Compare the2023 Mercedes AMG C-Class CoupeVS 2023 BMW M4

For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG 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 M4 doesn’t offer pretensioners for its rear seat belts.

Using vehicle speed sensors, smart airbags in the AMG C-Class Coupe deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The AMG C-Class Coupe’s side airbags will shut off if a child is leaning against the door. The M4’s side airbags don’t have smart features and will always deploy full force.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG C-Class Coupe. But it costs extra on the M4.

Both the AMG C-Class Coupe and the M4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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 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 AMG C-Class Coupe’s warranty.

On the EPA test cycle the AMG C-Class Coupe gets better mileage than the M4 Coupe:

The AMG C-Class Coupe has 1.8 gallons more fuel capacity than the M4 (17.4 vs. 15.6 gallons), for longer range between fill-ups.

The Mercedes AMG C-Class Coupe comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the M4.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the AMG 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. The M4 doesn’t offer run-flat tires.

The AMG 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 M4 doesn’t offer drift compensation steering.

For better maneuverability, the AMG C 43 Coupe’s turning circle is 1.6 feet tighter than the M4’s (38.4 feet vs. 40 feet).

The AMG C-Class Coupe is 3.9 inches shorter than the M4, making the AMG C-Class Coupe easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the AMG C-Class Coupe 63 S has an electronically controlled liquid-filled front engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The M4 uses conventional solid rubber engine mounts.

The design of the Mercedes AMG C-Class Coupe amounts to more than styling. The AMG C-Class Coupe has an aerodynamic coefficient of drag of .3 Cd. That is significantly lower than the M4 (.34). A more efficient exterior helps the AMG C-Class Coupe go faster and keeps the interior quieter. It also helps the AMG C-Class Coupe get better fuel mileage.

The AMG C-Class Coupe has .3 inches more front legroom, 1.8 inches more rear headroom and .7 inches more rear shoulder room than the M4 Coupe.

The AMG C-Class Coupe’s standard folding rear seats are split to accommodate bulky cargo. The M4 Convertible’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Unlike the driver-only memory system in the M4, the AMG C-Class Coupe has standard driver and 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 AMG 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 M4 doesn’t offer an easy entry system.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG C-Class Coupe has standard extendable sun visors. The M4 doesn’t offer extendable visors.

The AMG C-Class Coupe has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The M4 doesn’t offer a rear seat center armrest.

The Mercedes AMG C-Class comes in coupe, convertible and sedan bodystyles; the BMW M4 isn’t available as a sedan.
