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, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

The Audi A6 weighs 441 to 606 pounds more than the Cadillac CT5. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The CT5 has not been tested, yet.

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 stopping power the A6’s standard brake rotors are larger than those on the CT5:

A6

CT5

Front Rotors

13.3 inches

12.6 inches

Rear Rotors

13 inches

12.4 inches

The A6’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the CT5 are solid, not vented.

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.

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.

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).

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.
