Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than GMC vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 17 more problems per 100 vehicles, GMC is ranked 20th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than GMC vehicles. J.D. Power ranks Chevrolet 6th in reliability, above the industry average. With 32 more problems per 100 vehicles, GMC is ranked 18th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Chevrolet vehicles are more reliable than GMC vehicles. Consumer Reports ranks Chevrolet 2 places higher in reliability than GMC.

Engine

The Blazer’s standard 2.5 DOHC 4 cyl. produces 23 more horsepower (193 vs. 170) than the Terrain’s standard 1.5 turbo 4 cyl. The Blazer’s optional 3.6 DOHC V6 produces 53 more horsepower (305 vs. 252) and 9 lbs.-ft. more torque (269 vs. 260) than the Terrain’s optional 2.0 turbo 4 cyl.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Blazer V6’s fuel efficiency. The Terrain doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Chevrolet Blazer uses regular unleaded gasoline. The Terrain with the 2.0 turbo 4 cyl. engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Blazer FWD’s standard fuel tank has 4.5 gallons more fuel capacity than the Terrain’s standard fuel tank (19.4 vs. 14.9 gallons), for longer range between fill-ups. The Blazer AWD’s standard fuel tank has 6.1 gallons more fuel capacity than the Terrain’s standard fuel tank (21.7 vs. 15.6 gallons).

Brakes and Stopping

For better stopping power the Blazer’s brake rotors are larger than those on the Terrain:

Terrain 2.0T

Front Rotors

12.64 inches

11.8 inches

12.6 inches

Rear Rotors

Tires and Wheels

For better traction, the Blazer has larger standard tires than the Terrain (235/65R18 vs. 225/65R17). The Blazer RS/Premier’s optional tires are larger than the largest tires available on the Terrain (265/45R21 vs. 235/50R19).

The Blazer RS/Premier’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the Blazer has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Terrain. The Blazer RS/Premier’s optional 21-inch wheels are larger than the 19-inch wheels optional on the Terrain.

The Chevrolet Blazer’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The GMC Terrain only has 5 wheel lugs per wheel.

Suspension and Handling

The Blazer has standard front and rear stabilizer bars, which help keep the Blazer flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Blazer’s wheelbase is 5.4 inches longer than on the Terrain (112.7 inches vs. 107.3 inches).

For better handling and stability, the track (width between the wheels) on the Blazer is 4.1 inches wider in the front and 3.7 inches wider in the rear than on the Terrain.

Passenger Space

The Blazer has 4.6 cubic feet more passenger volume than the Terrain (107.8 vs. 103.2).

The Blazer has .1 inches more front legroom, 1.2 inches more front hip room, 1.9 inches more front shoulder room, .1 inches more rear headroom, 2.4 inches more rear hip room and 3 inches more rear shoulder room than the Terrain.

Cargo Capacity

The Blazer has a larger cargo volume with its rear seat up than the Terrain with its rear seat up (30.5 vs. 29.6 cubic feet). The Blazer has a larger cargo volume with its rear seat folded than the Terrain with its rear seat folded (64.2 vs. 63.3 cubic feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Blazer. The Terrain doesn’t offer locking storage for small valuables.

Towing

Maximum trailer towing in the GMC Terrain is limited to 3500 pounds. The Blazer offers up to a 4500 lbs. towing capacity.

Ergonomics

The Blazer has a standard 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. Dual zone air conditioning costs extra on the Terrain and isn’t available on the Terrain SL.

The Blazer’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Terrain SL doesn’t offer automatic air conditioning.

The Blazer (except L)’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 Terrain’s available navigation system doesn’t offer real-time traffic updates.
