For enhanced safety, the front and rear seat shoulder belts of the Volkswagen Golf R 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 M3 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Volkswagen Golf R 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 M3 doesn’t offer height-adjustable seat belts.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Golf R. But it costs extra on the M3.
Both the Golf R and M3 have rear cross-traffic warning, but the Golf R has Rear Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The M3’s Cross Traffic Warning doesn’t automatically brake.
Both the Golf R and the M3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Volkswagen Golf R weighs 2160 to 2310 pounds more than the BMW M3. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
