For enhanced safety, the front and rear seat shoulder belts of the Acura Integra have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 3 Series Sedan doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Acura Integra are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 3 Series Sedan doesn’t offer height-adjustable seat belts.

The Integra’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 3 Series Sedan.

The Integra has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 3 Series Sedan’s blind spot costs extra.

To help make backing out of a parking space safer, the Integra has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the 3 Series Sedan.

Both the Integra and the 3 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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 and available rear parking sensors.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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 3 Series Sedan has not yet been fully evaluated by the IIHS for 2024.

Warranty

Acura’s powertrain warranty covers the Integra 2 years and 20,000 miles longer than BMW covers the 3 Series Sedan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 3 Series Sedan ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Acura above average in initial quality. With 13 more problems per 100 vehicles, BMW is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than BMW vehicles. Consumer Reports ranks Acura fourth in overall reliability. BMW is ranked 9th.

Fuel Economy and Range

On the EPA test cycle the Integra gets better mileage than the 3 Series Sedan running its gasoline engine:

			MPG
Integra
FWD	Manual	1.5 turbo 4-cyl.	26 city/36 hwy
	Auto	1.5 turbo 4-cyl.	30 city/37 hwy
		A-Spec 1.5 turbo 4-cyl.	29 city/36 hwy
3 Series Sedan
	Auto	2.0 turbo 4-cyl.	25 city/34 hwy
		2.0 turbo 4-cyl. Hybrid	24 city/32 hwy
		3.0 turbo 6-cyl. Hybrid	23 city/31 hwy
AWD	Auto	2.0 turbo 4-cyl.	24 city/33 hwy
		3.0 turbo 6-cyl. Hybrid	23 city/31 hwy
		2.0 turbo 4-cyl. Hybrid	22 city/32 hwy

To lower fuel costs and make buying fuel easier, the Acura Integra uses regular unleaded gasoline (premium recommended for maximum performance). The 3 Series Sedan requires premium, which can cost on average about 84.9 cents more per gallon.

The Integra has 1.8 gallons more fuel capacity than the 3 Series Sedan 330e’s standard fuel tank (12.4 vs. 10.6 gallons), for longer range between fill-ups.

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 3 Series Sedan 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 BMW 3 Series Sedan (5 to 7). This means the Integra produces up to 8 pounds less smog-producing pollutants than the 3 Series Sedan every 15,000 miles.

Transmission

The Integra offers a manual transmission for better acceleration, control and sportiness. The 3 Series Sedan 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 3 Series Sedan doesn’t offer a CVT.

Brakes and Stopping

The Integra stops much shorter than the 3 Series Sedan:

	Integra	3 Series Sedan
100 to 0 MPH	305 feet	310 feet	Car and Driver
70 to 0 MPH	153 feet	165 feet	Car and Driver
60 to 0 MPH	100 feet	114 feet	Motor Trend

Tires and Wheels

For better traction, the Integra Type S’ tires are larger than the largest tires available on the 3 Series Sedan (265/30R19 vs. 225/40R19).

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 3 Series Sedan’s optional 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 3 Series Sedan doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Integra Type S handles at 1.02 G’s, while the 330i xDrive 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 1.9 seconds quicker than the 330i xDrive (24.7 seconds @ .78 average G’s vs. 26.6 seconds @ .66 average G’s).

For better maneuverability, the Integra’s turning circle is 1.3 feet tighter than the 3 Series Sedan’s (38.1 feet vs. 39.4 feet).

Chassis

The Acura Integra may be more efficient, handle and accelerate better because it weighs about 450 to 950 pounds less than the BMW 3 Series Sedan.

Passenger Space

The Integra has .3 inches more front legroom, 1 inch more front shoulder room, 2.2 inches more rear legroom and 1.4 inches more rear shoulder room than the 3 Series Sedan.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than BMW. J.D. Power ranks Acura 9th in service department satisfaction (above the industry average). With an 8% lower rating, BMW is ranked 13th.

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. The 3 Series Sedan doesn’t offer an easy entry system.

The Integra’s standard Keyless Access System allows you to unlock the doors from either front door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Comfort Go standard on the 3 Series Sedan only offers hands-free access for the ignition, none to unlock the car.

Consumer Reports rated the Integra’s headlight performance “Good,” a higher rating than the 3 Series Sedan’s headlights, which were rated “Fair.”

Economic Advantages

Insurance will cost less for the Integra owner. The Complete Car Cost Guide estimates that insurance for the Integra will cost $325 to $7360 less than the 3 Series Sedan 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 $11242 to $28404 less than for the BMW 3 Series Sedan.
