Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi A4 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 Kia Stinger doesn’t offer pretensioners for the rear seat belts.

The A4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Stinger doesn’t offer pre-crash pretensioners.

The A4 has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Stinger 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.

When descending a steep, off-road slope, the A4’s standard Hill Descent Control allows you to creep down safely. The Stinger doesn’t offer Hill Descent Control.

Both the A4 and the Stinger have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the A4 the rating of “Top Pick” for 2018, a rating granted to only 85 vehicles tested by the IIHS. The Stinger has not been tested, yet.

Warranty

The A4’s corrosion warranty is 7 years and unlimited miles longer than the Stinger’s (12/unlimited vs. 5/100,000).

Reliability

The Audi A4’s engines use a cast iron block for durability, while the Stinger’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

Engine

The A4 45 TFSI’s standard 2.0 turbo 4 cyl. produces 13 lbs.-ft. more torque (273 vs. 260) than the Stinger 2.0L’s standard 2.0 turbo 4 cyl.

As tested in Motor Trend the A4 45 TFSI is faster than the Stinger GT:

Transmission

The A4 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 Stinger doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The A4’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 Stinger 2.0L are solid, not vented.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The A4 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Stinger doesn’t offer a brake assist feature.

The A4 stops much shorter than the Stinger:

Tires and Wheels

For better traction, the A4’s optional tires are larger than the largest tires available on the Stinger (245/40R18 vs. 225/40R19).

The A4’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 Stinger GT’s 40 series front tires.

Suspension and Handling

The A4 Premium Plus Quattro handles at .92 G’s, while the Stinger GT pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The A4 Premium Plus Quattro executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Stinger Premium (25.3 seconds @ .74 average G’s vs. 26.8 seconds @ .67 average G’s).

Chassis

The A4 is 4.1 inches shorter than the Stinger, making the A4 easier to handle, maneuver and park in tight spaces.

The design of the Audi A4 amounts to more than styling. The A4 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the Stinger (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A4 get better fuel mileage.

As tested by Car and Driver, the interior of the A4 Prestige Quattro is quieter than the Stinger GT2:

Passenger Space

The A4 has .6 inches more front headroom and .4 inches more rear headroom than the Stinger.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the A4 offers cargo security. The Stinger’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Kia. J.D. Power ranks Audi third in service department satisfaction. With a 45% lower rating, Kia is ranked 18th.

Ergonomics

The A4’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Stinger’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the A4 the driver can close them all at the outside door handle. The driver of the Stinger can only operate the windows from inside the vehicle, with the ignition on.

The A4’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 Stinger’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Stinger 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 A4 has standard headlight washers to keep headlight output high. The Stinger doesn’t offer headlight washers.

Economic Advantages

The A4 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the A4 will retain 46.36% to 48.7% of its original price after five years, while the Stinger only retains 40% to 43.12%.

Recommendations

Consumer Reports® chose the Audi A4 as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

J.D. Power and Associates rated the A4 first among compact premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Stinger isn’t in the top three.

The Audi A4/S4 outsold the Kia Stinger by almost three to one during the 2018 model year.
