For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GLC 63 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 the rear seat belts.

The AMG GLC 63’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 GLC 63’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 Quadrifoglio doesn’t offer a driver alert monitor.

The AMG GLC 63 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 Quadrifoglio 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 AMG GLC 63 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, available lane departure warning systems and rear parking sensors.

A nine-speed automatic is standard on the Mercedes AMG GLC 63, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Stelvio Quadrifoglio.

For better traction, the AMG GLC 63 has larger tires than the Stelvio Quadrifoglio (F:265/45R20 & R:295/40R20 vs. F:255/45R20 & R:285/40R20).

The AMG GLC 63’s optional 265/40R21 front and 295/35R21 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Stelvio Quadrifoglio’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the AMG GLC 63 offers optional 21-inch wheels. The Stelvio Quadrifoglio’s largest wheels are only 20-inches.

The front and rear suspension of the AMG GLC 63 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 GLC 63 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG GLC 63’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 GLC 63’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 GLC 63’s wheelbase is 2.1 inches longer than on the Stelvio Quadrifoglio (113.1 inches vs. 111 inches).

For better handling and stability, the track (width between the wheels) on the AMG GLC 63 is 5.1 inches wider in the front and 2.4 inches wider in the rear than on the Stelvio Quadrifoglio.

Unlike the driver-only memory seat and mirrors in the Stelvio Quadrifoglio, the AMG GLC 63 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 GLC 63 offers an optional heads-up display that projects speed and other key instrumentation 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 GLC 63 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.

When the AMG GLC 63 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 GLC 63 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 GLC 63’s optional Active Parking Assist can parallel park by itself, with the driver only controlling speed with the brake pedal. The Stelvio Quadrifoglio doesn’t offer an automated parking system.
