Compare the2025 Infiniti QX55VS 2024 Alfa Romeo Stelvio

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX55 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 Alfa Romeo Stelvio doesn’t offer pretensioners for its rear seat belts.

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 QX55 are reminded to check the back seat if they opened the rear door before starting out. The Stelvio doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The QX55 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Stelvio doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the Stelvio.

The QX55 Essential/Sensory has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Stelvio only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the QX55 and the Stelvio have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

The QX55 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Stelvio’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX55 2 years and 20,000 miles longer than Alfa Romeo covers the Stelvio. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Stelvio ends after only 4 years or 50,000 miles.

The QX55’s corrosion warranty is 2 years longer than the Stelvio’s (7 vs. 5 years).

Infiniti pays for scheduled maintenance on the QX55 for 3 years and 45000 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Alfa Romeo only pays for the first scheduled maintenance visit on the Stelvio.

There are over 62 percent more Infiniti dealers than there are Alfa Romeo dealers, which makes it much easier should you ever need service under the QX55’s warranty.

To reliably start during all conditions and help handle large electrical loads, the QX55 has a standard 720-amp battery. The Stelvio’s 525-amp battery isn’t as powerful.

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 QX55’s reliability 20 points higher than the Stelvio.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Alfa Romeo vehicles. J.D. Power ranks Infiniti above average in initial quality. With 39 more problems per 100 vehicles, Alfa Romeo is rated below average.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti QX55 higher (6 out of 10) than the Alfa Romeo Stelvio (5). This means the QX55 produces up to 6.9 pounds less smog-producing pollutants than the Stelvio every 15,000 miles.

The QX55 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Stelvio doesn’t offer a CVT.

The QX55 stops shorter than the Stelvio:

For better traction, the QX55 has larger tires than the Stelvio (255/45R20 vs. 235/60R18).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Stelvio Sprint’s standard 60 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Stelvio Sprint.

The QX55 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 Stelvio doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX55 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the Stelvio.

The QX55 Essential handles at .87 G’s, while the Stelvio Ti AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the QX55’s turning circle is 2.1 feet tighter than the Stelvio’s (36.4 feet vs. 38.5 feet).

For greater off-road capability the QX55 has a greater minimum ground clearance than the Stelvio (8.6 vs. 8.1 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged.

The QX55 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Stelvio doesn’t offer active noise cancellation.

The QX55 has 2.6 cubic feet more passenger volume than the Stelvio (100.2 vs. 97.6).

The QX55 has 3 inches more front legroom, .4 inches more front shoulder room, 6.8 inches more rear legroom and 1.1 inches more rear shoulder room than the Stelvio.

For enhanced passenger comfort on long trips the QX55’s rear seats recline. The Stelvio’s rear seats don’t recline.

The QX55 has a much larger cargo volume than the Stelvio with its rear seat up (26.9 vs. 18.5 cubic feet).

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Alfa Romeo. J.D. Power ranks Infiniti 6th in service department satisfaction (above the industry average). With a 15% lower rating, Alfa Romeo is ranked 11th.

The QX55 Sensory has a standard heads-up display that projects speed, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Stelvio doesn’t offer a heads-up display.

If the windows are left open on the QX55 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 Stelvio can only operate the windows from inside the vehicle, with the ignition on.

The QX55’s standard Infiniti Intelligent Key allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless-Enter-n-Go standard on the Stelvio doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The QX55’s LED headlights produce a white, bright light using less electricity than the Stelvio’s xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

When the QX55 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Stelvio’s mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the QX55 Essential/Sensory keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Stelvio doesn’t offer air-conditioned seats.

The Infiniti QX55 outsold the Alfa Romeo Stelvio by 78 units during 2023.
