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 Audi S3 doesn’t offer pretensioners for its rear seat belts.
Over 200 people are killed each year when backed over by motor vehicles. The Golf R has standard Maneuver Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The S3 doesn’t offer automatic braking for stationary objects directly to the rear.
The Golf R has a standard blind spot warning system that 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 S3’s blind spot costs extra.
To help make backing out of a parking space safer, the Golf R has standard Rear Traffic Alert and automatically engage the brakes. Audi charges extra for Rear Cross-Traffic Assist on the S3.
The Golf R’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The S3 doesn’t offer a driver alert monitor.
Both the Golf R and the S3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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, lane departure warning systems and rearview cameras.
