Safety

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Stelvio. But it costs extra on the QX30.

To help make backing safer, the Stelvio’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The QX30 doesn’t offer a cross-path warning system.

Compared to metal, the Stelvio’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Infiniti QX30 has a metal gas tank.

Both the Stelvio and the QX30 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and front parking sensors.

The Alfa Romeo Stelvio weighs 517 to 712 pounds more than the Infiniti QX30. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Reliability

The engine in the Stelvio has a single overhead cam for simplicity. The engine in the QX30 has dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

The battery on the Stelvio is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the Stelvio’s battery 20 to 30 degrees cooler, its life is increased by years. The QX30’s battery is in the hot engine compartment.

Engine

The Stelvio’s 2.0 turbo 4 cyl. produces 72 more horsepower (280 vs. 208) and 48 lbs.-ft. more torque (306 vs. 258) than the QX30’s 2.0 turbo 4 cyl.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Alfa Romeo Stelvio uses regular unleaded gasoline (premium recommended for maximum performance). The QX30 requires premium, which can cost 20 to 55 cents more per gallon.

The Stelvio has 3.7 gallons more fuel capacity than the QX30 FWD’s standard fuel tank (16.9 vs. 13.2 gallons), for longer range between fill-ups. The Stelvio has 2.1 gallons more fuel capacity than the QX30 AWD’s standard fuel tank (16.9 vs. 14.8 gallons).

Transmission

An eight-speed automatic is standard on the Alfa Romeo Stelvio, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX30.

Brakes and Stopping

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

 

Stelvio

QX30

Front Rotors

13 inches

12.6 inches

Rear Rotors

12.5 inches

11.6 inches

The Stelvio’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the QX30 are solid, not vented.

Tires and Wheels

For better traction, the Stelvio’s optional tires are larger than the largest tires available on the QX30 (255/45R20 vs. 235/50R18).

For better ride, handling and brake cooling the Stelvio offers optional 20-inch wheels. The QX30’s largest wheels are only 19-inches.

Suspension and Handling

The Stelvio offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX30’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Stelvio’s wheelbase is 4.7 inches longer than on the QX30 (111 inches vs. 106.3 inches).

For better handling and stability, the track (width between the wheels) on the Stelvio is 1.7 inches wider in the front and 3 inches wider in the rear than the average track on the QX30.

The Stelvio’s front to rear weight distribution is more even (50% to 50%) than the QX30’s (59.7% to 40.3%). This gives the Stelvio more stable handling and braking.

For greater off-road capability the Stelvio has a greater minimum ground clearance than the QX30 (8.1 vs. 8 inches), allowing the Stelvio to travel over rougher terrain without being stopped or damaged.

Passenger Space

The Stelvio has 1.8 inches more front headroom and 1.4 inches more rear headroom than the QX30.

Cargo Capacity

The Stelvio has a larger cargo area with its rear seat folded than the QX30 with its rear seat folded (56.5 vs. 34 cubic feet).

To make loading and unloading groceries and cargo easier, especially for short adults, the Stelvio has a standard power cargo door, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The QX30 doesn’t offer a power cargo door.

Towing

The Stelvio has a 3000 lbs. towing capacity. The QX30 has no towing capacity.

Servicing Ease

The Stelvio uses gas struts to support the hood for easier service access. The QX30 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 Stelvio is mounted longitudinally (North-South), instead of sideways, as in the QX30. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The Stelvio has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The QX30 doesn’t offer a remote starting system.

The power windows standard on both the Stelvio and the QX30 have locks to prevent small children from operating them. When the lock on the Stelvio is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX30 prevents the driver from operating the other windows just as it does the other passengers.

The Stelvio’s front and rear power windows all 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 QX30’s rear power window switches have to be held the entire time to open or close them fully.

The Stelvio’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 QX30’s standard manually variable intermittent wipers have to be constantly adjusted.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Stelvio has standard extendable sun visors. The QX30 doesn’t offer extendable visors.

On extremely cold Winter days, the Stelvio’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The QX30 doesn’t offer a heated steering wheel.

The Stelvio offers an optional 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX30 doesn’t offer a house-current electrical outlet.
