For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG E-Class Cabriolet 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 8 Series doesn’t offer pretensioners for the rear seat belts.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG E-Class Cabriolet. But it costs extra on the 8 Series.
The AMG E-Class Cabriolet has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The 8 Series 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.
The AMG E-Class Cabriolet has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the 8 Series’ blind spot costs extra.
To help make backing out of a parking space safer, the AMG E-Class Cabriolet has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the 8 Series.
Both the AMG E-Class Cabriolet and the 8 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors and available lane departure warning systems.
