Over 200 people are killed each year when backed over by motor vehicles. The Integra offers an optional Low-Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Civic Si doesn’t offer backup collision prevention brakes.

The Integra A-Spec offers optional AcuraLink, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Civic Si doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Integra and the Civic Si 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, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, 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, driver alert monitors and available rear parking sensors.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Acura Integra is safer than the Civic Si:

	Integra	Civic Si

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 Civic Si was last only a “Top Safety Pick” in 2023 but no longer qualifies.

Warranty

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

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

Reliability

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than Honda vehicles. Consumer Reports ranks Acura fourth in overall reliability. Honda is ranked fifth.

Engine

The Integra Type S’ standard 2.0 turbo 4-cylinder produces 120 more horsepower (320 vs. 200) and 118 lbs.-ft. more torque (310 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder.

As tested in Motor Trend the Integra Type S 2.0 turbo 4-cylinder is faster than the Honda Civic Si (manual transmissions tested):

	Integra	Civic Si
Zero to 60 MPH	5.2 sec	7.1 sec
Quarter Mile	13.8 sec	15.3 sec
Speed in 1/4 Mile	105.1 MPH	92.8 MPH

Fuel Economy and Range

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 Civic Si doesn’t offer an automatic engine start/stop system.

Transmission

The Integra offers an optional automatic transmission, for driver comfort, especially in the city. The Civic Si doesn’t offer an automatic 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 Civic Si doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the Integra Type S’ brake rotors are larger than those on the Civic Si:

	Integra Type S	Civic Si
Front Rotors	13.8 inches	12.3 inches
Rear Rotors	12 inches	11.1 inches

The Integra stops much shorter than the Civic Si:

	Integra	Civic Si
70 to 0 MPH	153 feet	160 feet	Car and Driver
60 to 0 MPH	100 feet	110 feet	Motor Trend
60 to 0 MPH (Wet)	137 feet	147 feet	Consumer Reports

Tires and Wheels

For better traction, the Integra Type S’ tires are larger than the largest tires available on the Civic Si (265/30R19 vs. 235/40R18).

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 Civic Si’s 40 series tires.

For better ride, handling and brake cooling the Integra Type S has standard 19-inch wheels. The Civic Si’s largest wheels are only 18-inches.

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 Civic Si doesn’t offer vehicle monitored tire inflation.

The Integra offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Civic Si; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The Integra offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Civic Si’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the average track (width between the wheels) on the Integra is 1.8 inches wider in the front and .8 inches wider in the rear than the track on the Civic Si.

The Integra Type S handles at 1.02 G’s, while the Civic Si pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The Integra Type S executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Civic Si (24.7 seconds @ .78 average G’s vs. 26.3 seconds @ .67 average G’s).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Integra a Large car, while the Civic Si is rated a Mid-size.

Cargo Capacity

To allow full utilization of available cargo room, the Integra’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. Its intrusive beam hinge reduces the Civic Si’s useful trunk space.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than Honda. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 36% lower rating, Honda is ranked 25th.

Ergonomics

The Integra A-Spec CVT with Technology Package has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Civic Si doesn’t offer a remote starting system.

When two different drivers share the Integra A-Spec with Technology Package, the memory seats make it convenient for both. Each setting activates different, customized memories for the driver’s seat position. The Civic Si doesn’t offer memory seats.

The Integra’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The Civic Si doesn’t offer an easy entry system.

The Integra A-Spec with Technology Package/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 Civic Si 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 Civic Si’s passenger power window switches are unlit, making them difficult to find at night and operate safely.

The Integra A-Spec with Technology Package/Type S’ standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Civic Si’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

When the Integra A-Spec with Technology Package is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Civic Si’s mirror doesn’t automatically adjust for backing.

The Integra’s standard rear view mirror has an automatic dimming feature. This mirror can be set to automatically darken quickly when headlights shine on it, keeping following vehicles from blinding or distracting the driver. The Civic Si doesn’t offer the luxury of an automatic dimming rear view mirror.

The Integra has standard heated front seats, which keep the driver and front passenger extremely comfortable in the winter. Heated seats aren’t available in the Civic Si.

The Integra A-Spec with Technology Package/Type S’ 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. The Civic Si doesn’t offer dual zone air conditioning.

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