In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Integra are reminded to check the back seat if they opened the rear door before starting out. The IS doesn’t offer a back seat reminder.

The Integra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The IS doesn’t offer a driver alert monitor.

Both the Integra and the IS 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, rear cross-path warning and available rear parking sensors.

The Acura Integra has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The IS has not yet been fully evaluated by the IIHS for 2024.

Warranty

There are over 11 percent more Acura dealers than there are Lexus dealers, which makes it easier should you ever need service under the Integra’s warranty.

Reliability

A hardened steel chain, with no maintenance needs, drives the camshafts in the Integra’s engine. A rubber cam drive belt that needs periodic replacement drives the IS’ camshafts. If the IS’ belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

Fuel Economy and Range

On the EPA test cycle the Integra gets better mileage than the IS:

			MPG
Integra
FWD	Manual	1.5 turbo 4-cyl.	26 city/36 hwy
		2.0 turbo 4-cyl.	21 city/28 hwy
	Auto	1.5 turbo 4-cyl.	30 city/37 hwy
		A-Spec 1.5 turbo 4-cyl.	29 city/36 hwy
IS
	Auto	5.0 V8	17 city/25 hwy
		2.0 turbo 4-cyl.	21 city/31 hwy
		3.5 DOHC V6	20 city/28 hwy
AWD	Auto	350 F Sport 3.5 DOHC V6	19 city/26 hwy
		300 AWD 3.5 DOHC V6	19 city/26 hwy

In heavy traffic or at stoplights the Integra (except Type S)’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The IS doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Acura Integra uses regular unleaded gasoline (premium recommended for maximum performance). The IS requires premium, which can cost on average about 84.9 cents more per gallon.

The Integra has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The IS doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Acura Integra higher (6 to 7 out of 10) than the Lexus IS (5). This means the Integra produces up to 8 pounds less smog-producing pollutants than the IS every 15,000 miles.

The EPA certifies the Acura Integra at emission levels ranging from “Ultra Low Emissions Vehicle” (ULEV) to “Super Ultra Low Emissions Vehicle” (SULEV). The Lexus IS is only certified to “Ultra Low Emissions Vehicle” (ULEV) standards.

Transmission

The Integra offers a manual transmission for better acceleration, control and sportiness. The IS doesn’t offer a manual transmission.

The Integra has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The IS doesn’t offer a CVT.

Brakes and Stopping

The Integra stops much shorter than the IS:

	Integra	IS
100 to 0 MPH	305 feet	320 feet	Car and Driver
70 to 0 MPH	153 feet	159 feet	Car and Driver
60 to 0 MPH	100 feet	117 feet	Motor Trend
60 to 0 MPH (Wet)	137 feet	141 feet	Consumer Reports

Tires and Wheels

For better traction, the Integra Type S’ tires are larger than the largest tires available on the IS (265/30R19 vs. 235/40R19).

The Integra Type S’ tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the IS F Sport’s 40 series front and 35 series rear tires.

The Integra 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 IS doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Integra Type S handles at 1.02 G’s, while the IS 500 Performance pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The Integra Type S executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the IS 300 AWD (24.7 seconds @ .78 average G’s vs. 25.9 seconds @ .7 average G’s).

The Acura Integra may be more efficient, handle and accelerate better because it weighs about 650 pounds less than the Lexus IS.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Integra a Large car, while the IS is rated a Compact.

The Integra has 5.6 cubic feet more passenger volume than the IS (95.8 vs. 90.2).

The Integra has .4 inches more front headroom, 1.1 inches more front shoulder room, 5.2 inches more rear legroom and 2.6 inches more rear shoulder room than the IS.

Ergonomics

The Integra’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the IS.

The Integra A-Spec Technology/Type S has a standard heads-up display that projects speed and warning readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The IS doesn’t offer a heads-up display.

The Integra’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The IS’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The Integra’s standard 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 IS’ standard manually variable intermittent wipers have to be constantly adjusted.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Integra has standard extendable sun visors. The IS doesn’t offer extendable visors.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura Integra A-Spec Technology/Type S has a standard wireless phone charging system (Qi) in the front center console. The IS doesn’t offer wireless personal charging.

Economic Advantages

Insurance will cost less for the Integra owner. The Complete Car Cost Guide estimates that insurance for the Integra will cost $1795 to $10300 less than the IS over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura Integra will be $8649 to $35052 less than for the Lexus IS.
