For enhanced safety, the GMC Terrain’s rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Mazda CX-3 doesn’t offer comfort guides on its rear seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Terrain are reminded to check the back seat if they opened the rear door before starting out. The CX-3 doesn’t offer a back seat reminder.

The Terrain Denali offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The CX-3 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.

Compared to metal, the Terrain’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-3 has a metal gas tank.

Both the Terrain and the CX-3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems and rear cross-path warning.

The GMC Terrain weighs 497 to 992 pounds more than the Mazda CX-3. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the GMC Terrain is safer than the Mazda CX-3:

The Terrain’s corrosion warranty is 1 year longer than the CX-3’s (6 vs. 5 years).

There are almost 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.

The Terrain’s standard 1.5 turbo 4-cyl. produces 22 more horsepower (170 vs. 148) and 57 lbs.-ft. more torque (203 vs. 146) than the CX-3’s 2.0 DOHC 4-cyl. The Terrain’s optional 2.0 turbo 4-cyl. produces 104 more horsepower (252 vs. 148) and 114 lbs.-ft. more torque (260 vs. 146) than the CX-3’s 2.0 DOHC 4-cyl.

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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CX-3 doesn’t offer an automatic engine start/stop system.

The Terrain FWD’s standard fuel tank has 3 gallons more fuel capacity than the CX-3 AWD’s standard fuel tank (14.9 vs. 11.9 gallons), for longer range between fill-ups. The Terrain AWD’s standard fuel tank has 2.9 gallons more fuel capacity than the CX-3 FWD’s standard fuel tank (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-3 doesn’t offer a cap-less fueling system.

For better traction, the Terrain has larger standard tires than the CX-3 (225/65R17 vs. 215/60R16). The Terrain’s optional tires are larger than the largest tires available on the CX-3 (235/50R19 vs. 215/60R16).

For better ride, handling and brake cooling the Terrain has standard 17-inch wheels. Smaller 16-inch wheels are standard on the CX-3 Sport. The Terrain’s optional 19-inch wheels are larger than the 18-inch wheels on the CX-3 Grand Touring/Touring.

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-3 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-3 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 6.1 inches longer than on the CX-3 (107.3 inches vs. 101.2 inches).

For better handling and stability, the track (width between the wheels) on the Terrain is 2.3 inches wider in the front and 2.6 inches wider in the rear than on the CX-3.

For greater off-road capability the Terrain SLE has a greater minimum ground clearance than the CX-3 (6.9 vs. 6.1 inches), allowing the Terrain to travel over rougher terrain without being stopped or damaged. The Terrain SLT/Denali’s minimum ground clearance is 1.7 inches higher than on the CX-3 Touring/Grand Touring (7.9 vs. 6.2 inches).

The front grille of the Terrain uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The CX-3 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-3 doesn’t offer active noise cancellation.

The Terrain has a much larger cargo volume with its rear seat up than the CX-3 with its rear seat up (29.6 vs. 12.4 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the CX-3 with its rear seat folded (63.3 vs. 44.5 cubic feet).

Pressing a switch automatically lowers the Terrain SLE/SLT/Denali’s rear seats, to make changing between passengers and cargo easier. The CX-3 doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier, especially for short adults, the Terrain (except SL) offers an optional power liftgate, which opens and closes automatically by pressing a button, or on the Terrain SLT/Denali, by just kicking your foot under the back bumper, completely leaving your hands free.

The Terrain (except SL/SLE)’s optional 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-3 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-3 has neither an oil pressure gauge nor a temperature gauge.

The power windows standard on both the Terrain and the CX-3 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-3 prevents the driver from operating the other windows just as it does the other passengers.

The Terrain’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The CX-3’s passenger windows don’t open automatically.

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-3 can only operate the windows from inside the vehicle, with the ignition on.

The Terrain has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The CX-3 only offers an automatic headlight on/off feature as an extra cost option.

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-3 Touring/Grand Touring.

When the Terrain with available tilt-down mirrors 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 CX-3’s mirrors don’t automatically adjust for backing.

The Terrain SLT/Denali has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The CX-3 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Terrain and the CX-3 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-3.

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-3 doesn’t offer air-conditioned seats.

The Terrain (except SL)’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 CX-3 doesn’t offer dual zone air conditioning.

Both the Terrain and the CX-3 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 CX-3 doesn’t offer rear air conditioning vents, only heat vents.

The Terrain (except SL) 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-3 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-3 doesn’t offer an automated parking system.
