For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG E-Class Sedan 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 Giulia Quadrifoglio doesn’t offer pretensioners for its rear seat belts.
The AMG E-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Giulia Quadrifoglio doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Mercedes AMG E-Class Sedan are height-adjustable to accommodate a wide variety of driver and passenger heights.
