Compare the2025 Mercedes AMG GLAVS 2024 Alfa Romeo Stelvio Quadrifoglio

For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLA have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Alfa Romeo Stelvio Quadrifoglio doesn’t offer pretensioners for its rear seat belts.

The AMG GLA’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Stelvio Quadrifoglio doesn’t offer pre-crash pretensioners.

The AMG GLA’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Stelvio Quadrifoglio doesn’t offer a whiplash protection system.

The AMG GLA offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Stelvio Quadrifoglio doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The AMG GLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Stelvio Quadrifoglio 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 AMG GLA and Stelvio Quadrifoglio have rear cross-traffic warning, but the AMG GLA has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Stelvio Quadrifoglio’s Rear Cross-Path Detection doesn’t automatically brake.

Both the AMG GLA and the Stelvio Quadrifoglio have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.

There are over 3 times as many Mercedes dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the AMG GLA’s warranty.

On the EPA test cycle the AMG GLA 35 gets better fuel mileage than the Stelvio Quadrifoglio (22 city/28 hwy vs. 17 city/23 hwy).

Regenerative brakes improve the AMG GLA’s fuel efficiency by converting inertia back into energy instead of wasting it. The Stelvio Quadrifoglio doesn’t offer a regenerative braking system.

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

The AMG GLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Stelvio Quadrifoglio doesn’t offer an SMG or a conventional manual transmission.

The AMG GLA stops shorter than the Stelvio Quadrifoglio:

The AMG GLA’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Stelvio Quadrifoglio’s optional 40 series front tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the AMG GLA can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Stelvio Quadrifoglio doesn’t offer run-flat tires.

The AMG GLA’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Stelvio Quadrifoglio doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the AMG GLA is 2.5 inches wider in the front than on the Stelvio Quadrifoglio.

The AMG GLA 35 handles at .94 G’s, while the Stelvio Quadrifoglio pulls only .92 G’s of cornering force in a Motor Trend skidpad test.

The Mercedes AMG GLA may be more efficient, handle and accelerate better because it weighs about 450 pounds less than the Alfa Romeo Stelvio Quadrifoglio.

The AMG GLA has 4.4 inches more front legroom and 6.1 inches more rear legroom than the Stelvio Quadrifoglio.

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

The AMG GLA has a larger cargo volume than the Stelvio Quadrifoglio with its rear seat up (19 vs. 18.5 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the AMG GLA easier. The AMG GLA’s cargo hatch lift-over height is 27.2 inches, while the Stelvio Quadrifoglio’s liftover is 28.5 inches.

Unlike the driver-only memory seat and mirrors in the Stelvio Quadrifoglio, the AMG GLA has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The AMG GLA offers an optional heads-up display that projects speed, tachometer 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 Quadrifoglio doesn’t offer a heads-up display.

If the windows are left open on the AMG GLA 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 Quadrifoglio can only operate the windows from inside the vehicle, with the ignition on.

The AMG GLA’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Keyless-Enter-n-Go standard on the Stelvio Quadrifoglio doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

Heated windshield washer fluid is optional on the AMG GLA to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Stelvio Quadrifoglio doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

The AMG GLA’s LED headlights produce a white, bright light using less electricity than the Stelvio Quadrifoglio’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 AMG GLA is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Stelvio Quadrifoglio’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the AMG GLA keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Stelvio Quadrifoglio doesn’t offer air-conditioned seats.

The AMG GLA’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Stelvio Quadrifoglio doesn’t offer an automated parking system.

The AMG GLA will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the AMG GLA will retain 53.9% to 54.09% of its original price after five years, while the Stelvio Quadrifoglio only retains 52.24%.

The Mercedes GLA outsold the Alfa Romeo Stelvio by over two to one during 2023.
