For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-70 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Terrain doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mazda CX-70 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 Mazda CX-70 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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.

The CX-70 Premium has a standard Secondary Collision Reduction System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Terrain doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The CX-70 Premium Plus/Turbo S has standard Rear Smart City Brake Support that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Terrain doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-70. But it costs extra on the Terrain.

The CX-70 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Terrain’s blind spot costs extra.

To help make backing out of a parking space safer, the CX-70 has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. GMC charges extra for Rear Cross Traffic Alert on the Terrain and the Terrain’s Rear Cross Traffic Alert does not include automatic braking.

The CX-70’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.

Both the CX-70 and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

The Mazda CX-70 weighs 1168 to 1779 pounds more than the GMC Terrain. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda CX-70 is much safer than the Terrain:

The Mazda CX-70 achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Terrain is not a “Top Safety Pick” for 2024.

Warranty

The CX-70’s corrosion warranty is unlimited miles longer than the Terrain’s (unlimited vs. 100,000 miles).

Reliability

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mazda vehicles are more reliable than GMC vehicles. J.D. Power ranks Mazda above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, GMC is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Mazda vehicles are more reliable than GMC vehicles. Consumer Reports ranks Mazda 17 places higher in reliability than GMC.

Engine

The CX-70’s standard 3.3 turbo 6-cylinder hybrid produces 105 more horsepower (280 vs. 175) and 129 lbs.-ft. more torque (332 vs. 203) than the Terrain’s 1.5 turbo 4-cylinder. The CX-70 PHEV’s standard 2.5 DOHC 4-cylinder hybrid produces 148 more horsepower (323 vs. 175) and 166 lbs.-ft. more torque (369 vs. 203) than the Terrain’s 1.5 turbo 4-cylinder. The CX-70 Turbo S’ standard 3.3 turbo 6-cylinder hybrid produces 165 more horsepower (340 vs. 175) and 166 lbs.-ft. more torque (369 vs. 203) than the Terrain’s 1.5 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the CX-70 with its standard engine running its gasoline engine gets better fuel mileage than the Terrain AWD (24 city/28 hwy vs. 23 city/28 hwy).

The CX-70 PHEV can travel with zero emissions for 26 miles. The Terrain can’t move without running its internal combustion engine.

Regenerative brakes improve the CX-70’s fuel efficiency by converting inertia back into energy instead of wasting it. The Terrain doesn’t offer a regenerative braking system.

The CX-70’s standard fuel tank has 3.6 gallons more fuel capacity than the Terrain FWD’s standard fuel tank (18.5 vs. 14.9 gallons), for longer range between fill-ups. The CX-70 Turbo S’ standard fuel tank has 4 gallons more fuel capacity than the Terrain AWD’s standard fuel tank (19.6 vs. 15.6 gallons).

The CX-70 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Terrain. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

For better stopping power the CX-70’s brake rotors are larger than those on the Terrain:

	CX-70	CX-70 Turbo S/PHEV	Terrain
Front Rotors	12.9 inches	13.7 inches	11.8 inches
Rear Rotors	13.8 inches	13.8 inches	11.3 inches

The CX-70’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Terrain are solid, not vented.

Tires and Wheels

For better traction, the CX-70 has larger standard tires than the Terrain (265/55R19 vs. 225/65R17). The CX-70 Premium’s tires are larger than the largest tires available on the Terrain (275/45R21 vs. 235/50R19).

The CX-70’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain SLE/AT4’s standard 65 series tires. The CX-70 Premium’s tires have a lower 45 series profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the CX-70 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Terrain SLE/AT4. The CX-70 Premium’s 21-inch wheels are larger than the 19-inch wheels optional on the Terrain.

Suspension and Handling

For a smoother ride and more stable handling, the CX-70’s wheelbase is 15.5 inches longer than on the Terrain (122.8 inches vs. 107.3 inches).

For better handling and stability, the track (width between the wheels) on the CX-70 is 4.8 inches wider in the front and 4.7 inches wider in the rear than on the Terrain.

The CX-70 PHEV Premium Plus handles at .80 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The CX-70 PHEV Premium Plus executes Motor Trend’s “Figure Eight” maneuver quicker than the Terrain Denali AWD (26.9 seconds @ .66 average G’s vs. 27.5 seconds @ .64 average G’s).

For greater off-road capability the CX-70 has a 1.1 inches greater minimum ground clearance than the Terrain SLE (8 vs. 6.9 inches), allowing the CX-70 to travel over rougher terrain without being stopped or damaged. The CX-70 Turbo S/PHEV’s minimum ground clearance is .2 inch higher than on the Terrain SLT/AT4/Denali (8.1 vs. 7.9 inches).

Passenger Space

The CX-70 has 38.4 cubic feet more passenger volume than the Terrain (141.6 vs. 103.2).

The CX-70 has .8 inches more front legroom, 1.8 inches more front hip room, 2 inches more front shoulder room, .8 inches more rear headroom, 3.7 inches more rear hip room and 2.5 inches more rear shoulder room than the Terrain.

Cargo Capacity

The CX-70 has a much larger cargo volume with its rear seat up than the Terrain with its rear seat up (39.6 vs. 29.6 cubic feet). The CX-70 has a much larger cargo volume with its rear seat folded than the Terrain with its rear seat folded (75.3 vs. 63.3 cubic feet).

Towing

The CX-70’s standard towing capacity is much higher than the Terrain’s (3500 vs. 1500 pounds). Maximum trailer towing in the GMC Terrain is only 1500 pounds. The CX-70 offers up to a 5000 lbs. towing capacity.

Servicing Ease

The CX-70 uses gas struts to support the hood for easier service access. The Terrain uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the CX-70 is mounted longitudinally (North-South), instead of sideways, as in the Terrain. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The CX-70’s front and rear power windows all open or close 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 Terrain’s passenger windows don’t close automatically.

The CX-70’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Terrain’s manually variable intermittent wipers have to be constantly adjusted.

To help drivers see further while navigating curves, the CX-70 Turbo S has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Terrain doesn’t offer cornering lights.

Manual rear side window sunshades are available in the CX-70 to help block heat and glare for the rear passengers. The Terrain doesn’t offer rear side window sunshades.

The CX-70 Premium’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Terrain has an automatic rear view mirror, but its side mirrors don’t dim.

Both the Mazda CX-70 and GMC Terrain offer exterior mirrors that can be folded to provide convenience. The CX-70 offers available power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Terrain’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The CX-70 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mazda CX-70 has a standard wireless phone charging system (Qi) in the center console. Only the Terrain Denali offers wireless charging.
