Over 200 people are killed each year when backed over by motor vehicles.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Giulia Quadrifoglio, the AMG GT 4-Door 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 GT 4-Door 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 Giulia Quadrifoglio doesn’t offer a heads-up display.

If the windows are left open on the AMG GT 4-Door 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 Giulia Quadrifoglio can only operate the windows from inside the vehicle, with the ignition on.

Heated windshield washer fluid is standard on the AMG GT 4-Door to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Giulia Quadrifoglio doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

A manual rear sunshade is optional in the AMG GT 4-Door to help block heat and glare for the rear passengers. The Giulia Quadrifoglio doesn’t offer a rear sunshade.

When the AMG GT 4-Door 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 Giulia Quadrifoglio’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the AMG GT 4-Door keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Giulia Quadrifoglio doesn’t offer air-conditioned seats.
