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 K5 doesn’t offer pre-crash pretensioners.

The BMW 3 Series Sedan has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The K5 doesn’t offer a front passenger side knee airbag.

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 K5 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 K5 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.

Both the 3 Series Sedan and the K5 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, lane departure warning systems, rearview cameras, driver alert monitors, available all wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

The 3 Series Sedan’s corrosion warranty is 7 years and unlimited miles longer than the K5’s (12/unlimited vs. 5/100,000).

BMW pays for scheduled maintenance on the 3 Series Sedan for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Kia doesn’t pay scheduled maintenance for the K5.

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 K5’s battery is in the hot engine compartment.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the 3 Series Sedan’s reliability 27 points higher than the K5.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that BMW vehicles are more reliable than Kia vehicles. Consumer Reports ranks BMW 3 places higher in reliability than Kia.

Engine

The 330i’s standard 2.0 turbo 4-cylinder produces 75 more horsepower (255 vs. 180) and 99 lbs.-ft. more torque (294 vs. 195) than the K5 1.6T’s standard 1.6 turbo 4-cylinder. The M340i’s standard 3.0 turbo 6-cylinder hybrid produces 92 more horsepower (382 vs. 290) and 57 lbs.-ft. more torque (368 vs. 311) than the K5 GT 2.5T’s standard 2.5 turbo 4-cylinder.

As tested in Motor Trend the 330i 2.0 turbo 4-cylinder is faster than the K5 1.6T 1.6 turbo 4-cylinder:

	3 Series Sedan	K5
Zero to 60 MPH	5.4 sec	7.8 sec
Quarter Mile	14 sec	16 sec
Speed in 1/4 Mile	98.1 MPH	87.4 MPH

Fuel Economy and Range

On the EPA test cycle the 3 Series Sedan gets better mileage than the K5:

			MPG
3 Series Sedan
	RWD	2.0 turbo 4-cyl.	26 city/36 hwy
	AWD	2.0 turbo 4-cyl.	25 city/34 hwy
K5
	FWD	2.5 turbo 4-cyl.	24 city/32 hwy
	AWD	1.6 turbo 4-cyl.	25 city/33 hwy

Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The K5 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. Kia only offers an automatic engine start/stop system on the K5 LX.

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 K5 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 K5:

	330i	M340i	K5	K5 GT
Front Rotors	13 inches	13.7 inches	12 inches	13.6 inches
Rear Rotors	13 inches	13.6 inches	11.2 inches	12.8 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 K5 are solid, not vented.

The 3 Series Sedan stops much shorter than the K5:

	3 Series Sedan	K5
70 to 0 MPH	151 feet	179 feet	Car and Driver
60 to 0 MPH	103 feet	127 feet	Motor Trend
60 to 0 MPH (Wet)	135 feet	140 feet	Consumer Reports

Tires and Wheels

For better traction, the 3 Series Sedan has larger standard tires than the K5 (225/45R18 vs. 205/65R16).

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 K5 LX/LXS’ standard 65 series tires. The 3 Series Sedan’s optional 225/35R20 front and 255/30R20 rear tires have a lower 35 series front and 30 series rear profile than the K5 GT’s 40 series tires.

For better ride, handling and brake cooling the 330i has standard 18-inch wheels. Smaller 16-inch wheels are standard on the K5 LX/LXS. The 3 Series Sedan’s optional 20-inch wheels are larger than the 19-inch wheels on the K5 GT.

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 K5 doesn’t offer run-flat tires.

Suspension and Handling

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 K5’s suspension doesn’t offer adjustable shock absorbers.

The 3 Series Sedan’s front to rear weight distribution is more even (51.3% to 48.7%) than the K5’s (60% to 40%). This gives the 3 Series Sedan more stable handling and braking.

The 330i handles at .99 G’s, while the K5 EX pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The M340i executes Motor Trend’s “Figure Eight” maneuver 2.4 seconds quicker than the K5 EX (25 seconds @ .77 average G’s vs. 27.4 seconds @ .62 average G’s).

Chassis

The 3 Series Sedan is 7.4 inches shorter than the K5, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.

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 K5 doesn’t offer active grille shutters.

Cargo Capacity

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 26.7 inches, while the K5’s liftover is 28.6 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 K5’s useful trunk space is reduced by its intrusive beam hinge.

The 3 Series Sedan’s standard rear seats fold to accommodate long and bulky cargo. The K5 LX doesn’t offer folding rear seats.

Pulling a handle automatically lowers the 3 Series Sedan’s rear seats, to make changing between passengers and cargo easier. The K5 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 K5’s non-lockable remote release defeats 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 K5 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 K5 doesn’t offer a power trunk.

Servicing Ease

The engine in the 3 Series Sedan is mounted longitudinally (North-South), instead of sideways, as in the K5. 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 Kia. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 11% lower rating, Kia is ranked 16th.

Ergonomics

The 3 Series Sedan offers an optional heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The K5 doesn’t offer a heads-up display.

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 K5’s standard passenger windows don’t open or close automatically.

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 K5 can only operate 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 K5’s manually variable intermittent wipers have to be constantly adjusted.

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 K5 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.

When the 3 Series Sedan is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The K5’s mirror doesn’t automatically adjust for backing.

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 K5 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the 3 Series Sedan and the K5 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 K5.

Both the 3 Series Sedan and the K5 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 K5 doesn’t offer rear air conditioning vents, only heat vents.

The 3 Series Sedan’s available Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The K5’s automatic parking system requires operating the brakes and transmission to safely park.
