Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Mercedes C-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW 4 Series Gran Coupe doesn’t offer pretensioners for the rear seat belts.

The C-Class Sedan’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 Gran Coupe doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Mercedes C-Class Sedan 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.

The C-Class Sedan’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 Gran Coupe doesn’t offer a driver alert monitor.

Both the C-Class Sedan and the 4 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all-wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the C-Class Sedan the rating of “Top Pick” for 2017, a rating granted to only 107 vehicles tested by the IIHS. The 4 Series Gran Coupe has not been tested, yet.

Car and Driver

Suspension and Handling Comparison

The C-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The C-Class Sedan’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The 4 Series Gran Coupe doesn’t offer a load leveling suspension.

The C-Class Sedan’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 Gran Coupe doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the C-Class Sedan’s wheelbase is 1.2 inches longer than on the 4 Series Gran Coupe (111.8 inches vs. 110.6 inches).

For better handling and stability, the track (width between the wheels) on the C-Class Sedan is 1.7 inches wider in the front than on the 4 Series Gran Coupe.

The AMG C43 Sedan 4MATIC handles at .93 G’s, while the 430i Gran Coupe pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

The Mercedes C-Class Sedan may be more efficient, handle and accelerate better because it weighs about 150 to 250 pounds less than the BMW 4 Series Gran Coupe.

The front grille of the C-Class 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 4 Series Gran Coupe doesn’t offer active grille shutters.

The C-Class Sedan has standard seating for 5 passengers; the 4 Series Gran Coupe can only carry 2.

The C-Class Sedan has .2 inches more rear headroom and 1.5 inches more rear legroom than the 4 Series Gran Coupe.

Cargo Capacity Comparison

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the C-Class offers cargo security. The 4 Series Gran Coupe’s hatchback body style defeats cargo security.

Ergonomics Comparison

The C-Class Sedan 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 Gran Coupe doesn’t offer a remote starting system.

Unlike the driver-only memory system in the 4 Series Gran Coupe, the C-Class Sedan 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 Sedan’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 Gran Coupe doesn’t offer an easy entry system.

Optional air conditioned seats in the C-Class Sedan 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 Comparison
