For enhanced safety, the front seat shoulder belts of the Chrysler 300 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 4 Series Gran Coupe doesn’t offer height-adjustable seat belts.

To help make backing safer, the 300 (except Touring)’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 4 Series Gran Coupe doesn’t offer a cross-path warning system.

Both the 300 and the 4 Series Gran Coupe 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, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear parking sensors.


Chrysler’s powertrain warranty covers the 300 1 year and 10,000 miles longer than BMW covers the 4 Series Gran Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 4 Series Gran Coupe ends after only 4 years or 50,000 miles.

There are almost 7 times as many Chrysler dealers as there are BMW dealers, which makes it much easier should you ever need service under the 300’s warranty.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the 300 V8’s fuel efficiency. The 4 Series Gran Coupe doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Chrysler 300 uses regular unleaded gasoline (mid-grade octane recommended with the 5.7 V8 engine for maximum performance). The 4 Series Gran Coupe requires premium, which can cost 5 to 40 cents more per gallon.

The 300 has 2.7 gallons more fuel capacity than the 4 Series Gran Coupe (18.5 vs. 15.8 gallons), for longer range between fill-ups.

The 300 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 4 Series Gran Coupe doesn’t offer a cap-less fueling system.

Brakes and Stopping

Tires and Wheels

For better traction, the 300S/300C/Limited’s tires are larger than the largest tires available on the 4 Series Gran Coupe (245/45R20 vs. 225/45R18).

For better ride, handling and brake cooling the 300S/300C/Limited has standard 20-inch wheels. The 4 Series Gran Coupe’s largest wheels are only 19-inches.

Suspension and Handling

For a smoother ride and more stable handling, the 300’s wheelbase is 9.6 inches longer than on the 4 Series Gran Coupe (120.2 inches vs. 110.6 inches).

For better handling and stability, the track (width between the wheels) on the 300 is 2.6 inches wider in the front and 1.1 inches wider in the rear than on the 4 Series Gran Coupe.

Passenger Space

Because it has more passenger and cargo room, the 300 is rated a Large car by the EPA, while the 4 Series Gran Coupe is rated a Compact.

The 300 has standard seating for 5 passengers; the 4 Series Gran Coupe can only carry 2.

The 300 has 14.3 cubic feet more passenger volume than the 4 Series Gran Coupe (106.3 vs. 92).

The 300 has 4.7 inches more front shoulder room, 1 inch more rear headroom, 6.4 inches more rear legroom and 3.4 inches more rear shoulder room than the 4 Series Gran Coupe.


The 300 (except Base)’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The 4 Series Gran Coupe doesn’t offer an easy entry system.

Heated windshield washer nozzles are standard on the 300 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 4 Series Gran Coupe doesn’t offer heated windshield washer nozzles.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the 300 has standard extendable sun visors. The 4 Series Gran Coupe doesn’t offer extendable visors.

Optional air-conditioned seats in the 300 (except Touring/Touring L) keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The 4 Series Gran Coupe doesn’t offer air-conditioned seats.

Economic Advantages

Insurance will cost less for the 300 owner. The Complete Car Cost Guide estimates that insurance for the 300 will cost $1620 less than the 4 Series Gran Coupe over a five-year period.

According to The Car Book by Jack Gillis, the 300 is less expensive to operate than the 4 Series Gran Coupe because it costs $315 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the 300 than the 4 Series Gran Coupe, including $414 less for a water pump, $21 less for front brake pads, $430 less for a starter, $37 less for fuel injection, $135 less for a fuel pump, $250 less for front struts and $328 less for a timing belt/chain.
