Compare the2022 Acura ILX VS 2022 Subaru Legacy

Compared to metal, the ILX’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Legacy has a metal gas tank.

Both the ILX and the Legacy have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Acura ILX is safer than the Subaru Legacy:

	ILX	Legacy
	Front Seat
STARS	5 Stars	5 Stars
Abdominal Force	143 G’s	216 G’s
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	14 inches	14 inches

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The ILX comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Legacy’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Acura’s powertrain warranty covers the ILX 1 year and 10,000 miles longer than Subaru covers the Legacy. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Legacy ends after only 5 years or 60,000 miles.

J.D. Power and Associates rated the ILX second among small premium cars in their 2020 Initial Quality Study. The Legacy isn’t in the top three in its category.

J.D. Power and Associates’ 2020 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Acura 23rd in initial quality. With 2 more problems per 100 vehicles, Subaru is ranked 27th.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Acura vehicles are more reliable than Subaru vehicles. J.D. Power ranks Acura 10th in reliability, above the industry average. With 17 more problems per 100 vehicles, Subaru is ranked 17th.

The ILX’s 2.4 DOHC 4-cylinder produces 19 more horsepower (201 vs. 182) and 4 lbs.-ft. more torque (180 vs. 176) than the Legacy 2.5i’s standard 2.5 DOHC 4-cylinder.

As tested in Car and Driver the Acura ILX is faster than the Legacy 2.5i 2.5 DOHC 4-cylinder:

	ILX	Legacy
Zero to 60 MPH	6.6 sec	8 sec
Zero to 100 MPH	17.2 sec	22 sec
5 to 60 MPH Rolling Start	7 sec	8.6 sec
Quarter Mile	15.2 sec	16.2 sec
Speed in 1/4 Mile	94 MPH	88 MPH
Top Speed	133 MPH	130 MPH

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 Legacy Base/Premium’s standard 55 series tires. The ILX A-SPEC’s tires have a lower 40 series profile than the Legacy Sport/Limited/Touring’s 50 series tires.

The ILX has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Legacy doesn’t offer variable-assist power steering.

The Acura ILX may be more efficient, handle and accelerate better because it weighs about 400 to 650 pounds less than the Subaru Legacy.

The ILX is 8.4 inches shorter than the Legacy, 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 Legacy 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 Legacy’s non-lockable folding seat and non-lockable remote release defeat cargo security.

J.D. Power and Associates surveys of service recipients show that Acura service is better than Subaru. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 24% lower rating, Subaru is ranked 22nd.

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

The ILX’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Legacy’s manually variable intermittent wipers have to be constantly adjusted.

The ILX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Legacy Premium/Sport/Limited/Touring.

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 Legacy Premium/Sport/Limited/Touring.

According to The Car Book by Jack Gillis, the ILX is less expensive to operate than the Legacy because it costs $618 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the ILX than the Legacy, including $12 less for a water pump and $182 less for a timing belt/chain.
