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 BMW M8 doesn’t offer pretensioners for the rear seat belts.
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. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M8 doesn’t offer height-adjustable seat belts.
The AMG E-Class Sedan 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. A system to reveal vehicles in the M8’s blind spot costs extra.
To help make backing out of a parking space safer, the AMG E-Class Sedan 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 M8.
Both the AMG E-Class Sedan and the M8 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, 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.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the AMG E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 113 vehicles tested by the IIHS. The M8 has not been tested, yet.
