Compare the2026 Chevrolet TrailblazerVS 2025 GMC Terrain

For enhanced safety, the front seat shoulder belts of the Chevrolet Trailblazer are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Terrain doesn’t offer height-adjustable seat belts.

The Chevrolet Trailblazer has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Terrain doesn’t offer knee airbags.

Both the Trailblazer and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

There are over 73 percent more Chevrolet dealers than there are GMC dealers, which makes it much easier should you ever need service under the Trailblazer’s warranty.

For better traction, the Trailblazer RS’ tires are larger than the largest tires available on the Terrain (245/45R19 vs. 235/65R17).

The Trailblazer LS/LT/ACTIV’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain’s standard 65 series tires. The Trailblazer RS’ tires have a lower 45 series profile than the Terrain’s optional 55 series tires.

The Trailblazer has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Terrain doesn’t offer vehicle monitored tire inflation.

For greater off-road capability the Trailblazer has a 2.2 inches greater minimum ground clearance than the Terrain (8 vs. 5.8 inches), allowing the Trailblazer to travel over rougher terrain without being stopped or damaged.

The Chevrolet Trailblazer may be more efficient, handle and accelerate better because it weighs about 350 to 400 pounds less than the GMC Terrain.

The Trailblazer AWD can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Trailblazer can be unhitched and driven around locally. The Terrain can’t be towed flat on the ground.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Trailblazer’s available exterior PIN entry system. The Terrain doesn’t offer an exterior PIN entry system, and its OnStar® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The Trailblazer LT/ACTIV/RS offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Terrain doesn’t offer a house-current electrical outlet.
