The Terrain SLT/AT4/Denali offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Trailblazer only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the Terrain and the Trailblazer have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, 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 all wheel drive, blind spot warning systems and rear cross-path warning.

Reliability

J.D. Power and Associates rated the Terrain second among compact suvs in their 2023 Initial Quality Study. The Trailblazer isn’t in the top three in its category.

Engine

The Terrain’s 1.5 turbo 4-cylinder produces 38 more horsepower (175 vs. 137) and 41 lbs.-ft. more torque (203 vs. 162) than the Trailblazer’s standard 1.2 turbo 3-cylinder. The Terrain’s 1.5 turbo 4-cylinder produces 20 more horsepower (175 vs. 155) and 29 lbs.-ft. more torque (203 vs. 174) than the Trailblazer’s optional 1.3 turbo 3-cylinder.

Fuel Economy and Range

The Terrain FWD’s standard fuel tank has 1.7 gallons more fuel capacity than the Trailblazer (14.9 vs. 13.2 gallons), for longer range between fill-ups. The Terrain AWD’s standard fuel tank has 2.4 gallons more fuel capacity than the Trailblazer (15.6 vs. 13.2 gallons).

The Terrain has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Trailblazer doesn’t offer a cap-less fueling system.

Suspension and Handling

For superior ride and handling, the GMC Terrain has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Trailblazer has a rear torsion beam axle, with a semi-independent rear suspension.

For a smoother ride and more stable handling, the Terrain’s wheelbase is 3.4 inches longer than on the Trailblazer (107.3 inches vs. 103.9 inches).

For better handling and stability, the track (width between the wheels) on the Terrain is 1.4 inches wider in the front and 1.2 inches wider in the rear than on the Trailblazer.

The Terrain Denali AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Trailblazer RS AWD (27.5 seconds @ .64 average G’s vs. 28.3 seconds @ .57 average G’s).

Passenger Space

The Terrain has 5 cubic feet more passenger volume than the Trailblazer (103.2 vs. 98.2).

The Terrain has 2.1 inches more front hip room, 1.8 inches more front shoulder room, .1 inches more rear headroom, .3 inches more rear legroom, 1.4 inches more rear hip room and 1.8 inches more rear shoulder room than the Trailblazer.

For enhanced passenger comfort on long trips the Terrain’s rear seats recline. The Trailblazer’s rear seats don’t recline.

Cargo Capacity

The Terrain has a much larger cargo volume with its rear seat up than the Trailblazer with its rear seat up (29.6 vs. 25.3 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the Trailblazer with its rear seat folded (63.3 vs. 54.4 cubic feet).

Pulling a handle automatically lowers the Terrain’s rear seats, to make changing between passengers and cargo easier. The Trailblazer doesn’t offer automatic folding seats.

Towing

The Terrain’s standard towing capacity is much higher than the Trailblazer’s (1500 vs. 1000 pounds).

Standard Trailer Sway Control on the Terrain uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Trailblazer doesn’t offer electronic trailer sway control.

Ergonomics

When two different drivers share the Terrain SLT/AT4/Denali, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Trailblazer doesn’t offer a memory system.

The Terrain SLT/AT4/Denali’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Trailblazer doesn’t offer an easy entry system.

The Terrain’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Trailblazer does not have an oil pressure gauge.

The Terrain (except SLE) offers an available heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Trailblazer doesn’t offer a heads-up display.

On a hot day the Terrain’s driver can lower all the windows from a distance using the keyless remote. The driver of the Trailblazer can only operate the windows from inside the vehicle, with the ignition on.

The Terrain’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Chevrolet only offers heated mirrors on the Trailblazer LT/ACTIV/RS.

When the Terrain SLT/AT4/Denali is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Trailblazer’s mirrors don’t automatically adjust for backing.

Both the Terrain and the Trailblazer offer available heated front seats. The Terrain Denali also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Trailblazer.

Optional air-conditioned seats in the Terrain Denali keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Trailblazer doesn’t offer air-conditioned seats.

The Terrain has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The Trailblazer LS doesn’t offer a rear seat center armrest.

The Terrain’s optional dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Trailblazer doesn’t offer dual zone air conditioning.

Both the Terrain and the Trailblazer offer rear vents. For greater rear passenger comfort, the Terrain has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Trailblazer doesn’t offer rear air conditioning vents, only heat vents.

The Terrain’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Trailblazer’s available navigation system doesn’t offer real-time traffic updates.

The Terrain Denali’s optional Automatic Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Trailblazer doesn’t offer an automated parking system.

Recommendations

The GMC Terrain outsold the Chevrolet Trailblazer by 42% during 2022.
