2027 GMC Sierra 1500 Colors & Style
A new generation needs a signature style, and the GMC Sierra 1500 is no different. A vertically inclined grille and updated exterior shape make the truck feel taller and more dominant on the road – further emboldened by larger tires across the lineup.
There are also three brand-new exterior colors, joining six fan-favorite shades:
- Mesa Red
- Azurite Blue Metallic
- 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 new MultiPro center console and 16.3-inch diagonal touchscreen.

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 more seat articulation, wireless charging, and a hidden storage compartment. Our recent 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.
- AT4X: Unlock any trail with Multimatic jounce control dampers, Baja Drive Mode, and underbody cameras.
- Denali: A 15-inch diagonal multicolor Head-Up Display lets you keep your eyes on the road, while the panoramic sunroof lets you have natural lighting on your own terms.
- Denali Ultimate: A 16-speaker Bose® sound system projects music through segment-exclusive headrest speakers. Ventilated seating, an 11.5-inch passenger screen, and 22-inch diamond-cut wheels finish the high-end image.
- 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 a new steering wheel and Multimatic jounce control dampers.
- Luxury looks fantastic with the Denali and the Denali Ultimate, with new features and stronger materials.

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, unlike in 2026. In compensation, the new 2027 V-8 engines boast slightly more power.
The 2027 Sierra 1500 looks larger than the previous year. That's thanks to new wheel sizes and the redesigned exterior, giving the 2027 model up to 79.6 inches in height vs. 78.4 inches for 2026. However, each cabin still offers over 44 inches of legroom and 43 inches of headroom, and the 2027 model comes in similar Regular, Double, and Crew cabs as in 2026.
Once you're behind the wheel, the differences become more apparent. The larger screens, newly available Multipro workspace, optional passenger display, and higher-grade materials make the 2027 Sierra look more impressive across the board.
- Both models have similar, spacious cabins.
- The 2027 Sierra is taller.
- For stronger engines, wait for the 2027 Sierra.
- An updated cabin awaits behind the wheel of the 2027 model.
