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 Cascada 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 Cascada 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 Cascada doesn’t offer a system to reveal objects in the driver’s blind spots.

Both the TT and the Cascada 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 and rearview cameras.


The TT’s corrosion warranty is 6 years longer than the Cascada’s (12 vs. 6 years).


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 Cascada’s battery is in the hot engine compartment.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the TT’s reliability 14 points higher than the Cascada.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Buick vehicles. Consumer Reports ranks Audi 12 places higher in reliability than Buick.


The TT 45 TFSI’s standard 2.0 turbo 4 cyl. produces 28 more horsepower (228 vs. 200) and 37 lbs.-ft. more torque (258 vs. 221) than the Cascada’s 1.6 turbo 4 cyl. The TTS’ standard 2.0 turbo 4 cyl. produces 88 more horsepower (288 vs. 200) and 59 lbs.-ft. more torque (280 vs. 221) than the Cascada’s 1.6 turbo 4 cyl. The TT RS Coupe’s standard 2.5 turbo 5 cyl. produces 200 more horsepower (400 vs. 200) and 133 lbs.-ft. more torque (354 vs. 221) than the Cascada’s 1.6 turbo 4 cyl.

Transmission and Drivetrain

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 Cascada.

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 Cascada doesn’t offer an SMG or a conventional manual transmission.

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 Buick Cascada 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 Cascada doesn’t offer launch control.

Brakes and Stopping

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





Front Rotors

13.3 inches

14.6 inches

12.6 inches

Rear Rotors

12.2 inches

12.2 inches

11.5 inches

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 Cascada 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 Cascada doesn’t offer ceramic brake rotors.

The TT stops much shorter than the Cascada:

Tires and Wheels

For better traction, the TTS/RS’ optional tires are larger than the largest tires available on the Cascada (255/30R20 vs. 245/40R20).

The TTS/RS’ optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the Cascada’s 40 series tires.

Suspension and Handling

For superior ride and handling, the Audi TT has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Buick Cascada has a rear torsion beam axle, with a semi-independent rear suspension.

The TT has standard front and rear stabilizer bars, which help keep the TT flat and controlled during cornering. The Cascada’s suspension doesn’t offer a rear stabilizer bar.

The TT offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Cascada’s suspension doesn’t offer adjustable shock absorbers.

For better maneuverability, the TT’s turning circle is 3.9 feet tighter than the Cascada’s (34.8 feet vs. 38.7 feet). The TT RS Coupe’s turning circle is 2.7 feet tighter than the Cascada’s (36 feet vs. 38.7 feet).


The Audi TT may be more efficient, handle and accelerate better because it weighs about 600 to 750 pounds less than the Buick Cascada.

The TT is 1 foot, 7.9 inches shorter than the Cascada, making the TT easier to handle, maneuver and park in tight spaces.

Cargo Capacity

A standard locking glovebox keeps your small valuables safer in the TT. The Cascada doesn’t offer locking storage for small valuables.

Servicing Ease

The TT uses gas struts to support the hood for easier service access. The Cascada uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the TT is mounted longitudinally (North-South), instead of sideways, as in the Cascada. 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 Buick. J.D. Power ranks Audi third in service department satisfaction. With a 21% lower rating, Buick is ranked 9th.


Audi Advanced Key standard on the TT allows you to unlock the driver’s door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before getting in the vehicle in bad weather or making a hurried start to your trip. The Buick Cascada doesn’t offer an advanced key system.

The TT’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Cascada’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the TT to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cascada doesn’t offer heated windshield washer nozzles.

The TT has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Cascada has an automatic rear view mirror, but its side mirrors don’t dim.

A built-in pollen filter removes pollen, exhaust fumes and other pollutants from the TT’s passenger compartment. This helps prevent lung and/or sinus irritation, which can trigger allergies or asthma. The Cascada doesn’t offer a filtration system.

Model Availability

The Audi TT comes in coupe and convertible bodystyles; the Buick Cascada isn’t available as a coupe.

Economic Advantages

The TT will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the TT will retain 45.93% to 49.67% of its original price after five years, while the Cascada only retains 35.55% to 35.99%.


Consumer Reports® recommends the Audi TT, based on reliability, safety and performance. The Buick Cascada isn't recommended.
