For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Altima the rating of “Top Pick” for 2018, a rating granted to only 88 vehicles tested by the IIHS. The ILX was a “Top Pick” for 2017, but no longer qualifies under the tighter 2018 guidelines.

Warranty Comparison

There are almost 4 times as many Nissan dealers as there are Acura dealers, which makes it much easier should you ever need service under the Altima’s warranty.

Reliability Comparison

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Altima’s reliability 42 points higher than the ILX.

J.D. Power and Associates rated the Altima third among midsize cars in their 2017 Initial Quality Study. The ILX isn’t in the top three in its category.

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Acura vehicles. J.D. Power ranks Nissan 10th in initial quality, above the industry average. With 10 more problems per 100 vehicles, Acura is ranked 19th, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Nissan vehicles are more reliable than Acura vehicles. J.D. Power ranks Nissan 10th in reliability, above the industry average. With 26 more problems per 100 vehicles, Acura is ranked 20th.

Engine Comparison

The Altima 3.5’s standard 3.5 DOHC V6 produces 69 more horsepower (270 vs. 201) and 71 lbs.-ft. more torque (251 vs. 180) than the ILX’s 2.4 DOHC 4 cyl.

Fuel Economy and Range Comparison

On the EPA test cycle the Altima 2.5 gets better fuel mileage than the ILX Auto (27 city/38 hwy vs. 25 city/35 hwy).

To lower fuel costs and make buying fuel easier, the Nissan Altima uses regular unleaded gasoline. The ILX requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Altima has 4.8 gallons more fuel capacity than the ILX (18 vs. 13.2 gallons), for longer range between fill-ups.

Tires and Wheels Comparison

For better traction, the Altima 2.5 SR/3.5’s tires are larger than the largest tires available on the ILX (235/45R18 vs. 225/40R18).

The Altima has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The ILX doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Altima’s wheelbase is 4.2 inches longer than on the ILX (109.3 inches vs. 105.1 inches).

For better handling and stability, the average track (width between the wheels) on the Altima is 2.8 inches wider in the front and 2 inches wider in the rear than the track on the ILX.

The Altima’s front to rear weight distribution is more even (60.1% to 39.9%) than the ILX’s (63% to 37%). This gives the Altima more stable handling and braking.

The Altima 2.5 SL handles at .85 G’s, while the ILX A-SPEC pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the Altima V6 has an electronically controlled liquid-filled front engine mount and conventional liquid-filled engine mounts (standard liquid front mount on other versions of the Altima). A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The ILX uses conventional solid rubber engine mounts.

The front grille of the Altima 2.5 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The ILX doesn’t offer active grille shutters.

Passenger Space Comparison

Because it has more passenger and cargo room, the Altima is rated a Mid-size car by the EPA, while the ILX is rated a Compact.

The Altima has 12.6 cubic feet more passenger volume than the ILX (101.9 vs. 89.3).

The Altima has 2 inches more front headroom, 2.7 inches more front legroom, 3.7 inches more front hip room, .8 inches more front shoulder room, 1.2 inches more rear headroom, 2.1 inches more rear legroom, .4 inches more rear hip room and 2.9 inches more rear shoulder room than the ILX.

Cargo Capacity Comparison

The Altima has a much larger trunk than the ILX (15.4 vs. 12.3 cubic feet).

A low lift-over trunk design makes loading and unloading the Altima easier. The Altima’s trunk lift-over height is 26.5 inches, while the ILX’s liftover is 28.7 inches.

The Altima’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.

Ergonomics Comparison

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 Altima’s available headlights were rated “Acceptable” by the IIHS, while the ILX’s headlights are rated “Marginal.”

On extremely cold winter days, the Altima’s optional (except S/SR) 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 Altima and the ILX offer rear vents. For greater rear passenger comfort, the Altima offers optional 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.

Economic Advantages Comparison

Insurance will cost less for the Altima owner. The Car Book by Jack Gillis rates the Altima with a number “1” insurance rate while the ILX is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Altima is less expensive to operate than the ILX because typical repairs cost much less on the Altima than the ILX, including $112 less for a water pump, $214 less for an alternator, $220 less for a starter, $57 less for a fuel pump, $136 less for front struts and $398 less for a power steering pump.

Recommendations Comparison

Consumer Reports® recommends the Nissan Altima, based on reliability, safety and performance.

J.D. Power and Associates rated the Altima first among midsize cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The ILX isn’t in the top three in its category.

The Nissan Altima outsold the Acura ILX by almost 22 to one during 2017.
