Compare the2022 Acura ILX VS 2022 Hyundai Sonata

The ILX has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Sonata doesn’t offer a whiplash protection system.

Both the ILX and the Sonata 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, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.

J.D. Power and Associates rated the ILX second among small premium cars in their 2021 Initial Quality Study. The Sonata isn’t in the top three in its category.

The ILX’s 2.4 DOHC 4-cylinder produces 21 more horsepower (201 vs. 180) than the Sonata SEL Plus/Limited’s standard 1.6 turbo 4-cylinder. The ILX’s 2.4 DOHC 4-cylinder produces 10 more horsepower (201 vs. 191) than the Sonata’s standard 2.5 DOHC 4-cylinder.

As tested in Car and Driver the Acura ILX is faster than the Sonata SEL Plus/Limited 1.6 turbo 4-cylinder:

	ILX	Sonata
Zero to 60 MPH	6.6 sec	7.3 sec
Zero to 100 MPH	17.2 sec	20 sec
5 to 60 MPH Rolling Start	7 sec	7.8 sec
Quarter Mile	15.2 sec	15.6 sec
Speed in 1/4 Mile	94 MPH	90 MPH

For better stopping power the ILX’s standard front brake rotors are larger than those on the Sonata:

	ILX	Sonata
Front Rotors	12.3 inches	12 inches

For better traction, the ILX has larger standard tires than the Sonata (215/45R17 vs. 205/65R16).

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 Sonata SE’s standard 65 series tires.

For better ride, handling and brake cooling the ILX has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE.

The ILX is 10.7 inches shorter than the Sonata, 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 Sonata doesn’t offer active noise cancellation.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the ILX offers cargo security. The Sonata’s non-lockable remote release defeats cargo security.

J.D. Power and Associates surveys of service recipients show that Acura service is better than Hyundai. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 27% lower rating, Hyundai is ranked 24th.

The ILX’s front power windows 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 Sonata’s standard passenger windows don’t open or close automatically. The Sonata SEL/SEL Plus/Limited/N Line’s rear windows don’t close automatically.

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 Sonata can only operate the windows from inside the vehicle, with the ignition on.

The ILX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Sonata SEL/SEL Plus/Limited/N Line.

The ILX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Sonata SEL/SEL Plus/Limited/N Line.

According to The Car Book by Jack Gillis, the ILX is less expensive to operate than the Sonata because it costs $318 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the ILX than the Sonata, including $304 less for a muffler and $275 less for a timing belt/chain.
