For enhanced safety, the front seat shoulder belts of the Alfa Romeo Stelvio are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Terrain doesn’t offer height-adjustable front seat belts.

The Stelvio Ti’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.

Both the Stelvio and the Terrain have standard driver and passenger frontal airbags, front side-impact 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, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.

The Stelvio’s corrosion warranty is unlimited miles longer than the Terrain’s (unlimited vs. 100,000 miles).

The engine in the Stelvio has a single overhead cam for simplicity. The engines in the Terrain have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

The battery on the Stelvio is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Stelvio’s battery 20 to 30 degrees cooler, its life is increased by years. The Terrain’s battery is in the hot engine compartment.

The Stelvio’s 2.0 turbo 4 cyl. produces 110 more horsepower (280 vs. 170) and 103 lbs.-ft. more torque (306 vs. 203) than the Terrain’s standard 1.5 turbo 4 cyl. The Stelvio’s 2.0 turbo 4 cyl. produces 28 more horsepower (280 vs. 252) and 46 lbs.-ft. more torque (306 vs. 260) than the Terrain’s optional 2.0 turbo 4 cyl.

For better traction, the Stelvio has larger standard tires than the Terrain (235/60R18 vs. 225/65R17). The Stelvio’s optional tires are larger than the largest tires available on the Terrain (255/45R20 vs. 235/50R19).

The Stelvio’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Terrain’s standard 65 series tires. The Stelvio’s optional tires have a lower 45 series profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the Stelvio has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Terrain. The Stelvio’s optional 20-inch wheels are larger than the 19-inch wheels optional on the Terrain.

Suspension and Handling

The Stelvio has standard front and rear stabilizer bars, which help keep the Stelvio flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

The Stelvio offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Terrain’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Stelvio’s wheelbase is 3.6 inches longer than on the Terrain (110.9 inches vs. 107.3 inches).

For better handling and stability, the track (width between the wheels) on the Stelvio is 1.2 inches wider in the front and 2.5 inches wider in the rear than on the Terrain.

The Stelvio Ti AWD handles at .82 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Stelvio Ti AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Terrain Denali AWD (26.9 seconds @ .67 average G’s vs. 27.5 seconds @ .64 average G’s).

For greater off-road capability the Stelvio has a 1.2 inches greater minimum ground clearance than the Terrain SLE (8.1 vs. 6.9 inches), allowing the Stelvio to travel over rougher terrain without being stopped or damaged. The Stelvio’s minimum ground clearance is .2 inch higher than on the Terrain SLT/Denali (8.1 vs. 7.9 inches).

The Stelvio uses gas struts to support the hood for easier service access. The Terrain uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the Stelvio is mounted longitudinally (North-South), instead of sideways, as in the Terrain. This makes it easier to service and maintain, because the accessory belts are in front.

The Stelvio’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Terrain, and is not available on all models.

The Stelvio’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Terrain’s passenger windows don’t close automatically.

The Stelvio’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Terrain’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are optional on the Stelvio to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Terrain doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Stelvio’s headlight performance “Very Good,” a higher rating than the Terrain’s headlights, which were rated “Good.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Stelvio offers available headlight washers to keep headlight output high. The Terrain doesn’t offer headlight washers.

To help drivers see further while navigating curves, the Stelvio has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Terrain doesn’t offer cornering lights.

The Stelvio has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Terrain and isn’t available on the Terrain SL.

The Stelvio’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Terrain SL doesn’t offer automatic air conditioning.

The Stelvio’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Terrain’s available navigation system doesn’t offer real-time traffic updates.
