For enhanced safety, the front and rear seat shoulder belts of the Acura TLX 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 TLX 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 TLX’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.

Both the TLX 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura TLX is safer than the BMW 3 Series Sedan:

	TLX	3 Series Sedan
	Driver
STARS	5 Stars	5 Stars
HIC	143	145
Neck Injury Risk	20%	23%
Neck Stress	175 lbs.	207 lbs.
Neck Compression	27 lbs.	32 lbs.

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

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Acura TLX is safer than the BMW 3 Series Sedan:

	TLX	3 Series Sedan
	Front Seat
STARS	5 Stars	5 Stars
Chest Movement	.8 inches	.8 inches
	Rear Seat
STARS	5 Stars	5 Stars
HIC	181	305
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	13 inches
Spine Acceleration	33 G’s	39 G’s
Hip Force	484 lbs.	544 lbs.

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

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 standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the TLX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 112 vehicles tested by the IIHS. The 3 Series Sedan is only a standard “Top Safety Pick” for 2022.

Warranty

Acura’s powertrain warranty covers the TLX 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.

Engine

The TLX’s standard 2.0 turbo 4-cylinder produces 17 more horsepower (272 vs. 255) than the 330i’s standard 2.0 turbo 4-cylinder.

As tested in Motor Trend the TLX Type S 3.0 turbo V6 is faster than the 330i 2.0 turbo 4-cylinder:

	TLX	3 Series Sedan
Zero to 60 MPH	5.1 sec	5.5 sec
Quarter Mile	13.7 sec	14.1 sec
Speed in 1/4 Mile	101.8 MPH	98.1 MPH

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the TLX Type S’ fuel efficiency. The 3 Series Sedan doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Acura TLX uses regular unleaded gasoline (premium recommended for maximum performance). The 3 Series Sedan requires premium, which can cost 20 to 55 cents more per gallon.

The TLX 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.

Transmission

A 10-speed automatic is standard on the Acura TLX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 3 Series Sedan.

Brakes and Stopping

For better stopping power the TLX Type S’ brake rotors are larger than those on the 3 Series Sedan:

	TLX Type S	330i	M340i
Front Rotors	14.3 inches	13 inches	13.7 inches

The TLX stops shorter than the 3 Series Sedan:

	TLX	3 Series Sedan
60 to 0 MPH	112 feet	114 feet	Motor Trend

Tires and Wheels

For better traction, the TLX has larger standard tires than the 3 Series Sedan (235/50R18 vs. 225/45R18). The TLX Type S’ tires are larger than the largest tires available on the 3 Series Sedan (255/35R20 vs. 225/40R19).

The TLX Type S’ tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 3 Series Sedan’s optional 40 series front tires.

For better ride, handling and brake cooling the TLX Type S has standard 20-inch wheels. The 3 Series Sedan’s largest wheels are only 19-inches.

The TLX 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

For better handling and stability, the track (width between the wheels) on the TLX is 1.7 inches wider in the front and 2.3 inches wider in the rear than the average track on the 3 Series Sedan.

The TLX Type S handles at .96 G’s, while the 330i xDrive pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The TLX Type S executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the 330i xDrive (25 seconds @ .75 average G’s vs. 26.6 seconds @ .66 average G’s).

Chassis

The TLX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 3 Series Sedan doesn’t offer active noise cancellation.

Passenger Space

The TLX has .5 inches more front legroom, 2.2 inches more front shoulder room and .4 inches more rear shoulder room than the 3 Series Sedan.

Cargo Capacity

The TLX has a larger trunk than the 3 Series Sedan (13.5 vs. 13 cubic feet).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than BMW. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 5% lower rating, BMW is ranked 7th.

Ergonomics

The TLX’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.

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

Standard air-conditioned seats in the TLX A-Spec/Advance/Type S keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The 3 Series Sedan doesn’t offer air-conditioned seats.
