The Stelvio Quadrifoglio’s front to rear weight distribution is more even (52.9% to 47.1%) than the AMG GLC Coupe’s (55.1% to 44.9%). This gives the Stelvio Quadrifoglio more stable handling and braking.

The Stelvio Quadrifoglio’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The AMG GLC Coupe’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To improve rear visibility by keeping the rear window clear, the Stelvio Quadrifoglio has a standard rear wiper. The AMG GLC Coupe doesn’t offer a rear wiper.

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 Quadrifoglio has standard headlight washers to keep headlight output high. The AMG GLC Coupe doesn’t offer headlight washers.

On extremely cold winter days, the Stelvio Quadrifoglio’s standard (except w/Sparco Racing Seats) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The AMG GLC Coupe doesn’t offer a heated steering wheel.
