For enhanced safety, the front and rear seat shoulder belts of the Subaru Outback 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 Chevrolet Trax doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Subaru Outback are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Chevrolet Trax doesn’t offer height-adjustable seat belts.
The Subaru Outback 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 Trax doesn’t offer knee airbags.
The Outback 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 Trax doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The Outback has standard Reverse Automatic Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Trax doesn’t offer backup collision prevention brakes.
The Outback has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Trax doesn’t offer all-wheel drive.
When descending a steep, off-road slope, the Outback’s standard Hill Descent Control allows you to creep down safely. The Trax doesn’t offer Hill Descent Control.
The Outback (except Premium/Limited 2.5) offers an optional 360-Degree Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Trax only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Subaru Outback’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Chevrolet Trax does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The Outback 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. A system to reveal vehicles in the Trax’s blind spot costs extra.
To help make backing out of a parking space safer, the Outback has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Chevrolet charges extra for Rear Cross Traffic Alert on the Trax.
The Outback’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 Trax doesn’t offer a driver alert monitor.
Both the Outback and the Trax have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
The Subaru Outback weighs 705 to 999 pounds more than the Chevrolet Trax. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
