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 S4 doesn’t offer backup collision prevention brakes.
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 S4’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-path warning on the S4.
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 S4 doesn’t offer a driver alert monitor.
Both the Golf R and the S4 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, plastic fuel tanks, 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.
