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 CT4-V are reminded to check the back seat if they opened the rear door before starting out. The S5 Sportback doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The CT4-V Auto has standard Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The S5 Sportback doesn’t offer backup collision prevention brakes.
The CT4-V has a standard blind spot warning system which 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 S5 Sportback’s blind spot costs extra.
To help make backing out of a parking space safer, the CT4-V has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the S5 Sportback.
Both the CT4-V and the S5 Sportback have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.
