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 Acura ILX 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 ILX 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 ILX 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.

The A4 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ILX doesn’t offer all-wheel drive.

The A4 Prestige has a standard Top and Corner View Cameras to allow the driver to see objects all around the vehicle on a screen. The ILX only offers a rear monitor.

Both the A4 and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front-wheel drive, 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 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 its highest rating: “Top Pick Plus” for 2017, a rating granted to only 44 vehicles tested by the IIHS. The ILX is only a standard “Top Pick” for 2017.

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

J.D. Power and Associates’ 2016 Initial Quality Study of new car owners surveyed provide the statistics that show that Audi vehicles are better in initial quality than Acura vehicles. J.D. Power ranks Audi 14th in initial quality. With 12 more problems per 100 vehicles, Acura is ranked 24th.

The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.)

For better traction, the A4 has larger standard tires than the ILX (225/50R17 vs. 215/45R17). The A4’s optional tires are larger than the largest tires available on the ILX (245/40R18 vs. 225/40R18).

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 ILX A-SPEC’s 40 series tires.

For better ride, handling and brake cooling the A4 offers optional 19-inch wheels. The ILX’s largest wheels are only 18-inches.

The A4 offers an optional 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 ILX’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the A4’s wheelbase is 5.9 inches longer than on the ILX (111 inches vs. 105.1 inches).

For better handling and stability, the track (width between the wheels) on the A4 is 2.5 inches wider in the front and 1 inch wider in the rear than on the ILX.

The A4’s front to rear weight distribution is more even (56% to 44%) than the ILX’s (63% to 37%). This gives the A4 more stable handling and braking.

The A4 Prestige Quattro handles at .90 G’s, while the ILX A-SPEC pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The A4 has a larger trunk than the ILX (13 vs. 12.3 cubic feet).

The A4’s standard folding rear seats are split to accommodate bulky cargo. The ILX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

To make loading and unloading groceries and cargo easier when your hands are full, the A4’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The A4 also offers an optional power trunk, which opens and closes automatically by pressing a button. The ILX doesn’t offer a power or hands-free opening trunk.

The A4 offers an optional heads-up display that projects speed 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 ILX doesn’t offer a heads-up display.

The power windows standard on both the A4 and the ILX have locks to prevent small children from operating them. When the lock on the A4 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The ILX prevents the driver from operating the other windows just as it does the other passengers.

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 ILX’s rear power window switches have to be held the entire time to open or close them fully.

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 ILX’s 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 A4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The ILX doesn’t offer heated windshield washer nozzles.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A4’s available headlights were rated “Acceptable” by the IIHS, while the ILX’s headlights are rated “Marginal.”

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 ILX doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the A4 Prestige detect other vehicles which could be blinded and automatically switch to low beams. The ILX doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the A4 has standard cornering lights to illuminate around corners when the turn signals are activated. The ILX doesn’t offer cornering lights.

The A4 offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The ILX offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the A4 and the ILX offer available heated front seats. The A4 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the ILX.

Optional air-conditioned seats in the A4 Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The ILX doesn’t offer air-conditioned seats.

On extremely cold winter days, the A4’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The ILX doesn’t offer a heated steering wheel.

Both the A4 and the ILX offer rear vents. For greater rear passenger comfort, the A4 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The ILX doesn’t offer rear air conditioning vents, only heat vents.

According to The Car Book by Jack Gillis, the A4 is less expensive to operate than the ILX because typical repairs cost less on the A4 than the ILX, including $21 less for a timing belt/chain and $113 less for a power steering pump.
