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 Passat 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 Passat doesn’t offer a whiplash protection system.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the City Collision Mitigation in the 3 Series Sedan as “Superior.” The Passat scores only 3 points and is rated only “Advanced.”
The 3 Series Sedan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Passat 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 Passat 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 Passat 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, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.
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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 3 Series Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 46 vehicles tested by the IIHS. The Passat was last qualified as only a standard “Top Pick” in 2017.
The 3 Series Sedan comes with free roadside assistance for 4 years unlimited miles. BMW will send help if you run out of gas, need a jump-start, lock your keys in or need any assistance on the road. Volkswagen doesn’t give free roadside assistance for the Passat.
The 3 Series Sedan’s corrosion warranty is 2 years longer than the Passat’s (12 vs. 10 years).
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. Volkswagen doesn’t pay scheduled maintenance for the Passat.
To reliably start during all conditions and help handle large electrical loads, the 3 Series Sedan has a standard 720-amp battery. The Passat’s 480-amp battery isn’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 Passat’s battery is in the hot engine compartment.
J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Volkswagen vehicles. J.D. Power ranks BMW 20th in initial quality. With 11 more problems per 100 vehicles, Volkswagen is ranked 25th.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Volkswagen vehicles. J.D. Power ranks BMW 7th in reliability, above the industry average. With 9 more problems per 100 vehicles, Volkswagen is ranked 12th.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Volkswagen vehicles. Consumer Reports ranks BMW 8 places higher in reliability than Volkswagen.
The 330i’s standard 2.0 turbo 4-cyl. produces 81 more horsepower (255 vs. 174) and 111 lbs.-ft. more torque (295 vs. 184) than the Passat’s 2.0 turbo 4-cyl. The M340i’s standard 3.0 turbo 6-cyl. produces 208 more horsepower (382 vs. 174) and 185 lbs.-ft. more torque (369 vs. 184) than the Passat’s 2.0 turbo 4-cyl.
On the EPA test cycle the 330i RWD gets better fuel mileage than the Passat (26 city/36 hwy vs. 25 city/36 hwy).
Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The Passat 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 Passat doesn’t offer an automatic engine start/stop system.
An eight-speed automatic is standard on the BMW 3 Series Sedan, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Passat.
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 Passat doesn’t offer launch control.
For better stopping power the 3 Series Sedan’s brake rotors are larger than those on the Passat:
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 Passat are solid, not vented.
The 3 Series Sedan stops much shorter than the Passat:
70 to 0 MPH
Car and Driver
For better traction, the 3 Series Sedan has larger standard tires than the Passat (225/45R18 vs. 215/55R17).
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 Passat Wolfsburg Edition’s standard 55 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 Passat SE R-Line’s 40 series tires.
For better ride, handling and brake cooling the 330i has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Passat Wolfsburg Edition. The 3 Series Sedan’s optional 20-inch wheels are larger than the 19-inch wheels on the Passat SE R-Line.
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 Passat doesn’t offer run-flat tires.
The 3 Series Sedan has standard front and rear gas-charged shocks for better control over choppy roads. The Passat’s suspension doesn’t offer gas-charged shocks.
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 Passat’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the 3 Series Sedan’s wheelbase is 1.8 inches longer than on the Passat (112.2 inches vs. 110.4 inches).
For better handling and stability, the track (width between the wheels) on the 3 Series Sedan is .2 inches wider in the front and 1.9 inches wider in the rear than on the Passat.
The 330i xDrive handles at .89 G’s, while the Passat pulls only .79 G’s of cornering force in a Car and Driver skidpad test.
The 3 Series Sedan is 6.2 inches shorter than the Passat, making the 3 Series Sedan easier to handle, maneuver and park in tight spaces.
The design of the BMW 3 Series Sedan amounts to more than styling. The 3 Series Sedan has an aerodynamic coefficient of drag of .26 Cd. That is lower than the Passat (.29) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the 3 Series Sedan get better fuel mileage.
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 Passat doesn’t offer active grille shutters.
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 Passat’s liftover is 28.2 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. Its intrusive beam hinge reduces the Passat’s useful trunk space.
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 Passat doesn’t offer a power trunk, so its trunk has to be closed manually.
The engine in the 3 Series Sedan is mounted longitudinally (North-South), instead of sideways, as in the Passat. This makes it easier to service and maintain, because the accessory belts are in front.
The 3 Series Sedan offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Passat doesn’t offer a heads-up display.
If the windows are left open on the 3 Series Sedan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Passat can’t use the remote to operate the windows.
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 Passat’s standard manually variable intermittent wipers have to be constantly adjusted.
The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The 3 Series Sedan’s available headlights were rated “Good” by the IIHS, while the Passat’s headlights are rated “Poor.”
While driving with high beams on, sensitive light sensors available for the 3 Series Sedan detect other vehicles which could be blinded and automatically switch to low beams. The Passat doesn’t offer automatic dimming high beams.
The Passat (except S/R-Line/GT)’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The 3 Series Sedan’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
The 3 Series Sedan’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Volkswagen only offers heated mirrors on the Passat SE R-Line.
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 Passat’s mirror doesn’t automatically adjust for backing.
The 3 Series Sedan has standard 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 Passat 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 Passat doesn’t offer a heated steering wheel.
The 3 Series Sedan has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Passat SE R-Line.
Both the 3 Series Sedan and the Passat 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 Passat 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 offers an optional wireless phone charging system (Qi) in the center console. The Passat doesn’t offer wireless personal charging.
The BMW 3 Series comes in sedan, four door hatchback and station wagon bodystyles; the Volkswagen Passat isn’t available as a four door hatchback or station wagon.
The BMW 3 Series outsold the Volkswagen Passat by 8% during 2018.
