Compare the2025 BMW X4VS 2024 Alfa Romeo Stelvio

The X4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Stelvio doesn’t offer pre-crash pretensioners.

The X4 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Stelvio doesn’t offer a whiplash protection system.

The X4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Stelvio doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The X4 offers an optional Active Park Distance Control 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 X4. But it costs extra on the Stelvio.

The X4 offers an optional Surround View 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 X4 and the Stelvio have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 X4’s corrosion warranty is 7 years longer than the Stelvio’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X4 for 3 years and 36,000 miles. BMW 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 almost 3 times as many BMW dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the X4’s warranty.

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 X4’s reliability 20 points higher than the Stelvio.

J.D. Power and Associates rated the X4 first among compact premium suvs in their 2024 Initial Quality Study. The Stelvio was rated second.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Alfa Romeo vehicles. With 20 fewer problems per 100 vehicles, JD Power ranks BMW higher than Alfa Romeo.

The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 102 more horsepower (382 vs. 280) and 63 lbs.-ft. more torque (369 vs. 306) than the Stelvio’s 2.0 turbo 4-cylinder.

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Stelvio doesn’t offer a regenerative braking system.

For better stopping power the X4 M40i’s brake rotors are larger than those on the Stelvio:

The X4 stops much shorter than the Stelvio:

For better traction, the X4 has larger standard tires than the Stelvio (245/50R19 vs. 235/60R18).

The X4’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 Stelvio Sprint’s standard 60 series tires. The X4’s optional 275/35R21 rear tires have a lower 35 series profile than the Stelvio’s optional 40 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Stelvio Sprint.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 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.

For a smoother ride and more stable handling, the X4’s wheelbase is 1.9 inches longer than on the Stelvio (112.8 inches vs. 110.9 inches).

The X4 M40i handles at .89 G’s, while the Stelvio Ti AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Stelvio Ti AWD (25.6 seconds @ .73 average G’s vs. 26.9 seconds @ .67 average G’s).

The front grille of the X4 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Stelvio doesn’t offer active grille shutters.

The X4 has 4.1 inches more front legroom and 3.6 inches more rear legroom than the Stelvio.

For enhanced passenger comfort on long trips the X4’s rear seats recline. The Stelvio’s rear seats don’t recline.

The X4 offers an optional heads-up display that projects speed, warning, 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 X4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote or with the driver’s door power window switch. The driver of the Stelvio can only operate the windows from inside the vehicle, with the ignition on.

The X4’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 X4 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 Stelvio’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the X4 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 X4’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Stelvio doesn’t offer an automated parking system.

J.D. Power and Associates rated the X4 first among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Stelvio isn’t in the top three.

The BMW X4 outsold the Alfa Romeo Stelvio by 79% during 2023.
