Inside, you get a panoramic roof and 16-speaker Bose audio.
Later in 2027
AT4X AEV Edition
AEV bumpers Skid plates 18-in wheels
A package for the AT4X that adds AEV bumpers, skid plates, recovery hooks and 18-inch beadlock-capable wheels. GMC lists it as coming later in the model year.
2027–
Denali Ultimate
481-hp 6.6 V8 15-in head-up display Power steps
The top Sierra gets the 6.6 V8 as standard, with the diesel optional. It also adds a 15-inch multicolor head-up display, more than 60 inches of combined screens, power-retractable steps and Super Cruise.
2027 GMC Sierra 1500 Recalls
As of November 6, 2026, NHTSA lists no safety recalls for the 2027 Sierra 1500. That's normal for a truck that just went into production, so check again before you buy, and run the VIN once you have one. One older campaign, 26V114 (an electronic owner's manual that wasn't set to download), was filed against a range of 2025–2027 GM models, so a dealer can confirm whether it applies to a specific truck.
2027 GMC Sierra 1500 Safety Ratings by Region
The 2027 Sierra 1500 is too new to have crash-test results. GMC does say it adds 12 new standard safety features, including intersection automatic emergency braking, front pedestrian and bicyclist braking, reverse automatic braking and blind zone steering assist.
| Region | Program | Rating | What it means |
|---|---|---|---|
| United States | NHTSA | Not rated yet | NHTSA hadn't published star ratings for the 2027 Sierra 1500 as of November 2026. |
| United States | IIHS | Not rated yet | IIHS hadn't tested the new truck yet. The previous Sierra never earned a Top Safety Pick. |
| Canada | NHTSA and IIHS | Not rated yet | Canada doesn't run its own crash-star program, so Canadian buyers use the US results once they're out. |
| Middle East | None | Not rated | GMC sells the Sierra in the region, but there's no regional crash-test program. |
| Europe, Australia | Euro NCAP, ANCAP | Not rated | GMC doesn't sell the Sierra 1500 officially in these markets. |
Check back. Once NHTSA and IIHS test the 2027 truck, scores from the 2019–2026 Sierra won't carry over, because it's a new structure and IIHS has toughened its tests since then.
Buying a Used 2027 GMC Sierra 1500
Buying a 2027 Sierra 1500 means buying a first-year truck with two brand-new V8s, so a little patience can pay off. Still, there's a lot to like if you pick the right setup.
- Pick the engine for your trailer. If you tow heavy, the 5.7 V8 (up to 13,500 lb) or the diesel (12,100 lb) makes more sense than the 6.6, which is rated for 9,400 lb and about 1,450 lb of Crew Cab payload.
- Watch for early fixes. New engines and a new platform often get early recalls and service bulletins, so check NHTSA by VIN and ask the dealer about updates.
- Know what's missing. The CarbonPro carbon-fiber bed and the SLE and SLT trims are gone. Elevation is the new middle trim, so compare its features with the old SLT before you trade in.
- Wait for full pricing if you want a smaller cab. Only Crew Cab pricing was out at launch, and Regular Cab and Double Cab trucks come later.
Our picks
- Best overall: Elevation with the 5.7 V8
- Best for towing: 5.7 V8 with Max Trailering
- Best for long trips: any trim with the 3.0 Duramax
Think twice
- The 6.6 V8 if you tow heavy trailers
- Paying over sticker for an early truck
- Skipping the VIN recall check
