The Regal TourX has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, 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 Regal TourX 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, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.


Buick’s powertrain warranty covers the Regal TourX 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 Regal TourX’s corrosion warranty is 2 years longer than the Stelvio’s (6 vs. 4 years).

There are over 13 times as many Buick dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the Regal TourX’s warranty.

Fuel Economy and Range

The Regal TourX 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.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Regal TourX higher (5 out of 10) than the Alfa Romeo Stelvio (3). This means the Regal TourX produces up to 16.5 pounds less smog-producing pollutants than the Stelvio every 15,000 miles.

Tires and Wheels

The Regal TourX’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Stelvio’s standard 60 series tires.

Suspension and Handling

The Regal TourX Essence handles at .88 G’s, while the Stelvio Ti pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The Regal TourX Essence executes Motor Trend’s “Figure Eight” maneuver quicker than the Stelvio Ti (26.2 seconds @ .69 average G’s vs. 26.9 seconds @ .67 average G’s).


The Buick Regal TourX may be more efficient, handle and accelerate better because it weighs about 150 to 300 pounds less than the Alfa Romeo Stelvio.

The Regal TourX is 7.6 inches shorter in height than the Stelvio, making the Regal TourX much easier to wash and garage and drive (lower center of gravity).

The Regal TourX 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.

As tested by Car and Driver, the interior of the Regal TourX Essence is quieter than the Stelvio:




At idle

40 dB

43 dB


69 dB

72 dB

70 MPH Cruising

65 dB

66 dB

Passenger Space

The Regal TourX has 5.5 inches more front legroom, .7 inches more rear headroom and 5 inches more rear legroom than the Stelvio.

Cargo Capacity

The Regal TourX has a much larger cargo area with its rear seat up than the Stelvio with its rear seat up (32.7 vs. 18.5 cubic feet). The Regal TourX has a much larger cargo area with its rear seat folded than the Stelvio with its rear seat folded (73.5 vs. 56.5 cubic feet).


The Regal TourX’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Stelvio has neither an oil pressure gauge nor a temperature gauge.

When the Regal TourX Essence with available tilt-down mirrors 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.

Model Availability

The Buick Regal comes in four door hatchback and station wagon bodystyles; the Alfa Romeo Stelvio isn’t available as a four door hatchback.


The Buick Regal outsold the Alfa Romeo Stelvio by over four to one during 2017.
