When descending a steep, off-road slope, the Terrain’s standard Hill Descent Control allows you to creep down safely. The CX-30 doesn’t offer Hill Descent Control.

Both the Terrain and the CX-30 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, around view monitors and rear cross-path warning.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Warranty

The Terrain’s corrosion warranty is 1 year longer than the CX-30’s (6 vs. 5 years).

There are over 3 times as many GMC dealers as there are Mazda dealers, which makes it much easier should you ever need service under the Terrain’s warranty.

Reliability

J.D. Power and Associates rated the Terrain second among compact suvs in their 2023 Initial Quality Study. The CX-30 isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks GMC above average in initial quality. With 36 more problems per 100 vehicles, Mazda is rated below average.

Engine

The Terrain’s 1.5 turbo 4-cylinder produces 17 lbs.-ft. more torque (203 vs. 186) than the CX-30’s standard 2.5 DOHC 4-cylinder.

Fuel Economy and Range

In heavy traffic or at stoplights the Terrain’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CX-30 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the GMC Terrain uses regular unleaded gasoline. The CX-30 with the 2.5 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

The Terrain FWD’s standard fuel tank has 2.2 gallons more fuel capacity than the CX-30 (14.9 vs. 12.7 gallons), for longer range between fill-ups. The Terrain AWD’s standard fuel tank has 2.9 gallons more fuel capacity than the CX-30 (15.6 vs. 12.7 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 CX-30 doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the GMC Terrain higher (7 out of 10) than the Mazda CX-30 (5 to 7). This means the Terrain produces up to 8 pounds less smog-producing pollutants than the CX-30 every 15,000 miles.

Transmission

A nine-speed automatic is standard on the GMC Terrain, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the CX-30.

Brakes and Stopping

For better stopping power the Terrain’s brake rotors are larger than those on the CX-30:

	Terrain	CX-30
Front Rotors	11.8 inches	11.6 inches
Rear Rotors	11.3 inches	10.4 inches

Tires and Wheels

For better traction, the Terrain has larger standard tires than the CX-30 (225/65R17 vs. 215/65R16). The Terrain’s optional tires are larger than the largest tires available on the CX-30 (235/50R19 vs. 215/65R16).

The Terrain’s optional tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the CX-30 Select/Preferred/Carbon/Premium’s 55 series tires.

For better ride, handling and brake cooling the Terrain SLE/AT4 has standard 17-inch wheels. Smaller 16-inch wheels are standard on the CX-30 2.5 S. The Terrain’s optional 19-inch wheels are larger than the 18-inch wheels on the CX-30 Select/Preferred/Carbon/Premium.

The Terrain 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 CX-30 doesn’t offer vehicle monitored tire inflation.

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 Mazda CX-30 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 2.9 inches longer than on the CX-30 (107.3 inches vs. 104.4 inches).

The Terrain Denali AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the CX-30 2.5 S Premium (27.5 seconds @ .64 average G’s vs. 27.9 seconds @ .6 average G’s).

Chassis

The front grille of the Terrain offers available electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The CX-30 doesn’t offer active grille shutters.

The Terrain uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The CX-30 doesn’t offer active noise cancellation.

Passenger Space

The Terrain has 9.1 cubic feet more passenger volume than the CX-30 (103.2 vs. 94.1).

The Terrain has 1.9 inches more front headroom, 1.6 inches more front shoulder room, .2 inches more rear headroom, 3.4 inches more rear legroom and 2 inches more rear shoulder room than the CX-30.

For enhanced passenger comfort on long trips the Terrain’s rear seats recline. The CX-30’s rear seats don’t recline.

Cargo Capacity

The Terrain has a much larger cargo volume with its rear seat up than the CX-30 with its rear seat up (29.6 vs. 20.2 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the CX-30 with its rear seat folded (63.3 vs. 45.2 cubic feet).

Pulling a handle automatically lowers the Terrain’s rear seats, to make changing between passengers and cargo easier. The CX-30 doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the Terrain SLT/AT4/Denali’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-30 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The Terrain has a 1500 lbs. towing capacity. The CX-30 has no towing capacity.

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 CX-30 doesn’t offer electronic trailer sway control.

Ergonomics

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 CX-30 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 CX-30 does not have an oil pressure gauge.

The power windows standard on both the Terrain and the CX-30 have locks to prevent small children from operating them. When the lock on the Terrain is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-30 prevents the driver from operating the other windows just as it does the other passengers.

On a hot day the Terrain’s driver can lower all the windows from a distance using the keyless remote. The driver of the CX-30 can only operate the windows from inside the vehicle, with the ignition on.

The Terrain’s standard Keyless Access allow you to unlock the doors from any outside door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. Pushbutton Start standard on the CX-30 only offers hands-free access for the ignition, none to unlock the vehicle. Pushbutton Start is not available on the CX-30 Select/Preferred/Carbon/Premium.

To improve rear visibility by keeping the rear window clear, the Terrain has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the CX-30 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Terrain’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-30 Select/Preferred/Carbon/Premium.

Both the Terrain and the CX-30 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 CX-30.

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 CX-30 doesn’t offer air-conditioned seats.

The Terrain 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 CX-30 doesn’t offer a house-current electrical outlet.

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 CX-30 doesn’t offer an automated parking system.

Model Availability

The Terrain is available in both front-wheel drive and four-wheel drive configurations. The CX-30 doesn’t offer a two-wheel drive configuration.
