2027 GMC Sierra 1500 News: What To Expect

2027 GMC Sierra 1500 Specs: Turbo-Diesel & V-8 Engine Options

Under the hood of the next-generation Sierra 1500, you'll find one of four engines, depending on your trim level. The standard 2.7-liter TurboMax four-cylinder engine for the Pro and Elevation trims boasts a new turbocharger that raises its output to a responsive 350 horsepower and 455 pound-feet of torque while remaining efficient. If you want added range, choose the class-exclusive Duramax 3.0-liter turbo-diesel unit, which is standard with the AT4X and available for all other trims.

The two new naturally aspirated V-8 options – the 5.7-liter and 6.6-liter V-8s – have the highest Sierra 1500 towing specs and horsepower for this year, respectively. The 5.7-liter engine is standard with the AT4 and Denali (available for Pro and Elevation tiers), while the 6.6-liter V-8 comes with the range-topping Denali Ultimate and can be optioned with the Denali and AT4X.

All four powertrains pair with a 10-speed automatic transmission to help the miles melt behind you.

• Dark Ridge Metallic

Inside the cabin, you'll get a sneak peek at the future of luxury trucks, and it's memorable at every glance. Brand-new materials, like genuine forged wood trim for the Denali Ultimate, and colorways designed to guide your eyes to the newly available MultiPro center console and standard 16.3-inch touchscreen.

Summary

• The Sierra 1500 is designed to look taller.

The New Sierra 1500 Lineup: What Trims Do You Have Access To?

There are six 2027 GMC Sierra 1500 trim levels to choose from:

• Pro: Standard, but far from familiar. Immediate access to the 16.3-inch central touchscreen makes this trim exciting. And, with the 2027 Sierra column shifter tag speculation going around, it's possible that a new steering system is being implemented.
• Elevation: The second-level trim adds first-in-class articulation and hidden storage to the central display, ¹ dual wireless charging, and the new MultiPro center console. Elevation vs. Denali trim levels comparison shows how surprisingly close Sierra trims can be in terms of comfort.
• AT4: Introducing the flat-bottomed 2027 GMC Sierra steering wheel, the AT4 is the trim of choice for off-road capability. A 2-inch lift, 34-inch tires, and an auto-locking rear differential help you across any terrain while relaxing ventilated front seats.
• Denali: A 15-inch diagonal multicolor Head-Up Display helps you keep your eyes on the road, while the panoramic sunroof lets you enjoy natural lighting. Every ride is smooth, thanks to a Denali Premium Suspension with adaptive ride control.
• AT4X: Conquer any trail with Multimatic jounce control dampers, all-new Baja Drive Mode, and new underbody camera views as you enjoy a 16-speaker Bose® sound system with segment-exclusive headrest speakers. ¹ You co-pilot can help navigate thanks to a largest-in-class 11.5-inch passenger display. ¹
• Denali Ultimate: Climb in with MultiPro power steps, relax in 14-way massaging front seats, and get a crystal-clear view through an 8.5-inch Rear Camera Mirror as you reverse. 22-inch diamond-cut wheels add a high-end appearance.

Summary

• The 2027 lineup has six trims.
• The Pro and Elevation models feature a huge amount of screen space, including a 16.3-inch central screen.
• Off-road trims like the AT4 and AT4X boast Multimatic jounce control dampers and a new steering wheel.

Difference Between 2026 vs. 2027 Sierra 1500

The 2027 GMC Sierra 1500 takes huge steps up from the 2026 model, though both are still quite capable. As you'll see in an Elevation vs. SLT trim comparison, losing the SLT trim means you'll no longer have access to a mid-level luxury trim. In compensation, you'll have more premium appointments in earlier trims.

New 2027 TurboMax and V-8 engines boast increased output, complementing its more commanding appearance and taller maximum height of 79.6 inches vs. 78.65 inches for 2026. However, the 2027 iteration retains Regular, Double, and Crew Cab configurations.

Once you're behind the wheel, the differences become more apparent. The larger screens, newly available Multipro center console, available passenger display, and higher-grade materials make the 2027 Sierra truly impressive.

Summary

• Both models have similar, spacious cabins.
• The 2027 Sierra has a taller maximum height.
• For stronger engines, wait for the 2027 Sierra.
• An updated cabin awaits you with 2027 models.
