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 BMW 2 Series 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 2 Series 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 2 Series doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG CLA. But it costs extra on the 2 Series.
Both the AMG CLA and 2 Series 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 2 Series’ Cross Traffic Warning doesn’t automatically brake.
Both the AMG CLA and the 2 Series 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, driver alert monitors, available lane departure warning systems and around view monitors.
