Compare the2024 Infiniti Q50VS 2024 Alfa Romeo Giulia Quadrifoglio

For enhanced safety, the front seat shoulder belts of the Infiniti Q50 are height-adjustable to accommodate a wide variety of driver and passenger heights.

The Giulia Quadrifoglio doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Giulia Quadrifoglio doesn’t offer run-flat tires.

When the Q50 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers.
