Overview
The 2026 GMC Terrain is a compact two-row crossover — smaller than the Acadia and positioned as an alternative to the Chevrolet Equinox with a premium GMC interior.
Same 1.5L turbo engine and similar size. Terrain interior is noticeably more premium. Equinox is cheaper. For buyers who notice interior quality, the Terrain justifies the premium.

Efficiency & Powertrain
EPA highway rating measured at 55 mph. Real-world highway at 70 mph is typically 29–31 mpg. Towing near max capacity reduces highway fuel economy 23–33% — budget accordingly for trailer trips.
At 31 mpg highway, the Terrain competes directly with the Honda CR-V and Toyota RAV4 for fuel efficiency. For buyers prioritizing economy over performance, it's a strong choice.
The single 1.5L turbocharged four-cylinder produces 175 hp and 203 lb-ft — adequate for daily driving and returning up to 31 mpg highway. Not sporty, but well-suited for commuting and errands.
Interior & Cargo
The Terrain's interior materials are a step above the comparable Equinox — softer touch points, more stitching, and quieter cabin. It's the same mechanical package with a meaningfully better feel.
Cargo behind the rear seat reaches 29.6 cubic feet — slightly above average for the compact class. Max cargo (seats folded) is 63.3 cubic feet. Interior quality at the SLT and above is notably higher than the Chevrolet Equinox — GMC's premium positioning is genuine.
AT4 & Denali

Denali Terrain at $44,995 with Bose audio, leather, and AWD is exceptionally well-appointed for the price. It delivers near-luxury compact SUV quality without luxury brand pricing.
The AT4 adds raised ground clearance, all-terrain tires, and AWD as standard — making the Terrain a mild off-road capable compact SUV. The Denali brings Bose audio, premium leather, and heated steering wheel at $44,995.
Reliability
Terrain reliability is good — the 1.5L turbo engine is shared with the Equinox and has a solid track record. AWD system is proven. Overall one of the more reliable compact SUVs in the GM lineup.
