For enhanced safety, the front and rear seat shoulder belts of the Subaru Impreza 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 Nissan Versa doesn’t offer pretensioners for its rear seat belts.
The Impreza 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 Versa doesn’t offer a whiplash protection system.
The Impreza has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Versa doesn’t offer all-wheel drive.
Both the Impreza and the Versa have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.
The Subaru Impreza weighs 450 to 724 pounds more than the Nissan Versa. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Subaru Impreza is safer than the Nissan Versa:
