2027 GMC SUV Lineup Gets Smarter and More Colorful

Estimated reading time: 5 minutes · Last updated: 26 August 2026

The 2027 GMC SUV lineup brings modest mechanical changes, new paint options and a charging improvement that matters for EV owners. Key mechanical work centers on the Terrain, where the CVT is removed so that 1,500 pounds towing replaces the previous 800 pounds limit on FWD models. The Hummer EV adds a NACS port, widening public charging access. New paints and feature swaps hit Acadia and Yukon, while a commemorative Hummer EV Icon 25 Edition appears. These model-year details were compiled as first reported by MotorTrend and summarize what buyers should expect from GMC’s SUV range for 2027.

Terrain: drivetrain change boosts towing and adds an interior camera

GMC reworked the Terrain’s powertrain strategy for 2027 by dropping the continuously variable transmission and equipping every Terrain with an eight-speed automatic. That shift means front-wheel-drive Terrains can tow 1,500 pounds now, compared with the previous 800 pounds when fitted with the CVT. The change is mechanical rather than cosmetic, aimed at giving the smallest GMC SUV clearer utility without altering its packaging.

Inside, the 2027 Terrain gains an interior monitoring camera and GMC lists an optional three-year subscription to OnStar One connectivity on all models. The moving parts here are straightforward: the eight-speed replaces the CVT, towing capability increases from 800 pounds to 1,500 pounds, and the cabin gets new monitoring hardware and connectivity options.

For buyers who used to rule out the Terrain because of its towing limits, the switch to a single eight-speed gearbox across the range is the most consequential update in this model year.

Acadia and Yukon: new colors, cameras and more tech on higher trims

GMC revised paint and equipment choices for the 2027 Acadia and Yukon. The Acadia picks up Trailstone Green on Elevation trims and adds Ink metallic dark blue to Denali and Denali Ultimate, while Crystal purple and Downpour teal blue are removed. GMC also makes an interior camera standard across every Acadia for 2027 and introduces an AT4 Reserve outfitted with durable rubber floor protection plus a Bose audio system with 16 speakers.

Denali buyers get Super Cruise hands-free driving as standard on Acadia, and new wheel options include 18-inch black-painted wheels or 20-inch machined-face wheels. On the Yukon, Coastal Dune joins AT4 exterior color choices while Midnight Pine is removed; fresh 20- and 22-inch black-accented wheel designs are available.

GMC also offers an Elevation Preferred package for the Yukon that bundles a power sunroof, Super Cruise hands-free driving, a digital rearview mirror and a head-up display, shifting some tech previously confined to higher trims into a single option package.

Hummer EV: charging standardization and a 25th‑anniversary Icon edition

The headline change for GMC’s largest SUV is functional: the 2027 Hummer EV adopts a NACS port, which improves interoperability with many public charging networks that use that standard. For owners, the practical implication is broader public charger access for the electric Hummer compared with older proprietary ports.

GMC marks 25 years since the Hummer H2 with the Icon 25 Edition, finished in Icon Yellow and riding on 22-inch black wheels. The cabin is trimmed entirely in black and includes a serialized dedication plaque, and the infotainment features bespoke graphics that reference Hummer heritage models. The special edition can be ordered with either the 2X dual-motor or the 3X tri-motor powertrain.

Those updates blend a functional change—NACS charging—with a product celebration aimed at buyers who want a visibly distinct Hummer EV. The NACS port is the most meaningful technical improvement for everyday EV use.

How the updates could play out

The bottom line

GMC’s 2027 updates are incremental but targeted: a mechanical swap on the Terrain that meaningfully raises towing, broader charging access for the Hummer EV via NACS, and a handful of color and equipment reshuffles across Acadia and Yukon. Buyers who value towing capacity or charging interoperability will find the most substance in this model year, while those seeking deep mechanical changes should look for future revisions. Exact pricing, ordering windows and production volumes remain to be published, and those details will determine how the changes translate into buyer choices at dealerships.
