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 its rear seat belts.

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, driver alert monitors, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.

There are over 9 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.

The C-Class Coupe has 1.8 gallons more fuel capacity than the 4 Series Coupe (17.4 vs. 15.6 gallons), for longer range between fill-ups.

A nine-speed automatic is standard on the Mercedes C-Class Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 4 Series Coupe.

For better traction and acceleration, the C-Class Coupe has larger standard 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’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 .6 feet tighter than the 4 Series Coupe’s (36.8 feet vs. 37.4 feet). The C 300 4MATIC’s turning circle is 1.8 feet tighter than the 4 Series Coupe xDrive’s (37.6 feet vs. 39.4 feet).

Standard Trailer Stabilization Program on the C-Class Coupe uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The 4 Series Coupe doesn’t offer electronic trailer sway control.

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.
