The IS’ optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Integra doesn’t offer pre-crash pretensioners.

The IS has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Integra doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The IS offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Integra doesn’t offer all-wheel drive.

The IS offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Integra only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the IS and Integra have rear cross-traffic warning, but the IS offers optional Rear Cross-Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Integra’s Rear Cross Traffic Monitor doesn’t automatically brake.

Both the IS and the Integra have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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, blind spot warning systems, rearview cameras and rear cross-path warning.

The Lexus IS weighs 496 to 818 pounds more than the Acura Integra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the IS its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 127 vehicles tested by the IIHS. The Integra is only a standard “Top Safety Pick” for 2019.

Warranty

The IS’ corrosion warranty is 1 year longer than the Integra’s (6 vs. 5 years).

Reliability

J.D. Power and Associates rated the IS first among compact premium cars in their 2023 Initial Quality Study. The Integra isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Acura vehicles. J.D. Power ranks Lexus above average in initial quality. With 36 more problems per 100 vehicles, Acura is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Acura vehicles. J.D. Power ranks Lexus above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, Acura is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lexus vehicles are more reliable than Acura vehicles. Consumer Reports ranks Lexus second in overall reliability. Acura is ranked 8th.

Engine

The IS has more powerful engines than the Integra:

	Horsepower	Torque
IS 300 2.0 turbo 4-cylinder	241 HP	258 lbs.-ft.
IS 300 AWD 3.5 DOHC V6	260 HP	236 lbs.-ft.
IS 350 F Sport 3.5 DOHC V6	311 HP	280 lbs.-ft.
IS 500 5.0 DOHC V8	472 HP	395 lbs.-ft.
Integra 1.5 turbo 4-cylinder	200 HP	192 lbs.-ft.
Integra Type S 2.0 turbo 4-cylinder	320 HP	310 lbs.-ft.

As tested in Motor Trend the IS 300 AWD 3.5 DOHC V6 is faster than the Acura Integra 1.5 turbo 4-cylinder (automatics tested):

	IS	Integra
Zero to 60 MPH	5.7 sec	7.6 sec
Quarter Mile	14.3 sec	15.9 sec
Speed in 1/4 Mile	97.6 MPH	92.9 MPH

As tested in Motor Trend the IS 500 5.0 DOHC V8 is faster than the Acura Integra 1.5 (automatics tested):

	IS	Integra
Zero to 60 MPH	4.3 sec	7.6 sec
Quarter Mile	12.7 sec	15.9 sec
Speed in 1/4 Mile	112.7 MPH	92.9 MPH

Fuel Economy and Range

The IS has 5 gallons more fuel capacity than the Integra (17.4 vs. 12.4 gallons), for longer range between fill-ups.

Transmission

To facilitate fast shifting and allow the driver to focus on the road, the IS F Sport has a standard up-shift light to indicate when the engine is approaching redline. The Integra doesn’t offer an up-shift light.

Brakes and Stopping

For better stopping power the IS’ brake rotors are larger than those on the Integra:

	IS	IS 500 Performance	Integra	Integra Type S
Front Rotors	13.1 inches	14 inches	12.3 inches	13.8 inches
Rear Rotors	11.7 inches	12.7 inches	11.1 inches	12 inches

The IS’ standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Integra are solid, not vented.

The IS stops much shorter than the Integra:

	IS	Integra
70 to 0 MPH	159 feet	178 feet	Car and Driver
60 to 0 MPH	110 feet	123 feet	Motor Trend

Tires and Wheels

For better traction, the IS has larger standard tires than the Integra (235/45R18 vs. 215/50R17).

The IS 300’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 Integra’s standard 50 series tires.

For better ride, handling and brake cooling the IS 300 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Integra.

Suspension and Handling

The IS 500 F Sport’s has front and rear gas-charged shocks for better control over choppy roads. The Integra’s suspension doesn’t offer front gas-charged shocks.

For a smoother ride and more stable handling, the IS’ wheelbase is 2.5 inches longer than on the Integra (110.2 inches vs. 107.7 inches).

The IS’ front to rear weight distribution is more even (54% to 46%) than the Integra’s (60% to 40%). This gives the IS more stable handling and braking.

The IS 350 F Sport handles at .93 G’s, while the Integra A-Spec Technology pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The IS 500 Performance executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the Integra A-Spec Technology (25.2 seconds @ .74 average G’s vs. 27.2 seconds @ .63 average G’s).

For better maneuverability, the IS’ turning circle is 3.9 feet tighter than the Integra’s (34.2 feet vs. 38.1 feet). The IS AWD’s turning circle is 4.3 feet tighter than the Integra Type S’ (35.4 feet vs. 39.7 feet).

Passenger Space

The IS has 2.5 inches more front legroom, .5 inches more rear headroom and 5.1 inches more rear hip room than the Integra.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the IS offers cargo security. The Integra’s hatchback body style and non-lockable folding seat defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the IS. The Integra doesn’t offer locking storage for small valuables.

Servicing Ease

The IS uses gas struts to support the hood for easier service access. The Integra uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the IS is mounted longitudinally (North-South), instead of sideways, as in the Integra. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Acura. J.D. Power ranks Lexus first in service department satisfaction. With a 26% lower rating, Acura is ranked 6th.

Ergonomics

Unlike the driver-only memory seat in the Integra A-Spec with Technology Package, the IS offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The IS’ instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Integra does not have an oil pressure gauge.

The IS’ front and rear power windows all 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 Integra’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the IS 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. (This window function must be activated by your Lexus service department.) The driver of the Integra can only close the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the IS’ headlight performance “Very Good,” a higher rating than the Integra’s headlights, which were rated “Good.”

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 IS’ headlights were rated “Good” to “Acceptable” by the IIHS, while the Integra’s headlights are rated “Acceptable.”

To help drivers see further while navigating curves, the IS offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Integra doesn’t offer cornering lights.

A power rear sunshade is optional in the IS to help block heat and glare for the rear passengers. The Integra doesn’t offer a rear sunshade.

The IS’ standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Integra has an automatic rear view mirror, but its side mirrors don’t dim.

Optional air-conditioned seats in the IS keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Integra doesn’t offer air-conditioned seats.

On extremely cold winter days, the IS’ optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Integra doesn’t offer a heated steering wheel.

The IS 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 Integra A-Spec with Technology Package/Type S.

Both the IS and the Integra offer rear vents. For greater rear passenger comfort, the IS has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Integra doesn’t offer rear air conditioning vents, only heat vents.

With optional Dynamic Voice Command, the IS offers the driver hands free control of the radio, climate controls and the navigation computer by simply speaking. The Integra doesn’t offer a voice control system.
