Both the Cascada and the A5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available collision warning systems, lane departure warning systems and front parking sensors.


Buick’s powertrain warranty covers the Cascada 2 years and 20,000 miles longer than Audi covers the A5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A5 ends after only 4 years or 50,000 miles.

There are almost 7 times as many Buick dealers as there are Audi dealers, which makes it much easier should you ever need service under the Cascada’s warranty.


To reliably power the ignition and other systems and to recharge the battery, the Cascada has a 140-amp alternator. The A5’s standard 110-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Cascada has a standard 801-amp battery. The A5’s 420-amp battery isn’t as powerful.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Buick 16th in initial quality. With 10 more problems per 100 vehicles, Audi is ranked 25th.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Audi vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 25 more problems per 100 vehicles, Audi is ranked 13th.

Tires and Wheels

For better ride, handling and brake cooling the Cascada has standard 20-inch wheels. Smaller 18-inch wheels are standard on the A5. The A5’s largest wheels are only 19-inches.

The Cascada 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 A5; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Cargo Capacity

The Cascada has a much larger trunk with its top down than the A5 Cabriolet with its top down (9.8 vs. 7.2 cubic feet). The Cascada has a much larger trunk with its top up than the A5 Cabriolet with its top up (13.4 vs. 9.3 cubic feet).

Pressing a switch automatically lowers the Cascada’s rear seats, to make changing between passengers and cargo easier. The A5 doesn’t offer automatic folding seats.


The Cascada has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A5 doesn’t offer a remote starting system.

On a hot day the Cascada’s driver can lower all the windows from a distance using the keyless remote. The driver of the A5 can’t use the remote to operate the windows.

In case of a sudden change of weather, the Cascada has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. The A5 doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

To help drivers avoid possible obstacles, the Cascada has standard cornering lights to illuminate around corners when the turn signals are activated. The A5 doesn’t offer cornering lights. The Cascada also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The Cascada has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the A5.

Economic Advantages

Insurance will cost less for the Cascada owner. The Complete Car Cost Guide estimates that insurance for the Cascada will cost $610 to $4485 less than the A5 over a five-year period.
