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 Dodge Challenger doesn’t offer pretensioners for its rear seat belts.

The S5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Challenger doesn’t offer pre-crash pretensioners.

The Audi S5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Challenger doesn’t offer knee airbags.

The S5 has standard Pre Sense Front, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Challenger offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

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 Challenger 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 Challenger.

The S5’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Challenger doesn’t offer a lane departure warning system.

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

Both the S5 and the Challenger have standard driver and passenger frontal airbags, front side-impact 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 blind spot warning systems and rear cross-path warning.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Audi S5 Coupe is safer than the Challenger:

	S5	Challenger
Overall Evaluation	GOOD	MARGINAL
Restraints	GOOD	GOOD
Head Neck Evaluation	GOOD	GOOD
Peak Head Forces	0 G’s	0 G’s
Steering Column Movement Rearward	0 cm	8 cm
Chest Evaluation	GOOD	GOOD
Hip & Thigh Evaluation	GOOD	GOOD
Hip & Thigh Injury Risk R/L	0%/0%	0%/0%
Lower Leg Evaluation	MARGINAL	POOR
Tibia index R/L	.74/1.02	1.46/1.01

The Insurance Institute for Highway Safety (IIHS) performs roof strength tests. In that test the S5 earned the top rating of “Good” because its roof supported over four times the S5’s weight before being crushed five inches. The Challenger was rated lower at “Acceptable.”

The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the S5 is safer than the Challenger:

	S5	Challenger
Overall Evaluation	GOOD	ACCEPTABLE
Head Restraint Design	GOOD	GOOD
Distance from Back of Head	22 mm	61 mm
Distance Below Top of Head	-7 mm	28 mm
Dynamic Test Rating	GOOD	ACCEPTABLE
Seat Design	Pass	Fail
Neck Force Rating	Low	Low
Max Neck Shearing Force	0	83
Max Neck Tension	222	456

(Lower numerical results are better in all tests.)

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 S5 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 109 vehicles tested by the IIHS. The Challenger is not even a standard “Top Safety Pick.”

Warranty

The S5 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Challenger’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The S5’s corrosion warranty is 7 years longer than the Challenger’s (12 vs. 5 years).

Reliability

For smoother operation, better efficiency and fewer moving parts, the S5 has an overhead cam design, rather than the old pushrod design of some of the engines in the Challenger.

Engine

The S5’s 3.0 turbo V6 produces 46 more horsepower (349 vs. 303) and 101 lbs.-ft. more torque (369 vs. 268) than the Challenger’s standard 3.6 DOHC V6.

As tested in Car and Driver the Audi S5 is faster than the Dodge Challenger V6 (automatics tested):

	S5	Challenger
Zero to 60 MPH	4.3 sec	6.3 sec
Zero to 100 MPH	10.9 sec	16.3 sec
5 to 60 MPH Rolling Start	5.6 sec	6.7 sec
Quarter Mile	12.9 sec	14.8 sec
Speed in 1/4 Mile	107 MPH	95 MPH
Top Speed	155 MPH	131 MPH

Fuel Economy and Range

On the EPA test cycle the S5 Coupe gets better mileage than the Challenger:

			MPG
S5 Coupe
AWD	Auto	3.0 turbo V6	21 city/30 hwy
Challenger
RWD	Manual	6.4 OHV V8	14 city/23 hwy
		5.7 OHV V8	15 city/23 hwy

AWD	Auto	3.6 DOHC V6	18 city/27 hwy

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

In heavy traffic or at stoplights the S5’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Challenger doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Audi S5 uses regular unleaded gasoline (premium recommended for maximum performance). The Challenger R/T manual requires premium, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi S5 higher (5 out of 10) than the Dodge Challenger (1 to 3). This means the S5 produces up to 39 pounds less smog-producing pollutants than the Challenger every 15,000 miles.

Brakes and Stopping

For better stopping power the S5’s standard brake rotors are larger than those on the Challenger:

	S5	Challenger
Front Rotors	13.8 inches	12.6 inches
Rear Rotors	13 inches	12.6 inches

The S5’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Challenger SXT are solid, not vented.

The S5 stops much shorter than the Challenger:

	S5	Challenger
70 to 0 MPH	150 feet	176 feet	Car and Driver

Tires and Wheels

For better traction, the S5 has larger standard tires than the Challenger (255/35R19 vs. 235/55R18).

The S5’s standard tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Challenger SXT’s standard 55 series tires. The S5’s optional tires have a lower 30 series profile than the Challenger Widebody’s 35 series tires.

For better ride, handling and brake cooling the S5 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Challenger SXT.

Chassis

The S5 is 1 foot shorter than the Challenger, making the S5 easier to handle, maneuver and park in tight spaces.

The design of the Audi S5 amounts to more than styling. The S5 offers aerodynamic coefficients of drag from .31 to .32 Cd (depending on bodystyle and options). That is lower than the Challenger (.337 to .398). A more efficient exterior helps the S5 go faster and keeps the interior quieter. It also helps the S5 get better fuel mileage.

For excellent aerodynamics, the S5 has standard flush composite headlights. The Challenger has recessed headlights that spoil its aerodynamic shape and create extra drag.

As tested by Car and Driver, the interior of the S5 Prestige Coupe is quieter than the Challenger SRT Hellcat:

	S5	Challenger
At idle	39 dB	59 dB
Full-Throttle	75 dB	87 dB
70 MPH Cruising	65 dB	76 dB

Cargo Capacity

Pulling a handle automatically lowers the S5’s rear seats, to make changing between passengers and cargo easier. The Challenger doesn’t offer automatic folding seats.

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the S5 offers cargo security. The Challenger’s non-lockable folding seat and non-lockable remote release defeat 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 Challenger doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Dodge. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 25% lower rating, Dodge is ranked 21st.

Ergonomics

The S5 Prestige has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Challenger doesn’t offer a heads-up display.

The S5’s power parking brake sets with one touch and releases with one touch or automatically. The Challenger’s parking brake has to be released manually.

The S5’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Challenger’s power windows’ switches have to be held the entire time to close them fully.

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 Challenger can only close the windows from inside the vehicle, with the ignition on.

The S5 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The Challenger doesn’t offer a locking fuel door.

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 Challenger’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 Challenger doesn’t offer heated windshield washer nozzles.

The S5’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Challenger’s standard projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen. The S5’s LED headlights produce a white, bright light using less electricity than the Challenger’s optional xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

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 has standard headlight washers to keep headlight output high. The Challenger doesn’t offer headlight washers.

To help drivers see further while navigating curves, the S5 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Challenger doesn’t offer cornering lights.

When the S5 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Challenger’s mirror doesn’t automatically adjust for backing.

The S5’s standard rear view mirror and optional side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Challenger has an automatic rear view mirror, but its side mirrors don’t dim.

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 Challenger.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi S5 Premium Plus/Prestige has a standard wireless phone charging system (Qi) in the center console. The Challenger doesn’t offer wireless personal charging.

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 Challenger doesn’t offer an automated parking system.

Model Availability

The Audi S5 comes in coupe, convertible and four door hatchback bodystyles; the Dodge Challenger isn’t available as a convertible or four door.
