For enhanced safety, the front and rear seat shoulder belts of the Subaru WRX 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 Volkswagen Jetta GLI doesn’t offer pretensioners for the rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the WRX are reminded to check the back seat if they opened the rear door before starting out. The Jetta GLI doesn’t offer a back seat reminder.
The Subaru WRX has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Jetta GLI doesn’t offer knee airbags.
The WRX has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Jetta GLI doesn’t offer a whiplash protection system.
The WRX has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Jetta GLI doesn’t offer all-wheel drive.
Both the WRX and the Jetta GLI have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.
