Safety Comparison

The 3 Series Sedan’s optional front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The ILX doesn’t offer pre-crash pretensioners.

The 3 Series Sedan offers optional City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The ILX doesn't offer collision warning or crash mitigation brakes.

The 3 Series Sedan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ILX doesn’t offer all-wheel drive.

The 3 Series Sedan (except 320i)’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The ILX doesn’t offer a lane departure warning system.

The 3 Series Sedan (except 320i) offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The ILX only offers a rear monitor.

The 3 Series Sedan (except 320i)’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The ILX doesn’t offer a system to reveal objects in the driver’s blind spots.

The 3 Series Sedan has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to 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 ILX doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the 3 Series Sedan and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

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

BMW pays for scheduled maintenance on the 3 Series Sedan for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Acura doesn’t pay scheduled maintenance for the ILX.

There are over 28 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 Comparison

To reliably power the ignition and other systems and to recharge the battery, the 3 Series Sedan has a standard 170-amp alternator (180-amp - 3 Series Sedan Diesel and 200 ActiveHybrid). The ILX’s standard 95-amp alternator and largest (2.4L) 105-amp alternator aren’t as powerful.

The battery on the 3 Series Sedan is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the 3 Series Sedan’s battery 20 to 30 degrees cooler, its life is increased by years. The ILX’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2014 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 8th in initial quality, above the industry average. With 23 more problems per 100 vehicles, Acura is ranked 25th, below the industry average.

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

In heavy traffic or at stoplights the 3 Series Sedan’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The ILX doesn’t offer an automatic engine start/stop system.

The 3 Series Sedan ActiveHybrid/diesel’s standard fuel tank has 1.8 gallons more fuel capacity than the ILX (15 vs. 13.2 gallons), for longer range between fill-ups. The 3 Series Sedan’s standard fuel tank has 2.6 gallons more fuel capacity than the ILX (15.8 vs. 13.2 gallons).

Consumer Reports

Tires and Wheels Comparison

For better traction, the 3 Series Sedan has larger standard tires than the ILX (225/50R17 vs. 215/45R17). The 3 Series Sedan’s optional tires are larger than the largest tires available on the ILX (F:225/40R19 & R:255/35R19 vs. 215/45R17).

The 3 Series Sedan’s optional 225/40R19 front and 255/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the ILX’s 45 series tires.

For better ride, handling and brake cooling the 3 Series Sedan offers optional 19-inch wheels. The ILX’s largest wheels are only 17-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard 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 ILX doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 3 Series Sedan 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 ILX’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the 3 Series Sedan’s wheelbase is 5.5 inches longer than on the ILX (110.6 inches vs. 105.1 inches).

For better handling and stability, the track (width between the wheels) on the 3 Series Sedan is .9 inches wider in the front and 1.6 inches wider in the rear than on the ILX.

The 3 Series Sedan’s front to rear weight distribution is more even (49.9% to 50.1%) than the ILX’s (60.8% to 39.2%). This gives the 3 Series Sedan more stable handling and braking.

The 320i handles at .92 G’s, while the ILX 2.4L pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The 335i xDrive executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the ILX 2.4L (25.6 seconds @ .75 average G’s vs. 27.9 seconds @ .56 average G’s).

Passenger Space Comparison

The 3 Series Sedan has 6.7 cubic feet more passenger volume than the ILX (96 vs. 89.3).

The 3 Series Sedan has 2.3 inches more front headroom, 1.8 inches more rear headroom, 1.1 inches more rear legroom and 1.6 inches more rear shoulder room than the ILX.

Cargo Capacity Comparison

The 3 Series Sedan has a larger trunk than the ILX (13 vs. 12.3 cubic feet).

A low lift-over trunk design makes loading and unloading the 3 Series Sedan easier. The 3 Series Sedan’s trunk lift-over height is 26 inches, while the ILX’s liftover is 28.7 inches.

To allow full utilization of available cargo room, the 3 Series Sedan’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The ILX’s useful trunk space is reduced by its intrusive beam hinge.

The 3 Series Sedan’s optional folding rear seats are split to accommodate bulky cargo. The ILX’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

To make loading groceries and cargo easier when your hands are full, the 3 Series Sedan’s available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The ILX doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

When two different drivers share the 3 Series Sedan, the optional memory system makes it convenient for both. Each keyless remote activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The ILX doesn’t offer a memory system.

The 3 Series Sedan (except 320i) offers an available heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The ILX doesn’t offer a heads-up display.

The power windows standard on both the 3 Series Sedan and the ILX 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 ILX 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 ILX’s rear power window switches have to be held the entire time to open or close them fully.

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 ILX’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the 3 Series Sedan to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The ILX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 3 Series Sedan offers available headlight washers to keep headlight output high. The ILX doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 3 Series Sedan (except 320i) detect other vehicles which could be blinded and automatically switch to low beams. The ILX doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the 3 Series Sedan offers optional cornering lights to illuminate around corners when the turn signals are activated. The ILX 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.

A power rear sunshade is optional in the 3 Series Sedan (except 320i) to help block heat and glare for the rear passengers. The ILX doesn’t offer a rear sunshade.

The 3 Series Sedan offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The ILX offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the 3 Series Sedan and the ILX 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 ILX.

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 ILX doesn’t offer a heated steering wheel.

Both the 3 Series Sedan and the ILX 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 ILX doesn’t offer rear air conditioning vents, only heat vents.

To keep a safe, consistent following distance, the 3 Series Sedan (except Manual/320i) offers an optional Active Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The ILX doesn’t offer an adaptive cruise control.

The 3 Series Sedan (except 320i)’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ILX doesn’t offer an automated parking system.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the 3 Series Sedan is less expensive to operate than the ILX because it costs $828 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the 3 Series Sedan than the ILX, including $59 less for a starter, $100 less for a fuel pump and $284 less for a power steering pump.
