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 Accord 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 Accord 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 Accord 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 Accord doesn’t offer all-wheel drive.

The 3 Series Sedan offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Accord 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 Accord 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.

Warranty

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

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

BMW pays for scheduled maintenance on the 3 Series Sedan for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Honda doesn’t pay scheduled maintenance for the Accord.

Reliability

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 Accord’s battery is in the hot engine compartment.

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 Honda 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, Honda is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that BMW vehicles are more reliable than Honda vehicles. Consumer Reports ranks BMW third in overall reliability. Honda is ranked fifth.

Engine

The 330i’s standard 2.0 turbo 4-cylinder produces 63 more horsepower (255 vs. 192) and 103 lbs.-ft. more torque (295 vs. 192) than the Accord’s standard 1.5 turbo 4-cylinder. The 330i’s 2.0 turbo 4-cylinder produces 3 more horsepower (255 vs. 252) and 22 lbs.-ft. more torque (295 vs. 273) than the Accord’s optional 2.0 turbo 4-cylinder. The M340i’s standard 3.0 turbo 6-cylinder hybrid produces 130 more horsepower (382 vs. 252) and 96 lbs.-ft. more torque (369 vs. 273) than the Accord’s optional 2.0 turbo 4-cylinder.

As tested in Car and Driver the BMW 3 Series Sedan is faster than the Honda Accord:

	330i	M340i	Accord 1.5	Accord 2.0
Zero to 60 MPH	5.1 sec	3.7 sec	7.3 sec	5.5 sec
5 to 60 MPH Rolling Start	6.5 sec	4.5 sec	8 sec	6.1 sec
Passing 30 to 50 MPH	3.2 sec	n/a	4 sec	3.4 sec
Passing 50 to 70 MPH	3.9 sec	n/a	5.2 sec	4.4 sec

Speed in 1/4 Mile	100 MPH	112 MPH	91 MPH	102 MPH
Top Speed	155 MPH	150 MPH	121 MPH	126 MPH

Fuel Economy and Range

On the EPA test cycle the 3 Series Sedan gets better mileage than the Accord:

			MPG
3 Series Sedan
	RWD	2.0 turbo 4-cyl.	25 city/34 hwy
	AWD	2.0 turbo 4-cyl.	24 city/33 hwy
Accord
	FWD	2.0 turbo 4-cyl.	22 city/32 hwy

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

Regardless of its engine, the 3 Series Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. Honda only offers an automatic engine start/stop system on the Accord 1.5T.

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 Accord 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 Accord:

	330i	M340i	Accord	Accord Sport/Touring
Front Rotors	13 inches	13.7 inches	11.5 inches	12.3 inches
Rear Rotors	13 inches	13.6 inches	11.1 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 Accord are solid, not vented.

The 3 Series Sedan stops much shorter than the Accord:

	3 Series Sedan	Accord
70 to 0 MPH	151 feet	176 feet	Car and Driver
60 to 0 MPH	103 feet	135 feet	Motor Trend
60 to 0 MPH (Wet)	135 feet	142 feet	Consumer Reports

Tires and Wheels

The 3 Series Sedan’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 Accord’s standard 50 series tires. The 3 Series Sedan’s optional 255/35R19 rear tires have a lower 35 series profile than the Accord Sport/Touring’s 40 series tires.

For better ride, handling and brake cooling the 3 Series Sedan has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Accord.

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 Accord doesn’t offer run-flat tires.

Suspension and Handling

The 3 Series Sedan’s front to rear weight distribution is more even (51.2% to 48.8%) than the Accord’s (59.8% to 40.2%). This gives the 3 Series Sedan more stable handling and braking.

The 330i handles at .95 G’s, while the Accord pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The M340i executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the Accord (25 seconds @ .77 average G’s vs. 27.7 seconds @ .61 average G’s).

Chassis

The 3 Series Sedan is 10.2 inches shorter than the Accord, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver, the interior of the 330i is quieter than the Accord Sport:

	3 Series Sedan	Accord
At idle	38 dB	41 dB
Full-Throttle	74 dB	78 dB
70 MPH Cruising	69 dB	70 dB

Cargo Capacity

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. Its intrusive beam hinge reduces the Accord’s useful trunk space.

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

The 3 Series Sedan’s standard folding rear seats are split to accommodate bulky cargo. The Accord LX’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 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 Accord doesn’t offer a power trunk.

Servicing Ease

The 3 Series Sedan uses gas struts to support the hood for easier service access. The Accord 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 Accord. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Honda. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 31% lower rating, Honda is ranked 25th.

Ergonomics

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

The 3 Series Sedan’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 Accord’s power window (except driver window), power lock and power mirror switches are unlit, making them difficult to find at night and operate safely.

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 Accord’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 Accord 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 outside mirrors include heating elements to clear off the mirrors for better visibility. Honda only offers heated mirrors on the Accord Sport 2.0T/Sport SE/EX-L/Touring.

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 Accord offers an automatic rear view mirror, but its side mirrors don’t dim.

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 Accord doesn’t offer a heated steering wheel.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 3 Series has a standard wireless phone charging system (Qi) in the center console. Only the Accord EX-L/Sport 2.0T/Touring offers wireless charging.

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

Economic Advantages

Insurance will cost less for the 3 Series Sedan owner. The Car Book by Jack Gillis rates the 3 Series Sedan with a number “3” insurance rate while the Accord is rated higher at a number “8” rate.

According to The Car Book by Jack Gillis, the 3 Series Sedan is less expensive to operate than the Accord because typical repairs cost much less on the 3 Series Sedan than the Accord, including $307 less for a fuel pump and $172 less for a power steering pump.
