The Terrain 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.

Transmission

A nine-speed automatic is standard on the GMC Terrain, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Stelvio.

Brakes and Stopping

The Terrain stops shorter than the Stelvio:

Tires and Wheels

The Terrain 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.

Suspension and Handling

For better maneuverability, the Terrain w/17” wheels’ turning circle is 1.1 feet tighter than the Stelvio’s (37.4 feet vs. 38.5 feet).

Chassis

The GMC Terrain may be more efficient, handle and accelerate better because it weighs about 250 to 450 pounds less than the Alfa Romeo Stelvio.

The front grille of the Terrain 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 Terrain 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.

Passenger Space

The Terrain has 4.3 inches more front legroom and 7.8 inches more rear legroom than the Stelvio.

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

Cargo Capacity

The Terrain has a much larger cargo volume with its rear seat up than the Stelvio with its rear seat up (29.6 vs. 18.5 cubic feet). The Terrain has a much larger cargo volume with its rear seat folded than the Stelvio with its rear seat folded (63.3 vs. 56.5 cubic feet).

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

Towing

Maximum trailer towing in the Alfa Romeo Stelvio is limited to 3000 pounds. The Terrain offers up to a 3500 lbs. towing capacity.

Ergonomics

The Terrain’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.

On a hot day the Terrain’s driver can lower all 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 Terrain 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.

Optional air-conditioned seats in the Terrain Denali 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the GMC Terrain Denali has a standard wireless phone charging system (Qi) in the center console. The Stelvio doesn’t offer wireless personal charging.

The Terrain Denali’s optional Automatic Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Stelvio doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the Terrain owner. The Complete Car Cost Guide estimates that insurance for the Terrain will cost $1770 to $3255 less than the Stelvio over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the GMC Terrain will be $9194 to $17200 less than for the Alfa Romeo Stelvio.

Recommendations

The GMC Terrain outsold the Alfa Romeo Stelvio by over 9 to one during 2018.
