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.

The RDX has standard AcuraLink, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Stelvio doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

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, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Pick Plus” for 2019, a rating granted to only 46 vehicles tested by the IIHS. The Stelvio has not been tested, yet.

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.

The RDX’s corrosion warranty is 1 year longer than the Stelvio’s (5 vs. 4 years).

There are over 56 percent more Acura dealers than there are Alfa Romeo dealers, which makes it much easier should you ever need service under the RDX’s warranty.

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.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Acura RDX higher (6 out of 10) than the Alfa Romeo Stelvio (3). This means the RDX produces up to 23.4 pounds less smog-producing pollutants than the Stelvio every 15,000 miles.

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Stelvio’s standard 60 series tires. The RDX A-Spec’s tires have a lower 40 series profile than the Stelvio’s optional 45 series tires.

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

Pressing a switch automatically lowers the RDX’s rear seats, to make changing between passengers and cargo easier. The Stelvio doesn’t offer automatic folding seats.

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.

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.

Optional air-conditioned seats in the RDX 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 $2840 to $3785 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 51.89% to 53.05% of its original price after five years, while the Stelvio only retains 48.22% to 48.46%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura RDX will be $7729 to $10288 less than for the Alfa Romeo Stelvio.
