The Cascada has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The TT doesn’t offer a whiplash protection system.

The Cascada Premium/Sport Touring has a standard collision warning system, which detects an impending crash through forward mounted sensors and flashes a bright light and sounds a loud, distinctive tone to warn the driver to brake or maneuver immediately to avoid a collision. The TT doesn't offer a collision warning system.

The Cascada Premium/Sport Touring’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The TT doesn’t offer a lane departure warning system.

Both the Cascada and the TT 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available front parking sensors.

The Buick Cascada weighs 584 to 771 pounds more than the Audi TT. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.


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


The Buick Cascada’s engine uses a cast iron block for durability, while the TT’s 2.5 turbo 5 cyl. engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

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.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Buick Cascada uses regular unleaded gasoline (premium recommended for maximum performance). The TT requires premium, which can cost 20 to 55 cents more per gallon.

Brakes and Stopping

For better stopping power the Cascada’s standard front brake rotors are larger than those on the TT:




Front Rotors

12.6 inches

12.3 inches

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 TT 45 TSFI.

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

Suspension and Handling

For a smoother ride and more stable handling, the Cascada’s wheelbase is 7.5 inches longer than on the TT (106.1 inches vs. 98.6 inches).

For better handling and stability, the track (width between the wheels) on the Cascada is .8 inches wider in the front and 1.5 inches wider in the rear than the average track on the TT.

The Cascada’s front to rear weight distribution is more even (58.2% to 41.8%) than the TT’s (60.7% to 39.3%). This gives the Cascada more stable handling and braking.

Passenger Space

The Cascada has standard seating for 4 passengers; the TT Roadster can only carry up to 2.

Cargo Capacity

The Cascada has a much larger trunk with its top down than the TT Roadster (9.8 vs. 7.5 cubic feet).

Pressing a switch automatically lowers the Cascada’s rear seats, to make changing between passengers and cargo easier. The TT 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 TT doesn’t offer a remote starting system.

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 TT 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 TT 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.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Cascada has standard extendable sun visors. The TT doesn’t offer extendable visors.

The Cascada’s sun-visors swivel front-to-side to block glare from the side windows. The TT’s visors are fixed into the windshield header.

On extremely cold winter days, the Cascada’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The TT doesn’t offer a heated steering wheel.

The Cascada’s 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. The TT doesn’t offer dual zone air conditioning.

For greater rear passenger comfort, the Cascada has standard rear heat vents to keep rear occupants more comfortable. The TT doesn’t offer rear vents.

Economic Advantages

Insurance will cost less for the Cascada owner. The Complete Car Cost Guide estimates that insurance for the Cascada will cost $590 less than the TT over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Buick Cascada will be $5202 to $20667 less than for the Audi TT.


The Buick Cascada outsold the Audi TT by over three to one during 2018.
