Over 200 people are killed each year when backed over by motor vehicles. The GTI has standard Maneuver Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The S3 doesn’t offer backup collision prevention brakes.
The GTI has a standard blind spot warning system which 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 GTI has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the S3.
The GTI’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 GTI and the S3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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 and rearview cameras.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the GTI the rating of “Top Safety Pick” for 2022, a rating granted to only 158 vehicles tested by the IIHS. The S3 has not been tested, yet.
