For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG CLA 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 CLA’s optional 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.
The AMG CLA’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Giulia Quadrifoglio doesn’t offer a whiplash protection system.
The AMG CLA offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Giulia Quadrifoglio doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The AMG CLA has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Giulia Quadrifoglio doesn’t offer all-wheel drive.
The AMG CLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Giulia Quadrifoglio only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the AMG CLA and Giulia Quadrifoglio have rear cross-traffic warning, but the AMG CLA has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Giulia Quadrifoglio’s Rear Cross-Path Detection doesn’t automatically brake.
Both the AMG CLA and the Giulia Quadrifoglio have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
