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 Hyundai Tucson doesn’t offer pretensioners for the rear seat belts.

Both the QX30 and the Tucson have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the QX30’s reliability 11 points higher than the Tucson.

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 Hyundai vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 4 more problems per 100 vehicles, Hyundai is ranked 6th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Infiniti 4 places higher in reliability than Hyundai.

Engine

The QX30’s 2.0 turbo 4 cyl. produces 44 more horsepower (208 vs. 164) and 107 lbs.-ft. more torque (258 vs. 151) than the Tucson SE/Value’s standard 2.0 DOHC 4 cyl. The QX30’s 2.0 turbo 4 cyl. produces 27 more horsepower (208 vs. 181) and 83 lbs.-ft. more torque (258 vs. 175) than the Tucson SEL/Sport/Limited’s standard 2.4 DOHC 4 cyl.

In heavy traffic or at stoplights the QX30’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 Tucson doesn’t offer an automatic engine start/stop system.

Motor Trend

Tires and Wheels

For better traction, the QX30 has larger tires than the Tucson (235/50R18 vs. 225/60R17).

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 Tucson SE/Value’s standard 60 series tires.

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

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 Tucson doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the QX30’s wheelbase is 1.2 inches longer than on the Tucson (106.3 inches vs. 105.1 inches).

The QX30 Sport handles at .88 G’s, while the Tucson Limited AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The QX30 Sport executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Tucson SE (26.1 seconds @ .71 average G’s vs. 27.9 seconds @ .6 average G’s).

For greater off-road capability the QX30 has a 1.6 inches greater minimum ground clearance than the Tucson (8 vs. 6.4 inches), allowing the QX30 to travel over rougher terrain without being stopped or damaged.

Chassis

To almost totally eliminate engine vibration in the passenger area, the QX30 has a liquid-filled front engine mount. The liquid helps further dampen engine harshness. The Tucson uses conventional solid rubber engine mounts.

Passenger Space

The front step up height for the QX30 is 2.6 inches lower than the Tucson (16.4” vs. 19”). The QX30’s rear step up height is 2.8 inches lower than the Tucson’s (17.2” vs. 20”).

Cargo Capacity

A low lift-over cargo hatch design makes loading and unloading the QX30 easier. The QX30’s cargo hatch lift-over height is 28.1 inches, while the Tucson’s liftover is 29.3 inches.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the QX30. The Tucson 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 Hyundai. J.D. Power ranks Infiniti first in service department satisfaction. With a 62% lower rating, Hyundai is ranked 22nd.

Ergonomics

When three different drivers share the QX30 Luxe/Sport/Essential, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions and outside mirror angle. The Tucson doesn’t offer a memory system.

The QX30 Luxe/Sport/Essential’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 Tucson doesn’t offer an easy entry system.

The QX30’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Tucson’s standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens 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 Tucson can only operate the windows from inside the vehicle, with the ignition on.

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 Tucson doesn’t offer heated windshield washer nozzles.

When the QX30 Luxe/Sport/Essential is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Tucson’s mirror doesn’t automatically adjust for backing.

The QX30 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 Tucson offers an automatic rear view mirror, but its side mirrors don’t dim.

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 is only available on the Tucson SEL/Sport/Limited.

Both the QX30 and the Tucson offer rear vents. For greater rear passenger comfort, the QX30 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Tucson doesn’t offer rear air conditioning vents, only heat vents.

The QX30 (except Pure/Luxe)’s optional Intelligent Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Tucson doesn’t offer an automated parking system.

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 Tucson is rated higher at a number “10” rate.
