For drivers in Sidney, Westerville, and Columbus, the choice often comes down to two heavy hitters: the 2026 GMC Terrain and the 2026 Chevy Equinox. Both SUVs are built on the same robust GM D2 platform, sharing engines and chassis engineering. However, to call them “identical” would be a mistake.
The difference lies in the philosophy. The Equinox is designed as a value-forward, everyday family hauler. The 2026 GMC Terrain positions itself as the “Professional Grade” alternative, offering superior standard technology, rugged truck-inspired styling, and genuine off-road capability in the AT4 trim.
At Chesrown Chevrolet GMC, we carry both. This unbiased technical comparison breaks down the horsepower, interior dimensions, and towing specs to help you decide which SUV belongs in your driveway.
Both vehicles utilize the updated 1.5L Turbocharged 4-Cylinder (LSD) engine. This powertrain balances efficiency with torque-rich acceleration, ideal for merging onto I-75.
The critical distinction is in the transmission pairing. For 2026, both models utilize a Continuously Variable Transmission (CVT) for Front-Wheel Drive (FWD) configurations to maximize fuel economy. However, if you opt for All-Wheel Drive (AWD), which we highly recommend for Ohio winters, you receive a calibrated 8-Speed Automatic Transmission. This traditional automatic provides sharper shift points and a more connected driving feel, particularly when towing.
| Feature | 2026 GMC Terrain (AWD) | 2026 Chevy Equinox (AWD) | Advantage |
|---|---|---|---|
| Engine | 1.5L Turbo 4-Cyl | 1.5L Turbo 4-Cyl | Draw |
| Horsepower | 175 hp @ 5,600 rpm | 175 hp @ 5,600 rpm | Draw |
| Torque | 203 lb-ft | 203 lb-ft | Draw |
| Transmission | 8-Speed Automatic | 8-Speed Automatic | Draw |
| Max Towing | 1,500 lbs | 1,500 lbs | Draw |
| Fuel Economy (Est.) | 24 City / 28 Hwy | 24 City / 29 Hwy | Equinox (+1 Hwy) |
Engineering Insight: While the numbers are identical, the GMC Terrain AT4 trim includes a dedicated “Off-Road” drive mode and steel skid plates that the Equinox ACTIV lacks, making the Terrain the superior choice for unpaved roads in rural Shelby County.

| This is where the 2026 GMC Terrain creates a massive gap. Chevrolet equips the Equinox with a respectable 11.3-inch diagonal infotainment screen. It is crisp, responsive, and Google-integrated. | However, GMC has standardized a massive 15-inch Premium Infotainment System across the entire Terrain lineup. This portrait-oriented screen dominates the center stack, allowing for split-screen multitasking (e.g., viewing Navigation and Audio simultaneously without cramping the interface). |
Since they share a chassis, interior volume is effectively a tie. Both offer 29.8 cubic feet of cargo space behind the second row, expanding to 63.5 cubic feet with the seats folded flat. This is sufficient space to load a week’s worth of groceries from the Sidney Kroger or sports gear for a tournament in Dublin.
GM has introduced “rugged” trims for both models, but they serve different purposes.
