The Golf R’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 AMG C-Class Sedan doesn’t offer a whiplash protection system.
The Golf R’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG C-Class Sedan.
Both the Golf R and the AMG C-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Volkswagen Golf R weighs 1333 to 1985 pounds more than the Mercedes AMG C-Class Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
