For enhanced safety, the front and middle seat shoulder belts of the Mercedes E-Class Wagon 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 6 Series Gran Turismo doesn’t offer pretensioners for the middle seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes E-Class Wagon 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 6 Series Gran Turismo doesn’t offer height-adjustable seat belts.

Both the E-Class Wagon and the 6 Series Gran Turismo 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, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
