For enhanced safety, the front and rear seat shoulder belts of the Mercedes C-Class Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 4 Series Coupe doesn’t offer pretensioners for the rear seat belts.
The C-Class Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 4 Series Coupe doesn’t offer pre-crash pretensioners.
The C-Class Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 4 Series Coupe doesn’t offer a driver alert monitor.
Both the C-Class Coupe and the 4 Series Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.
There are over 10 percent more Mercedes dealers than there are BMW dealers, which makes it easier should you ever need service under the C-Class Coupe’s warranty.
J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Mercedes 12th in initial quality. With 8 more problems per 100 vehicles, BMW is ranked 20th.
The C-Class Coupe’s 2.0 turbo 4-cylinder produces 7 more horsepower (255 vs. 248) and 15 lbs.-ft. more torque (273 vs. 258) than the 430i Coupe’s standard 2.0 turbo 4-cylinder.
The C-Class Coupe has 1.6 gallons more fuel capacity than the 4 Series Coupe (17.4 vs. 15.8 gallons), for longer range between fill-ups.

4 Series Coupe
For better traction and acceleration, the C-Class Coupe has larger rear tires than the 4 Series Coupe (245/40R18 vs. 225/45R18).
The C-Class Coupe’s standard 245/40R18 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 4 Series Coupe’s standard 45 series tires.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the C-Class Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. Run-flat tires aren’t available on some tire packages on the 4 Series Coupe.
The C-Class Coupe 300 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 4 Series Coupe; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the 4 Series Coupe don’t have a run-flat feature, either.
The C-Class Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The 4 Series Coupe doesn’t offer drift compensation steering.

For better maneuverability, the C 300’s turning circle is .3 feet tighter than the 4 Series Coupe’s (36.8 feet vs. 37.1 feet). The C 300’s turning circle is 1.9 feet tighter than the 4 Series Coupe xDrive’s (36.8 feet vs. 38.7 feet).
With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the C-Class offers cargo security. The 4 Series Coupe’s non-lockable folding seat defeats cargo security.
To make loading and unloading groceries and cargo easier, especially for short adults, the C-Class Coupe has a standard power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The 4 Series Coupe doesn’t offer a power trunk, so its trunk has to be closed manually.
J.D. Power and Associates surveys of service recipients show that Mercedes service is better than BMW. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 23% lower rating, BMW is ranked 11th.
The C-Class Coupe has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 4 Series Coupe doesn’t offer a remote starting system.
Unlike the driver-only memory system in the 4 Series Coupe, the C-Class Coupe offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
The C-Class Coupe’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The 4 Series Coupe doesn’t offer an easy entry system.
The C-Class Coupe’s power parking brake sets with one touch and releases with one touch or automatically. The 4 Series Coupe has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the C-Class Coupe has standard extendable sun visors. The 4 Series Coupe doesn’t offer extendable visors.
Optional air-conditioned seats in the C-Class Coupe keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The 4 Series Coupe doesn’t offer air-conditioned seats.
The C-Class Coupe’s optional Active Parking Assist can parallel park or back into a parking spot by itself, stopping and changing direction automatically. The 4 Series Coupe’s automatic parking system requires operating the brakes and transmission to safely park.
