Safety

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX30 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 the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Infiniti QX30 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 front seat belts.

Both the QX30 and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

Warranty

The QX30 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Terrain’s 3-year/36,000-mile basic warranty expires 1 year and 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX30 1 year and 10,000 miles longer than GMC covers the Terrain. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Terrain ends after only 5 years or 60,000 miles.

The QX30’s corrosion warranty is 1 year and unlimited miles longer than the Terrain’s (7/unlimited vs. 6/100,000).

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than GMC vehicles. J.D. Power ranks Infiniti 14th in initial quality, above the industry average. With 7 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 Infiniti vehicles are more reliable than GMC vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 36 more problems per 100 vehicles, GMC is ranked 18th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than GMC vehicles. Consumer Reports ranks Infiniti 19 places higher in reliability than GMC.

Engine

The QX30’s 2.0 turbo 4 cyl. produces 38 more horsepower (208 vs. 170) and 55 lbs.-ft. more torque (258 vs. 203) than the Terrain’s standard 1.5 turbo 4 cyl.

Transmission

The QX30 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Terrain doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the QX30’s brake rotors are larger than those on the Terrain:

Tires and Wheels

For better traction, the QX30 has larger tires than the Terrain (235/50R18 vs. 225/65R17).

The QX30’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain’s standard 65 series tires. The QX30’s optional tires have a lower 45 series profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the QX30 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Terrain.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX30 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Terrain doesn’t offer run-flat tires.

Suspension and Handling

The QX30 has standard front and rear stabilizer bars, which help keep the QX30 flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

The QX30 Sport handles at .88 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The QX30 Sport executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Terrain Denali AWD (26.1 seconds @ .71 average G’s vs. 27.5 seconds @ .64 average G’s).

For better maneuverability, the QX30 AWD’s turning circle is .8 feet tighter than the Terrain w/17” wheels’ (36.6 feet vs. 37.4 feet). The QX30’s turning circle is 4.3 feet tighter than the Terrain w/19” wheels’ (37.3 feet vs. 41.6 feet).

For greater off-road capability the QX30 has a 1.1 inches greater minimum ground clearance than the Terrain SLE (8 vs. 6.9 inches), allowing the QX30 to travel over rougher terrain without being stopped or damaged. The QX30’s minimum ground clearance is .1 inch higher than on the Terrain SLT/Denali (8 vs. 7.9 inches).

Chassis

The QX30 is 8.1 inches shorter than the Terrain, making the QX30 easier to handle, maneuver and park in tight spaces.

The QX30 is 7.4 inches shorter in height than the Terrain, making the QX30 much easier to wash and garage and drive (lower center of gravity).

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the QX30. The Terrain doesn’t offer locking storage for small valuables.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than GMC. J.D. Power ranks Infiniti first in service department satisfaction. With a 33% lower rating, GMC is ranked 13th.

Ergonomics

Unlike the driver-only memory seat and mirrors optional at extra cost in the Terrain (except SL/SLE), the QX30 Luxe/Sport/Essential has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The QX30’s front power windows 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 front passenger window doesn’t close automatically.

If the windows are left open on the QX30 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

The QX30 Sport/Essential’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Terrain’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the QX30 Sport/Essential to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Terrain doesn’t offer heated windshield washer nozzles.

To help drivers see further while navigating curves, the QX30 Sport/Essential has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Terrain doesn’t offer cornering lights.

The QX30 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 QX30’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 QX30 (except Pure)’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.

Economic Advantages

Insurance will cost less for the QX30 owner. The Car Book by Jack Gillis rates the QX30 with a number “5” insurance rate while the Terrain is rated higher at a number “10” rate.

The QX30 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the QX30 will retain 53.6% to 54.72% of its original price after five years, while the Terrain only retains 45.99% to 49.47%.
