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 Outback are reminded to check the back seat if they opened the rear door before starting out. The A5 Sportback doesn’t offer a back seat reminder.
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 A5 Sportback doesn’t offer automatic braking for stationary objects directly to the rear.
The Subaru Outback’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Audi A5 Sportback 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 A5 Sportback’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. Audi charges extra for Rear Cross-Traffic Assist on the A5 Sportback.
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 A5 Sportback doesn’t offer a driver alert monitor.
Both the Outback and the A5 Sportback have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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, rearview cameras and available around view monitors.
