Safety

Using vehicle speed sensors, smart airbags in the ILX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The ILX’s side airbags will shut off if a child is leaning against the door. The A4’s airbags don’t have smart features and will always deploy full force.

Both the ILX and the A4 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura ILX is safer than the Audi A4:

Warranty

Acura’s powertrain warranty covers the ILX 2 years and 20,000 miles longer than Audi covers the A4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A4 ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates rated the ILX first among small premium cars in their 2018 Initial Quality Study. The A4 isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Acura 20th in initial quality. With 6 more problems per 100 vehicles, Audi is ranked 25th.

Engine

The ILX’s 2.4 DOHC 4 cyl. produces 13 more horsepower (201 vs. 188) than the A4 40 TFSI’s standard 2.0 turbo 4 cyl.

Transmission

An eight-speed automatic (SMG) is standard on the Acura ILX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A4.

Tires and Wheels

The ILX’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the A4’s standard 50 series tires.

Suspension and Handling

For better maneuverability, the ILX’s turning circle is 1.3 feet tighter than the A4’s (36.8 feet vs. 38.1 feet).

Chassis

The Acura ILX may be more efficient, handle and accelerate better because it weighs about 350 to 500 pounds less than the Audi A4.

The ILX is 3.9 inches shorter than the A4, making the ILX easier to handle, maneuver and park in tight spaces.

The ILX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The A4 doesn’t offer active noise cancellation.

Ergonomics

The ILX offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A4 doesn’t offer a remote starting system.

If the windows are left open on the ILX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the A4 can’t use the remote to operate the windows.

When the ILX is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The A4’s mirrors don’t automatically adjust for backing.

Economic Advantages

Insurance will cost less for the ILX owner. The Complete Car Cost Guide estimates that insurance for the ILX will cost $375 to $4875 less than the A4 over a five-year period.

According to The Car Book by Jack Gillis, the ILX is less expensive to operate than the A4 because it costs $396 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the ILX than the A4, including $351 less for a water pump, $311 less for a muffler, $52 less for front brake pads, $216 less for a starter, $54 less for a fuel pump, $472 less for front struts and $278 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura ILX will be $7629 to $15409 less than for the Audi A4.
