For enhanced safety, the front and rear seat shoulder belts of the Audi A5 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 MINI Cooper Convertible doesn’t offer pretensioners for its rear seat belts.
The A5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cooper Convertible doesn’t offer pre-crash pretensioners.
The A5 has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Cooper Convertible doesn’t offer a whiplash protection system.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Pre Sense Front in the A5 as “Superior.” The Cooper Convertible scores only 4 points and is rated only “Advanced.”
The A5 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Cooper Convertible doesn’t offer all-wheel drive.

The A5 Premium Plus/Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The Cooper Convertible only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The A5’s optional blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Cooper Convertible doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the A5’s optional Rear Cross-Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side and Automatic Brake Activation automatically engages the brakes to help avoid a collision. The Cooper Convertible doesn’t offer a rear cross-path warning system.
Both the A5 and the Cooper Convertible have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems and rearview cameras.
The Audi A5 weighs 536 to 1053 pounds more than the MINI Cooper Convertible. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A5 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS.
