The Stelvio Ti’s optional 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 QX50 doesn’t offer a driver alert monitor.

Both the Stelvio and the QX50 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.

The engine in the Stelvio has a single overhead cam for simplicity. The engine in the QX50 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 that can degrade battery life. By keeping the Stelvio’s battery 20 to 30 degrees cooler, its life is increased by years. The QX50’s battery is in the hot engine compartment.

In heavy traffic or at stoplights the Stelvio’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 QX50 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Alfa Romeo Stelvio uses regular unleaded gasoline (premium recommended for maximum performance). The QX50 requires premium, which can cost 20 to 55 cents more per gallon.

The Stelvio has almost a gallon more fuel capacity than the QX50 (16.9 vs. 16 gallons), for longer range between fill-ups.

The Stelvio offers an optional 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 QX50; 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 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 QX50’s suspension doesn’t offer adjustable shock absorbers.

The Stelvio’s front to rear weight distribution is more even (50% to 50%) than the QX50’s (57.9% to 42.1%). This gives the Stelvio more stable handling and braking.

The Stelvio’s standard towing capacity is much higher than the QX50’s (3000 vs. 0 pounds).

The engine in the Stelvio is mounted longitudinally (North-South), instead of sideways, as in the QX50. This makes it easier to service and maintain, because the accessory belts are in front.

The Stelvio’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the QX50, and is not available on all models.

The power windows standard on both the Stelvio and the QX50 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 QX50 prevents the driver from operating the other windows just as it does the other passengers.

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 QX50’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are optional on the Stelvio to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The QX50 doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Stelvio’s headlight performance “Very Good,” a higher rating than the QX50’s headlights, which were rated “Good.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Stelvio offers available headlight washers to keep headlight output high. The QX50 doesn’t offer headlight washers.

The Stelvio’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential/Sensory/Autograph.

The Stelvio offers optional 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 QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Stelvio and the QX50 offer available heated front seats. The Stelvio also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Alfa Romeo Stelvio offers an optional wireless phone charging system (Qi) in the center console. The QX50 doesn’t offer wireless personal charging.

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 QX50 doesn’t offer a house-current electrical outlet.
