For enhanced safety, the front and rear seat shoulder belts of the Audi S5 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 ATS Coupe doesn’t offer pretensioners for the rear seat belts.

The S5’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The ATS Coupe doesn’t offer a whiplash protection system.

The S5 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 S5. But it costs extra on the ATS Coupe.

The S5 Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The ATS Coupe only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the S5 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the S5 the rating of “Top Pick” for 2017, a rating granted to only 185 vehicles tested by the IIHS. The ATS Coupe has not been tested, yet.

The S5’s 3.0 turbo V6 produces 14 more horsepower (349 vs. 335) and 84 lbs.-ft. more torque (369 vs. 285) than the ATS Coupe’s optional 3.6 DOHC V6.

On the EPA test cycle the S5 Coupe gets better fuel mileage than the ATS Coupe AWD V6 (20 city/27 hwy vs. 18 city/27 hwy).

Regenerative brakes improve the S5’s fuel efficiency by converting inertia back into energy instead of wasting it. The ATS Coupe doesn’t offer a regenerative braking system.

For better traction, the S5 has larger standard tires than the ATS Coupe (245/40R18 vs. 225/40R18). The S5’s optional tires are larger than the largest tires available on the ATS Coupe (265/30R20 vs. 225/40R18).

The S5’s 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 S5 offers optional 20-inch wheels. The ATS Coupe’s largest wheels are only 18-inches.

The S5 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 ATS Coupe; it requires you to depend on its 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.

For better handling and stability, the track (width between the wheels) on the S5 is 2.2 inches wider in the front than on the ATS Coupe.

The S5 Coupe has a larger trunk than the ATS Coupe (10.9 vs. 10.4 cubic feet).

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the S5 offers cargo security. The ATS Coupe’s non-lockable folding seat defeats cargo security.

To make loading groceries and cargo easier when your hands are full, the S5’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The ATS Coupe doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The S5’s power parking brake sets with one touch and releases with one touch or automatically. The ATS Coupe has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

If the windows are left open on the S5 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 lower the windows from a distance using the keyless remote. The driver of the ATS Coupe can only operate the windows from inside the vehicle, with the ignition on.

The S5’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 S5 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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S5 Prestige has standard headlight washers to keep headlight output high. The ATS Coupe doesn’t offer headlight washers.

Optional air-conditioned seats in the S5 Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The ATS Coupe doesn’t offer air-conditioned seats.

The S5 has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the ATS Coupe.

The S5 Prestige’s Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ATS Coupe doesn’t offer an automated parking system.

The S5 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S5 will retain 41.89% to 46.48% of its original price after five years, while the ATS Coupe only retains 37.25% to 39.01%.
