Both the Discovery Sport and Outback have child safety locks to prevent children from opening the rear doors. The Discovery Sport has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Outback’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Discovery Sport has a standard 3D Surround Camera to allow the driver to see objects all around the vehicle on a screen. The Outback 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 Discovery Sport 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 Outback’s blind spot costs extra.
To help make backing out of a parking space safer, the Discovery Sport has standard Rear Traffic Monitor and Rear Traffic Braking automatically engages the brakes to help avoid a collision. Subaru charges extra for Rear Cross Traffic Alert on the Outback and its not available on the Base and the Outback’s Rear Cross Traffic Alert does not include automatic braking.
Compared to metal, the Discovery Sport’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Outback has a metal gas tank.
Both the Discovery Sport and the Outback have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
