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 Cadillac CT5-V 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 CT5-V doesn’t offer pre-crash pretensioners.

The AMG E-Class Sedan has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The CT5-V doesn’t offer front seat center airbags.

The CT5-V doesn’t offer a power trunk, so its trunk has to be closed manually.

Unlike the driver-only memory system in the CT5-V, the AMG E-Class Sedan 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.
