For enhanced safety, the front and second-row seat shoulder belts of the Mercedes AMG GLE 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 GLE’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 GLE has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The Stelvio Quadrifoglio doesn’t offer a whiplash protection system.

The AMG GLE offers optional Post-Collision Brake, which automatically apply 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.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The AMG GLE has Car-to-X, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Stelvio Quadrifoglio doesn’t offer a system that can receive automated systems from other vehicles.

The AMG GLE has a standard 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 GLE and Stelvio Quadrifoglio have rear cross-traffic warning, but the AMG GLE 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 GLE and the Stelvio Quadrifoglio have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

The Mercedes AMG GLE weighs 972 to 1259 pounds more than the Alfa Romeo Stelvio Quadrifoglio. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the AMG GLE its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 67 vehicles tested by the IIHS. The Stelvio Quadrifoglio has not been tested, yet.

Warranty

There are almost 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 GLE’s warranty.

Reliability

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Alfa Romeo With 50 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Alfa Romeo.

Engine

The AMG GLE 63 S’ standard 4.0 turbo V8 hybrid produces 98 more horsepower (603 vs. 505) and 184 lbs.-ft. more torque (627 vs. 443) than the Stelvio Quadrifoglio’s 2.9 turbo V6.

As tested in Car and Driver the AMG GLE 63 S 4.0 turbo V8 hybrid is faster than the Alfa Romeo Stelvio Quadrifoglio:

	AMG GLE	Stelvio Quadrifoglio
Zero to 60 MPH	3.2 sec	3.3 sec
Zero to 100 MPH	8.1 sec	8.4 sec
Quarter Mile	11.6 sec	11.8 sec
Speed in 1/4 Mile	118 MPH	117 MPH

Fuel Economy and Range

On the EPA test cycle the AMG GLE 53 gets better fuel mileage than the Stelvio Quadrifoglio (18 city/23 hwy vs. 17 city/23 hwy).

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

The AMG GLE has 5.6 gallons more fuel capacity than the Stelvio Quadrifoglio (22.5 vs. 16.9 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLE higher (5 to 7 out of 10) than the Alfa Romeo Stelvio Quadrifoglio (3). This means the AMG GLE produces up to 24.5 pounds less smog-producing pollutants than the Stelvio Quadrifoglio every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Mercedes AMG GLE, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Stelvio Quadrifoglio.

Brakes and Stopping

For better stopping power the AMG GLE’s front brake rotors are larger than those on the Stelvio Quadrifoglio:

	AMG GLE 53	AMG GLE 63 S CCB	Stelvio Quadrifoglio
Front Rotors	15.8 inches	16.5 inches	14.2 inches
Rear Rotors	13.6 inches	14.6 inches	13.8 inches

The AMG GLE offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Stelvio Quadrifoglio doesn’t offer ceramic brake rotors.

Tires and Wheels

For better traction, the AMG GLE has larger standard tires than the Stelvio Quadrifoglio (275/50R20 vs. 255/45R20). The AMG GLE’s optional tires are larger than the largest tires available on the Stelvio Quadrifoglio (F:285/40R22 & R:325/35R22 vs. F:255/45R20 & R:285/40R20).

For better ride, handling and brake cooling the AMG GLE offers optional 22-inch wheels. The Stelvio Quadrifoglio’s largest wheels are only 21-inches.

The AMG GLE has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Stelvio Quadrifoglio; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The AMG GLE offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Stelvio Quadrifoglio doesn’t offer an active sway bar system.

The front and rear suspension of the AMG GLE uses air springs for a smoother, controlled ride than the Stelvio Quadrifoglio, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG GLE offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Alfa Romeo doesn’t offer an active suspension on the Stelvio Quadrifoglio.

The AMG GLE has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG GLE’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Stelvio Quadrifoglio doesn’t offer a load leveling suspension.

The AMG GLE’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 a smoother ride and more stable handling, the AMG GLE’s wheelbase is 7 inches longer than on the Stelvio Quadrifoglio (117.9 inches vs. 110.9 inches).

For better handling and stability, the average track (width between the wheels) on the AMG GLE is 5.2 inches wider in the front and 4.5 inches wider in the rear than the track on the Stelvio Quadrifoglio.

Passenger Space

The AMG GLE offers optional seating for 7 passengers; the Stelvio Quadrifoglio can only carry 5.

The AMG GLE has .3 inches more front headroom, 3.7 inches more front legroom, 1.8 inches more front shoulder room, 9 inches more rear legroom and 2.3 inches more rear shoulder room than the Stelvio Quadrifoglio.

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

Cargo Capacity

The AMG GLE has a much larger cargo volume with its rear seat up than the Stelvio Quadrifoglio with its rear seat up (33.3 vs. 18.5 cubic feet). The AMG GLE has a much larger cargo volume with its rear seat folded than the Stelvio Quadrifoglio with its rear seat folded (74.9 vs. 56.5 cubic feet).

Towing

The AMG GLE has a 7700 lbs. towing capacity. The Stelvio Quadrifoglio has no towing capacity.

Optional Trailer Stability Assist on the AMG GLE uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Stelvio Quadrifoglio doesn’t offer electronic trailer sway control.

Ergonomics

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

The AMG GLE 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 GLE the driver can close them all at the outside door handle or from a distance using the remote (remote must be aimed at door sensor). 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.

Heated windshield washer fluid is optional on the AMG GLE 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 GLE’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.

To better shield the driver and front passenger’s vision, the AMG GLE has standard dual-element sun visors that can block glare from two directions simultaneously. The Stelvio Quadrifoglio doesn’t offer secondary sun visors.

Manual rear side window sunshades are available in the AMG GLE to help block heat and glare for the rear passengers. The Stelvio Quadrifoglio doesn’t offer rear side window sunshades.

When the AMG GLE 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.

Standard air-conditioned seats in the AMG GLE 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 GLE offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Stelvio Quadrifoglio.

The AMG GLE’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.

Recommendations

The Mercedes GLE outsold the Alfa Romeo Stelvio by over 8 to one during 2022.
