The A3’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.

Both the A3 and ILX have child safety locks to prevent children from opening the rear doors. The A3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The ILX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Audi A3 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 ILX doesn’t offer knee airbags.

The A3 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 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 A3 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ILX doesn’t offer all-wheel drive.

Both the A3 and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

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 A3 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The ILX last would have qualified as only a standard “Top Safety Pick” in 2017.

Warranty

The A3’s corrosion warranty is 7 years longer than the ILX’s (12 vs. 5 years).

There are over 12 percent more Audi dealers than there are Acura dealers, which makes it easier should you ever need service under the A3’s warranty.

Reliability

The Audi A3’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’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Acura With 12 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Audi higher than Acura.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Acura vehicles. Consumer Reports ranks Audi 14 places higher in reliability than Acura.

Engine

The A3’s 2.0 turbo 4-cylinder hybrid produces 41 lbs.-ft. more torque (221 vs. 180) than the ILX’s 2.4 DOHC 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the A3 gets better mileage than the ILX:

			MPG
A3
	FWD	2.0 turbo 4-cyl. Hybrid	28 city/38 hwy
	AWD	2.0 turbo 4-cyl. Hybrid	27 city/35 hwy
ILX
	FWD	2.4 DOHC 4-cyl.	24 city/34 hwy

Regenerative brakes improve the A3’s fuel efficiency by converting inertia back into energy instead of wasting it. The ILX doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the A3’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 ILX doesn’t offer an automatic engine start/stop system.

The A3 Quattro’s standard fuel tank has 1.3 gallons more fuel capacity than the ILX (14.5 vs. 13.2 gallons).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A3 higher (7 out of 10) than the Acura ILX (3). This means the A3 produces up to 24.5 pounds less smog-producing pollutants than the ILX every 15,000 miles.

Tires and Wheels

For better traction, the A3 has larger tires than the ILX (225/45R17 vs. 215/45R17).

The A3 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 ILX; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The A3 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 better handling and stability, the track (width between the wheels) on the A3 is 1.3 inches wider in the front than on the ILX.

Chassis

The A3 is 5.3 inches shorter than the ILX, making the A3 easier to handle, maneuver and park in tight spaces.

Passenger Space

The A3 has .7 inches more rear headroom and 1.2 inches more rear legroom than the ILX.

Cargo Capacity

To allow full utilization of available cargo room, the A3’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The ILX’s useful trunk space is reduced by its intrusive beam hinge.

The A3’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, especially for short adults, the A3 has a standard power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The ILX doesn’t offer a power trunk.

Towing

The A3 has a 3500 lbs. towing capacity. The ILX has no towing capacity.

Servicing Ease

The A3 uses gas struts to support the hood for easier service access. The ILX uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

The A3’s power parking brake sets with one touch and releases with one touch or automatically. The ILX 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.

The power windows standard on both the A3 and the ILX have locks to prevent small children from operating them. When the lock on the A3 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 A3’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 A3’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.

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 A3’s headlights were rated “Good” by the IIHS, while the ILX’s headlights are rated “Poor.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A3 Prestige 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 standard on the A3 detect other vehicles which could be blinded and automatically switch to low beams. The ILX doesn’t offer automatic dimming high beams.

The A3’s optional rear and 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 ILX offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the A3 and the ILX offer rear vents. For greater rear passenger comfort, the A3 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A3 offers an optional wireless phone charging system (Qi) in the center console. The ILX doesn’t offer wireless personal charging.

The A3’s optional Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ILX doesn’t offer an automated parking system.
