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 Sedan its highest rating: “Top Pick Plus” for 2017, a rating granted to only 46 vehicles tested by the IIHS. The ILX is only a standard “Top Pick” for 2017.

Warranty Comparison

The Altima Sedan’s corrosion warranty is 1 year longer than the ILX’s (5 vs. 4 years).

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 Sedan’s warranty.

Reliability Comparison

J.D. Power and Associates rated the Altima Sedan second among midsize cars in their 2016 Initial Quality Study. The ILX isn’t in the top three in its category.

J.D. Power and Associates’ 2016 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 21 more problems per 100 vehicles, Acura is ranked 24th, below the industry average.

Engine Comparison

The Altima Sedan 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 Sedan 2.5 gets better fuel mileage than the ILX Auto (27 city/39 hwy vs. 25 city/35 hwy).

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

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

The Altima Sedan 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 Sedan’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 Sedan is 2.8 inches wider in the front and 2 inches wider in the rear than the track on the ILX.

The Altima Sedan 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.

For better maneuverability, the Altima Sedan 2.5/2.5 S’ turning circle is .7 feet tighter than the ILX’s (36.1 feet vs. 36.8 feet).

Chassis Comparison

To almost totally eliminate engine vibration in the passenger area, the Altima Sedan 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 Sedan). 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 Sedan 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 Sedan is rated a Mid-size car by the EPA, while the ILX is rated a Compact.

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

The Altima Sedan 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 Sedan 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 Sedan easier. The Altima Sedan’s trunk lift-over height is 26.5 inches, while the ILX’s liftover is 28.7 inches.

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

On extremely cold Winter days, the Altima Sedan’s optional (except Base/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 Sedan and the ILX offer rear vents. For greater rear passenger comfort, the Altima Sedan 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 Sedan owner. The Car Book by Jack Gillis rates the Altima Sedan with a number “5” insurance rate while the ILX is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the Altima Sedan is less expensive to operate than the ILX because typical repairs cost much less on the Altima Sedan than the ILX, including $110 less for a water pump, $219 less for a starter, $57 less for a fuel pump, $135 less for front struts and $400 less for a power steering pump.

Recommendations Comparison

J.D. Power and Associates rated the Altima Sedan second 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 Sedan outsold the Acura ILX by almost nineteen to one during the 2016 model year.
