The 3 Series Sedan’s 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 3 Series Sedan has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Integra doesn’t offer a whiplash protection system.

The 3 Series Sedan has a standard PostCrash iBrake, 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 3 Series Sedan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Integra doesn’t offer all-wheel drive.

The 3 Series Sedan M340i offers an optional Surround View 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 3 Series Sedan and the Integra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

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 vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 3 Series Sedan the rating of “Top Safety Pick” for 2022, a rating granted to only 155 vehicles tested by the IIHS. The Integra has not been tested, yet.

Warranty

The 3 Series Sedan’s corrosion warranty is 7 years longer than the Integra’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the 3 Series Sedan for 1 year and 12000 miles longer than Acura pays for maintenance for the Integra (3/36,000 vs. 2/24,000).

There are over 30 percent more BMW dealers than there are Acura dealers, which makes it easier should you ever need service under the 3 Series Sedan’s warranty.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Acura vehicles. J.D. Power ranks BMW above average in initial quality. With 27 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 BMW vehicles are more reliable than Acura vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 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 2021 Auto Issue reports that BMW vehicles are more reliable than Acura vehicles. Consumer Reports ranks BMW 16 places higher in reliability than Acura.

Engine

The 330i’s standard 2.0 turbo 4-cylinder produces 55 more horsepower (255 vs. 200) and 102 lbs.-ft. more torque (294 vs. 192) than the Integra’s 1.5 turbo 4-cylinder. The M340i’s standard 3.0 turbo 6-cylinder hybrid produces 182 more horsepower (382 vs. 200) and 176 lbs.-ft. more torque (368 vs. 192) than the Integra’s 1.5 turbo 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The Integra doesn’t offer a regenerative braking system.

The 3 Series Sedan has 3.2 gallons more fuel capacity than the Integra (15.6 vs. 12.4 gallons), for longer range between fill-ups.

Transmission

The 3 Series Sedan’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Integra doesn’t offer launch control.

Brakes and Stopping

For better stopping power the 3 Series Sedan’s brake rotors are larger than those on the Integra:

	330i	M340i	Integra
Front Rotors	13 inches	13.7 inches	12.3 inches
Rear Rotors	13 inches	13.6 inches	11.1 inches

The 3 Series Sedan’s 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 3 Series Sedan stops much shorter than the Integra:

	3 Series Sedan	Integra
70 to 0 MPH	151 feet	178 feet	Car and Driver

Tires and Wheels

For better traction, the 3 Series Sedan has larger standard tires than the Integra (225/45R18 vs. 215/50R17).

The 330i’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. The 3 Series Sedan’s optional 255/35R19 rear tires have a lower 35 series profile than the Integra A-Spec’s 40 series tires.

For better ride, handling and brake cooling the 330i has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Integra. The 3 Series Sedan’s optional 19-inch wheels are larger than the 18-inch wheels on the Integra A-Spec.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 3 Series Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Integra doesn’t offer run-flat tires.

Suspension and Handling

The 3 Series Sedan has standard front and rear gas-charged shocks for better control over choppy roads. The Integra’s suspension doesn’t offer gas-charged shocks.

For a smoother ride and more stable handling, the 3 Series Sedan’s wheelbase is 4.5 inches longer than on the Integra (112.2 inches vs. 107.7 inches).

For better handling and stability, the average track (width between the wheels) on the 3 Series Sedan is 1.8 inches wider in the front and .7 inches wider in the rear than the track on the Integra.

The 3 Series Sedan’s front to rear weight distribution is more even (51.3% to 48.7%) than the Integra’s (60% to 40%). This gives the 3 Series Sedan more stable handling and braking.

The 330i handles at .99 G’s, while the Integra A-Spec Technology pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The front grille of the 3 Series Sedan uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Integra doesn’t offer active grille shutters.

As tested by Car and Driver while cruising at 70 MPH, the interior of the 330i is quieter than the Integra A-Spec Technology (69 vs. 71 dB).

Passenger Space

The 3 Series Sedan has 1.1 inches more front headroom and 1.2 inches more rear headroom than the Integra.

Cargo Capacity

Pulling a handle automatically lowers the 3 Series Sedan’s rear seats, to make changing between passengers and cargo easier. The Integra doesn’t offer automatic folding seats.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 3 Series 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 3 Series Sedan. The Integra doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the 3 Series Sedan offers an optional power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Integra doesn’t offer a power liftgate.

Servicing Ease

The 3 Series Sedan 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 3 Series Sedan 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.

Ergonomics

The power windows standard on both the 3 Series Sedan and the Integra have locks to prevent small children from operating them. When the lock on the 3 Series Sedan is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Integra prevents the driver from operating the other windows just as it does the other passengers.

The 3 Series Sedan’s 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 3 Series Sedan the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Integra can only close the windows from inside the vehicle, with the ignition on.

The 3 Series Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Integra’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers avoid possible obstacles, the 3 Series Sedan has standard cornering lights to illuminate around corners when the turn signals are activated. The Integra doesn’t offer cornering lights. The 3 Series Sedan also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The 3 Series Sedan’s 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.

Both the 3 Series Sedan and the Integra offer available heated front seats. The 3 Series Sedan also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Integra.

On extremely cold winter days, the 3 Series Sedan’s 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 3 Series Sedan 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.

Both the 3 Series Sedan and the Integra offer rear vents. For greater rear passenger comfort, the 3 Series Sedan 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 standard voice command, the 3 Series Sedan 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.

The 3 Series Sedan M340i’s optional Automatic Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Integra doesn’t offer an automated parking system.
