Compare the2025 Acura RDXVS 2025 Alfa Romeo Stelvio

The RDX Advance has a standard Surround-View Camera System 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 RDX 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, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, 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 Acura RDX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Stelvio has not yet been evaluated by the IIHS for 2024.

Acura’s powertrain warranty covers the RDX 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.

There are over 2 times as many Acura dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the RDX’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 RDX’s reliability 50 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 Acura vehicles are better in initial quality than Alfa Romeo vehicles. J.D. Power ranks Acura above average in initial quality. With 33 more problems per 100 vehicles, Alfa Romeo is rated below average.

The RDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Stelvio doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Stelvio.

The RDX stops much shorter than the Stelvio:

The RDX 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.

For greater off-road capability the RDX has a greater minimum ground clearance than the Stelvio (8.2 vs. 8.1 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The RDX 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 RDX has 6.4 cubic feet more passenger volume than the Stelvio (104 vs. 97.6).

The RDX has 5 inches more front legroom, 2.2 inches more front shoulder room, 6.5 inches more rear legroom and .6 inches more rear shoulder room than the Stelvio.

The RDX has a much larger cargo volume with its rear seat up than the Stelvio with its rear seat up (31.1 vs. 18.5 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Stelvio with its rear seat folded (79.8 vs. 56.5 cubic feet).

J.D. Power and Associates surveys of service recipients show that Acura service is better than Alfa Romeo. J.D. Power ranks Acura 9th in service department satisfaction (above the industry average). With a 3% lower rating, Alfa Romeo is ranked 11th.

The RDX Advance has a standard heads-up display that projects speed and navigation instruction 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 RDX 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. The driver of the Stelvio can only operate the windows from inside the vehicle, with the ignition on.

The RDX’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 RDX 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 RDX A-Spec/Advance 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.

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $2730 to $4605 less than the Stelvio over a five-year period.

The RDX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the RDX will retain 53.7% to 55% of its original price after five years, while the Stelvio only retains 51.75% to 52.66%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura RDX will be $6441 to $9820 less than for the Alfa Romeo Stelvio.
