For enhanced safety, the front and rear seat shoulder belts of the Audi A6 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Cadillac CT5 doesn’t offer pretensioners for the rear seat belts.

Both the A6 and CT5 have child safety locks to prevent children from opening the rear doors. The A6 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The CT5’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The A6 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 CT5 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 A6. But it costs extra on the CT5.

A passive infrared night vision system optional on the A6 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 CT5 doesn’t offer a night vision system.

Both the A6 and the CT5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 its highest rating: “Top Pick Plus” for 2020, a rating granted to only 32 vehicles tested by the IIHS. The CT5 has not been tested, yet.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Audi vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Audi 16 places higher in reliability than Cadillac.

Regenerative brakes improve the A6’s fuel efficiency by converting inertia back into energy instead of wasting it. The CT5 doesn’t offer a regenerative braking system.

The A6 has 2.3 gallons more fuel capacity than the CT5 (19.3 vs. 17 gallons), for longer range between fill-ups.

The A6 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 CT5 doesn’t offer an SMG or a conventional manual transmission.

For better traction, the A6’s optional tires are larger than the largest tires available on the CT5 (255/40R20 vs. 245/45R18).

The A6 Prestige’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the CT5’s optional 40 series tires.

For better ride, handling and brake cooling the A6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the CT5. The A6 Prestige’s optional 21-inch wheels are larger than the 19-inch wheels optional on the CT5.

The A6 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 CT5; it requires you to depend on its optional run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The A6 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 CT5’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the A6 is 1.4 inches wider in the front than on the CT5.

The A6 Prestige handles at .93 G’s, while the CT5 Sport pulls only .88 G’s of cornering force in a Motor Trend skidpad test.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the CT5 Sport (24.9 seconds @ .75 average G’s vs. 26.2 seconds @ .68 average G’s).

For better maneuverability, the A6’s turning circle is 2.6 feet tighter than the CT5’s (36.4 feet vs. 39 feet). The A6’s turning circle is 4.3 feet tighter than the CT5 AWD’s (36.4 feet vs. 40.7 feet).

The A6 has a much larger trunk than the CT5 (13.7 vs. 11.9 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the A6 offers cargo security. The CT5’s non-lockable folding seat defeats cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the A6 (except Premium) offers an optional power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The CT5 doesn’t offer a power trunk, so its trunk has to be closed manually.

The A6’s standard towing capacity is much higher than the CT5’s (3500 vs. 1000 pounds).

Unlike the driver-only memory system in the CT5 Premium Luxury/Sport, the A6 offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A6 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The CT5 doesn’t offer headlight washers.

The CT5 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The A6’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

A power rear sunshade and manual rear side window sunshades are optional in the A6 Prestige to help block heat and glare for the rear passengers. The CT5 doesn’t offer a rear or rear side window sunshades.

The A6 has standard heated front seats. Heated front seats cost extra on the CT5. The A6 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT5.
