For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC 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 doesn’t offer pretensioners for the rear seat belts.

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

The GLC has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Stelvio doesn’t offer a whiplash protection system.

The GLC offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Stelvio 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.

The GLC’s 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 Stelvio doesn’t offer a driver alert monitor.

The GLC has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to 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 GLC and the Stelvio 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, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GLC its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The Stelvio has not been tested, yet.

The GLC’s corrosion warranty is 1 year longer than the Stelvio’s (5 vs. 4 years).

There are over 2 times as many Mercedes dealers as there are Alfa Romeo dealers, which makes it much easier should you ever need service under the GLC’s warranty.

J.D. Power and Associates rated the GLC third among compact premium suvs in their 2019 Initial Quality Study. The Stelvio isn’t in the top three in its category.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Alfa Romeo vehicles. J.D. Power ranks Mercedes 12th in initial quality. With 24 more problems per 100 vehicles, Alfa Romeo is ranked 29th.

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

The GLC has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLC’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 doesn’t offer a load leveling suspension.

The GLC’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 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLC’s wheelbase is 2.1 inches longer than on the Stelvio (113.1 inches vs. 111 inches).

The GLC 300 4MATIC handles at .83 G’s, while the Stelvio Ti AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The front grille of the GLC 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 GLC has a larger cargo volume than the Stelvio with its rear seat up (19.4 vs. 18.5 cubic feet).

Unlike the driver-only memory seat and mirrors in the Stelvio, the GLC offers an optional 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 GLC offers an optional heads-up display that projects speed 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 doesn’t offer a heads-up display.

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

When the GLC 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’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the GLC 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 Mercedes GLC offers an optional wireless phone charging system (Qi) in the center console. The Stelvio doesn’t offer wireless personal charging.

The GLC’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Stelvio doesn’t offer an automated parking system.

The GLC will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLC will retain 44.66% to 45.7% of its original price after five years, while the Stelvio only retains 40.25% to 42.03%.
