Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi A7 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Cadillac CTS doesn’t offer pretensioners for the rear seat belts.

The A7 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 CTS 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 A7. But it costs extra on the CTS.

A passive infrared night vision system optional on the A7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The CTS doesn’t offer a night vision system.

Both the A7 and the CTS have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The A7’s corrosion warranty is 6 years longer than the CTS’ (12 vs. 6 years).

Reliability

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.

Engine

The A7’s 3.0 turbo V6 hybrid produces 67 more horsepower (335 vs. 268) and 74 lbs.-ft. more torque (369 vs. 295) than the CTS’ standard 2.0 turbo 4 cyl. The A7’s 3.0 turbo V6 hybrid produces 84 lbs.-ft. more torque (369 vs. 285) than the CTS’ optional 3.6 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the A7 gets better fuel mileage than the CTS 2.0 Turbo AWD (22 city/29 hwy vs. 21 city/29 hwy). The A7 gets better fuel mileage than the CTS V6 AWD (22 city/29 hwy vs. 18 city/26 hwy).

Regenerative brakes improve the A7’s fuel efficiency by converting inertia back into energy instead of wasting it. The CTS doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Audi A7 uses regular unleaded gasoline (premium recommended for maximum performance). The CTS V-Sport requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The A7 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 CTS doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the A7’s standard brake rotors are larger than those on the CTS:

Front Rotors

13.3 inches

12.6 inches

Rear Rotors

13 inches

12.4 inches

Tires and Wheels

For better ride, handling and brake cooling the A7 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the CTS. The A7 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels optional on the CTS.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A7 is 3.5 inches wider in the front and 2.4 inches wider in the rear than the average track on the CTS.

For better maneuverability, the A7’s turning circle is .3 feet tighter than the CTS V-Sport’s (36.4 feet vs. 36.7 feet). The A7’s turning circle is 2.6 feet tighter than the CTS AWD’s (36.4 feet vs. 39 feet).

Chassis

The design of the Audi A7 amounts to more than styling. The A7 has an aerodynamic coefficient of drag of .28 Cd. That is lower than the CTS (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A7 get better fuel mileage.

Passenger Space

The A7 has .3 inches more front shoulder room, 1.6 inches more rear legroom and 1.1 inches more rear shoulder room than the CTS.

Cargo Capacity

The A7 has a much larger trunk than the CTS (24.9 vs. 13.7 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, just kicking your foot under the back bumper can open the A7’s power liftgate, leaving your hands completely free. The A7’s power liftgate can also be opened or closed by pressing a button. The CTS doesn’t offer a power or hands-free opening trunk.

Ergonomics

The A7’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 CTS’ standard manually variable intermittent wipers have to be constantly adjusted.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A7 offers available headlight washers to keep headlight output high. The CTS doesn’t offer headlight washers.
