Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi TT have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The MINI Cooper Convertible doesn’t offer pretensioners for the rear seat belts.

The TT has a standard Secondary Collision Brake Assist, which automatically applies 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 TT 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 TT’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.

The TT offers an optional Audi Connect CARE, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, 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 TT 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

Warranty

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 TT’s warranty.

Reliability

The battery on the TT is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the TT’s battery 20 to 30 degrees cooler, its life is increased by years. The Cooper Convertible’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than MINI vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 12 more problems per 100 vehicles, MINI is ranked 17th.

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.

Fuel Economy and Range

The TT has 2.9 gallons more fuel capacity than the Cooper Convertible (14.5 vs. 11.6 gallons), for longer range between fill-ups.

Transmission and Drivetrain

The Audi TT 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 TT, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Cooper Convertible.

The TT 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 TT, 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 TT RS’ 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.

Brakes and Stopping

For better stopping power the TT’s brake rotors are larger than those on the Cooper Convertible:

The TTS Coupe’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Cooper Convertible are solid, not vented.

The TT RS offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Cooper Convertible doesn’t offer ceramic brake rotors.

The TT stops much shorter than the Cooper Convertible:

Car and Driver

Tires and Wheels

For better traction, the TT has larger standard tires than the Cooper Convertible (245/40R18 vs. 175/65R15). The TTS/RS’ optional tires are larger than the largest tires available on the Cooper Convertible (255/30R20 vs. 205/40R18).

The TT 45 TSFI’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 TTS/RS’ optional tires have a lower 30 series profile than the Cooper Convertible’s optional 40 series tires.

For better ride, handling and brake cooling the TT 45 TSFI has standard 18-inch wheels. Smaller 15-inch wheels are standard on the Cooper Convertible. The TTS/RS’ optional 20-inch wheels are larger than the 18-inch wheels optional on the Cooper Convertible.

Suspension and Handling

For better handling and stability, the average track (width between the wheels) on the TT is 3.1 inches wider in the front and 2.3 inches wider in the rear than the average track on the Cooper Convertible.

For better maneuverability, the TT’s turning circle is .6 feet tighter than the Cooper Convertible’s (34.8 feet vs. 35.4 feet).

Cargo Capacity

The TT Roadster has a much larger trunk than the Cooper Convertible with its top down (7.5 vs. 5.7 cubic feet).

Servicing Ease

The engine in the TT 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 third in service department satisfaction. With a 22% lower rating, MINI is ranked 10th.

Recommendations
