Safety

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 300 doesn’t offer pre-crash pretensioners.

The 3 Series Sedan offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The 300 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 300 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, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems and rear cross-path warning.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the BMW 3 Series Sedan is safer than the 300:

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 300 was not even a standard “Top Pick” for 2016.

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 300’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The 3 Series Sedan’s corrosion warranty is 7 years and unlimited miles longer than the 300’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. Chrysler doesn’t pay scheduled maintenance for the 300.

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the 3 Series Sedan have an overhead cam design, rather than the old pushrod design of the 5.7 V8 in the 300.

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 Chrysler vehicles. J.D. Power ranks BMW 20th in initial quality. With 11 more problems per 100 vehicles, Chrysler 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 Chrysler vehicles. J.D. Power ranks BMW 7th in reliability, above the industry average. With 24 more problems per 100 vehicles, Chrysler is ranked 16th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Chrysler vehicles. Consumer Reports ranks BMW 16 places higher in reliability than Chrysler.

Regenerative brakes improve the 3 Series Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The 300 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 300 doesn’t offer an automatic engine start/stop system.

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 300 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 300:

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 standard on the 300 are solid, not vented.

The 3 Series Sedan stops much shorter than the 300:

Car and Driver

Tires and Wheels

For better traction, the 3 Series Sedan has larger standard tires than the 300 (225/45R18 vs. 215/65R17).

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 300 Touring’s 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 300S/300C/Limited’s 45 series tires.

For better ride, handling and brake cooling the 330i has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 300 Touring.

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

The 330i xDrive handles at .89 G’s, while the 300 Limited pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 3 Series Sedan’s turning circle is 1.3 feet tighter than the 300’s (37.4 feet vs. 38.7 feet).

Chassis

The BMW 3 Series Sedan may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the Chrysler 300.

The 3 Series Sedan is 1 foot shorter than the 300, 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 significantly lower than the 300 (.32) 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 300 doesn’t offer active grille shutters.

Passenger Space

The 3 Series Sedan has .1 inches more front headroom and .2 inches more front legroom than the 300.

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 300’s liftover is 30.1 inches.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 3 Series offers cargo security. The 300’s non-lockable folding seat and non-lockable remote release defeat cargo security.

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 300 doesn’t offer a power trunk.

Ergonomics

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 300 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 300’s rear power window switches have to be held the entire time to open or close them fully.

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 300 can only close 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 300’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 300’s headlights are rated “Poor.”

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 300 doesn’t offer an automated parking system.

Model Availability

The BMW 3 Series comes in sedan, four door hatchback and station wagon bodystyles; the Chrysler 300 isn’t available as a four door hatchback or station wagon.
