What’s New for 2026 GMC Terrain?

July 2nd, 2025 by

2026 GMC Terrain

The GMC Terrain is a compact SUV that takes design cues from GMC’s larger, rugged pickup trucks, such as the Sierra. While it shares its underlying platform and engine with the Chevrolet Equinox, the Terrain distinguishes itself with a more upscale interior and technology features borrowed from the larger GMC Acadia, such as a 15-inch diagonal Premium GMC Infotainment System with Google built-in, an 11-inch diagonal Driver Information Center, available wireless charging, and advanced driver-assistance systems like Adaptive Cruise Control and HD Surround Vision.

For those seeking off-road capability, your GMC Dealership Near Me has a new AT4 trim, which includes features like a front skid plate with a steel underbody shield, an off-road-tuned suspension, durable all-terrain tires, and an AT4-exclusive Terrain mode for low-speed crawls. Meanwhile, the luxurious Denali model caters to buyers looking for premium appointments, offering perforated leather-appointed seating, ventilated front seats, a memory package, and a head-up display.

What’s New for 2026 GMC Terrain?

For the 2026 model year, the GMC Terrain lineup expands with the introduction of two new models: the AT4 and the Denali.

The Terrain AT4 is designed for off-road enthusiasts, offering:

  • Increased ride height
  • Robust all-terrain tires
  • Underbody protection
  • Red front recovery hooks

The Terrain Denali, positioned as the top-tier trim, focuses on luxury and comfort, providing:

  • A more premium interior
  • Standard heated rear seats
  • Unique 19-inch wheels
  • A specially tuned suspension for enhanced ride comfort

Engine and Performance

Every GMC Terrain comes with a turbocharged 1.5-liter four-cylinder engine that produces 175 horsepower. If you opt for a front-wheel-drive model, it’ll be paired with a continuously variable automatic transmission (CVT). However, all-wheel-drive Terrains get a more traditional eight-speed automatic transmission. These powertrain setups are the same as those found in the mechanically similar Chevy Equinox.

While the Terrain offers a comfortable ride and stable handling across all trims, its acceleration tends to be unimpressed. There’s not much in the way of excitement for the driver.

Ride and Handling by Trim

When it comes to ride comfort, the Terrain AT4 offers the plushest experience among the three trims. That’s largely due to the thicker sidewalls of its all-terrain tires, which help absorb road imperfections.

The top-of-the-line Denali trim, on the other hand, can come with larger 20-inch wheels and lower-profile all-season tires. To prevent these bigger wheels from making the ride harsh, GMC engineers equipped the Denali with a more advanced suspension system. This sophisticated setup ensures a smooth and comfortable journey, even with the larger wheel option.

Towing and Payload Capacity

The GMC Terrain’s towing capacity varies depending on its drivetrain. All-wheel-drive (AWD) models can tow up to 1,500 pounds, while front-wheel-drive (FWD) models have a lower maximum towing capacity of 800 pounds. This means AWD models offer significantly greater capability for pulling trailers or other loads.

Fuel Economy and Real-World MPG

The official fuel economy estimates for the 2026 GMC Terrain are not yet available from the EPA. However, we can look at the 2025 model for an indication of expected fuel efficiency.

The 2025 front-wheel-drive (FWD) Terrain Elevation was rated by the EPA at 26 mpg in the city and 28 mpg on the highway. Opting for the all-wheel-drive (AWD) model in 2025 resulted in a slightly lower city rating of 24 mpg, while the highway rating remained at 28 mpg.

In independent real-world testing, an all-wheel-drive Terrain Elevation achieved 30 mpg on the highway, surpassing its EPA estimate.

Interior, Comfort, and Cargo

The GMC Terrain is a two-row SUV that accommodates up to five passengers. Its interior design marries the rugged aesthetic found in other GMC trucks with a wealth of modern conveniences and technology. A prominent feature is the large, vertically oriented 15.0-inch infotainment touchscreen dominating the dashboard.

Even the base models come well-equipped with standard features such as heated seats, a heated steering wheel, and remote start. The interior materials are of good quality, and the seats are notably comfortable with ample cushioning.

With the addition of the off-road-focused AT4 and the luxurious Denali models, each trim will offer a distinct interior style that aligns with its specific character. While the cargo area behind the rear seats appears spacious, a more definitive assessment will be provided once a real-world cargo test is conducted using carry-on suitcases.
