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 the 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’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Cooper Convertible doesn’t offer a whiplash protection system.
The A5 has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Cooper Convertible doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
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 Prestige’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Cooper Convertible doesn’t offer a lane departure warning system.
The A5 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 digital cameras monitored by computer to alert the driver to moving 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 safer, the A5’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Cooper Convertible doesn’t offer a cross-path warning system.
The A5 has a standard Audi Connect CARE, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Cooper Convertible doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
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, daytime running lights and rearview cameras.
The Audi A5 weighs 540 to 1135 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 all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the A5 the rating of “Top Pick” for 2017, a rating granted to only 155 vehicles tested by the IIHS. The Cooper Convertible has not been tested, yet.
There are over 2 times as many Audi dealers as there are MINI dealers, which makes it much easier should you ever need service under the A5’s warranty.
The Audi A5’s engine uses a cast iron block for durability, while the Cooper Convertible’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.
The battery on the A5 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the A5’s battery 20 to 30 degrees cooler, its life is increased by years. The Cooper Convertible’s battery is in the hot engine compartment.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than MINI vehicles. Consumer Reports ranks Audi 2 places higher in reliability than MINI.
The A5’s 2.0 turbo 4 cyl. produces 114 more horsepower (248 vs. 134) and 111 lbs.-ft. more torque (273 vs. 162) than the Cooper Convertible’s standard 1.5 turbo 3 cyl. The A5’s 2.0 turbo 4 cyl. produces 59 more horsepower (248 vs. 189) and 66 lbs.-ft. more torque (273 vs. 207) than the Cooper Convertible S’ standard 2.0 turbo 4 cyl. The A5’s 2.0 turbo 4 cyl. produces 20 more horsepower (248 vs. 228) and 37 lbs.-ft. more torque (273 vs. 236) than the John Cooper Works Convertible’s standard 2.0 turbo 4 cyl.

The Audi A5 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the Cooper Convertible.
A seven-speed automatic (SMG) is standard on the Audi A5, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Cooper Convertible.
The A5 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Cooper Convertible doesn’t offer an SMG.
All wheel drive, available in the A5, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The MINI Cooper Convertible is not available with all wheel drive.
The A5 Auto’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Cooper Convertible doesn’t offer launch control.
For better stopping power the A5’s brake rotors are larger than those on the Cooper Convertible:
John Cooper Works
For better traction, the A5 has larger standard tires than the Cooper Convertible (245/40R18 vs. 175/65R15). The A5’s optional tires are larger than the largest tires available on the Cooper Convertible (255/35R19 vs. 205/40R18).
The A5’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Cooper Convertible’s standard 65 series tires. The A5’s optional tires have a lower 35 series profile than the Cooper Convertible’s optional 40 series tires.
For better ride, handling and brake cooling the A5 has standard 18-inch wheels. Smaller 15-inch wheels are standard on the Cooper Convertible. The A5’s optional 19-inch wheels are larger than the 18-inch wheels optional on the Cooper Convertible.
The A5 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Cooper Convertible; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some models of the Cooper Convertible don’t even offer run-flats.
For a smoother ride and more stable handling, the A5 Cabriolet’s wheelbase is 10.7 inches longer than on the Cooper Convertible (108.9 inches vs. 98.2 inches).
For better handling and stability, the track (width between the wheels) on the A5 is 3.8 inches wider in the front and 3 inches wider in the rear than the average track on the Cooper Convertible.
Because it has more passenger and cargo room, the EPA rates the A5 Cabriolet a Subcompact car, while the Cooper Convertible is rated a Minicompact.
The A5 Cabriolet has 5 cubic feet more passenger volume than the Cooper Convertible (81 vs. 76).
The A5 Cabriolet has a much larger trunk with its top down than the Cooper Convertible with its top down (7.2 vs. 5.7 cubic feet). The A5 Cabriolet has a much larger trunk with its top up than the Cooper Convertible with its top up (9.3 vs. 7.6 cubic feet).
A low lift-over trunk design makes loading and unloading the A5 easier. The A5’s trunk lift-over height is 28.5 inches, while the Cooper Convertible’s liftover is 30.4 inches.
Pressing a switch automatically lowers the A5’s rear seats, to make changing between passengers and cargo easier. The Cooper Convertible doesn’t offer automatic folding seats.
With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the A5 offers cargo security. The Cooper Convertible’s non-lockable remote release defeats cargo security.
To make loading groceries and cargo easier when your hands are full, just kicking your foot under the back bumper can open the A5’s available trunk, leaving your hands completely free. The Cooper Convertible doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.
The engine in the A5 is mounted longitudinally (North-South), instead of sideways, as in the Cooper Convertible. This makes it easier to service and maintain, because the accessory belts are in front.
J.D. Power and Associates surveys of service recipients show that Audi service is better than MINI. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 4% lower rating, MINI is ranked 10th.
When two different drivers share the A5, the optional memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, suspension setting and outside mirror angle. The Cooper Convertible doesn’t offer a memory system.
The A5’s standard power windows have a locking feature to keep children in the rear seat from operating them. MINI does not offer a locking feature on the Cooper Convertible’s standard power windows.

The A5 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Cooper Convertible.
For greater rear passenger comfort, the A5 has standard rear a/c vents to keep rear occupants more comfortable. The Cooper Convertible doesn’t offer rear vents.
J.D. Power and Associates rated the A5 second among compact premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Cooper Convertible isn’t in the top three in its category.
