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 Cadillac ATS Coupe 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 ATS Coupe 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the TT. But it costs extra on the ATS Coupe.

Both the TT and the ATS Coupe 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, rearview cameras and available blind spot warning systems.

Warranty

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

Reliability

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 57 points higher than the ATS Coupe.

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 Cadillac vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 45 more problems per 100 vehicles, Cadillac is ranked 27th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Audi 21 places higher in reliability than Cadillac.

Fuel Economy and Range

On the EPA test cycle the TT RS gets better fuel mileage than the ATS Coupe AWD V6 (19 city/29 hwy vs. 18 city/27 hwy).

Transmission

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

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 ATS Coupe doesn’t offer launch control.

Brakes and Stopping

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

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 ATS Coupe doesn’t offer ceramic brake rotors.

The TT stops much shorter than the ATS Coupe:

Tires and Wheels

For better traction, the TT has larger standard tires than the ATS Coupe (245/40R18 vs. 225/40R18). The TTS/RS’ optional tires are larger than the largest tires available on the ATS Coupe (255/30R20 vs. 225/40R18).

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 ATS Coupe’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the TTS/RS offers optional 20-inch wheels. The ATS Coupe’s largest wheels are only 18-inches.

Suspension and Handling

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

The TT RS Coupe handles at 1.05 G’s, while the ATS Coupe pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The TT RS Coupe executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the ATS Coupe (23.7 seconds @ .85 average G’s vs. 25.6 seconds @ .71 average G’s).

For better maneuverability, the TT’s turning circle is 1.2 feet tighter than the ATS Coupe FE3’s (34.8 feet vs. 36 feet). The TT RS Coupe’s turning circle is 2.1 feet tighter than the ATS Coupe AWD’s (36 feet vs. 38.1 feet).

Chassis

The Audi TT may be more efficient, handle and accelerate better because it weighs about 200 to 300 pounds less than the Cadillac ATS Coupe.

The TT is 1 foot, 6.6 inches shorter than the ATS Coupe, making the TT easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The TT Coupe has a much larger trunk than the ATS Coupe (12 vs. 10.4 cubic feet).

Ergonomics

If the windows are left open on the TT the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the ATS Coupe can only operate the windows from inside the vehicle, with the ignition on.

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 ATS Coupe’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 ATS Coupe doesn’t offer heated windshield washer nozzles.

Model Availability

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

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 ATS Coupe only retains 38.92% to 41.91%.
