Compare the2023 GMC TerrainVS 2023 Infiniti QX55

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 QX55 doesn’t offer a back seat reminder.

When descending a steep, off-road slope, the Terrain’s standard Hill Descent Control allows you to creep down safely. The QX55 doesn’t offer Hill Descent Control.

Both the Terrain and the QX55 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the GMC Terrain is safer than the Infiniti QX55:

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

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Terrain the rating of “Top Safety Pick” for 2017, a rating granted to only 221 vehicles tested by the IIHS. The QX55 has not been tested, yet.

There are over 8 times as many GMC dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Terrain’s warranty.

J.D. Power and Associates rated the Terrain third among compact suvs in their 2022 Initial Quality Study. The QX55 isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks GMC above average in initial quality. With 42 more problems per 100 vehicles, Infiniti is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that GMC vehicles are more reliable than Infiniti With 36 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks GMC higher than Infiniti.

On the EPA test cycle the Terrain gets better mileage than the QX55:

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 QX55 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 QX55 requires premium, which can cost 20 to 55 cents more per gallon.

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 QX55 doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the GMC Terrain higher (7 out of 10) than the Infiniti QX55 (6). This means the Terrain produces up to 1.1 pounds less smog-producing pollutants than the QX55 every 15,000 miles.

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 QX55 doesn’t offer vehicle monitored tire inflation.

The Terrain has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the QX55; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 450 to 650 pounds less than the Infiniti QX55.

The Terrain is 4 inches shorter than the QX55, making the Terrain easier to handle, maneuver and park in tight spaces.

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 QX55 doesn’t offer active grille shutters.

The Terrain has 3 cubic feet more passenger volume than the QX55 (103.2 vs. 100.2).

The Terrain has .1 inches more front headroom, 1.3 inches more front legroom, 1.6 inches more rear headroom and 1 inch more rear legroom than the QX55.

The Terrain has a much larger cargo volume with its rear seat up than the QX55 with its rear seat up (29.6 vs. 26.9 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the QX55 with its rear seat folded (63.3 vs. 54.1 cubic feet).

The Terrain has a 1500 lbs. towing capacity. The QX55 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 QX55 doesn’t offer electronic trailer sway control.

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 QX55 does not have an oil pressure gauge.

The power windows standard on both the Terrain and the QX55 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 QX55 prevents the driver from operating the other windows just as it does the other passengers.

The Terrain’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 QX55 has an automatic rear view mirror, but its side mirrors don’t dim.

Both the Terrain and the QX55 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 QX55.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Terrain Denali has a standard wireless phone charging system (Qi) in the center console. The QX55 doesn’t offer wireless personal charging.

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 QX55 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 QX55 doesn’t offer an automated parking system.

The Terrain is available in both front-wheel drive and four-wheel drive configurations. The QX55 doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the Terrain owner. The Complete Car Cost Guide estimates that insurance for the Terrain will cost $2085 to $3675 less than the QX55 over a five-year period.

The Terrain will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Terrain will retain 48.41% to 52.67% of its original price after five years, while the QX55 only retains 44.12% to 44.72%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the GMC Terrain will be $7475 to $20204 less than for the Infiniti QX55.
