Safety Comparison

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 A4 doesn’t offer pre-crash pretensioners.

The C-Class Sedan’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The A4 doesn’t offer a lane departure warning system.

The C-Class Sedan offers optional Parktronic™ to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The A4 doesn’t offer a front parking aid.

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 A4 doesn’t offer a driver alert monitor.

The C-Class Sedan has standard mbrace, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The A4 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the C-Class Sedan and the A4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Warranty Comparison

There are over 18 percent more Mercedes dealers than there are Audi dealers, which makes it easier should you ever need service under the C-Class Sedan’s warranty.

Reliability Comparison

Tires and Wheels Comparison

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the C-Class Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A4 doesn’t offer run-flat tires.

Suspension and Handling Comparison

The C-Class Sedan has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The A4’s suspension doesn’t offer adjustable shock absorbers.

The C-Class Sedan has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The A4 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 A4 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 A4 (111.8 inches vs. 110.6 inches).

The C400 Sedan 4MATIC handles at .88 G’s, while the A4 2.0T Quattro pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The C400 Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the A4 2.0T Quattro (25.9 seconds @ .8 average G’s vs. 27.6 seconds @ .62 average G’s).

For better maneuverability, the C-Class Sedan’s turning circle is .9 feet tighter than the A4’s (36.8 feet vs. 37.7 feet).

Chassis Comparison

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 A4 doesn’t offer active grille shutters.

Cargo Capacity Comparison

The C-Class Sedan has a larger trunk than the A4 with its rear seat up (12.8 vs. 12.4 cubic feet).

To make loading and unloading groceries and cargo easier, especially for short adults or children, the C-Class Sedan offers an optional power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The A4 doesn’t offer a power trunk.

Ergonomics Comparison

Unlike the driver-only memory seat and mirrors optional at extra cost in the A4, 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 A4 doesn’t offer an easy entry system.

The C-Class Sedan offers an optional heads-up display which projects speed and navigation instruction readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The A4 doesn’t offer a heads-up display.

If the windows are left down on the C-Class Sedan the driver can raise them all using the key in the outside lock cylinder or the keyless remote; on a hot day the driver can lower the windows. The driver of the A4 can’t use the remote to operate the windows.

While driving with high beams on, sensitive light sensors available for the C-Class Sedan detect other vehicles which could be blinded and automatically switch to low beams. The A4 doesn’t offer automatic dimming high beams.

When the C-Class Sedan is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The A4’s mirror doesn’t automatically adjust for backing.

The C-Class Sedan’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The A4 doesn’t offer air conditioned front seats.

The C-Class Sedan has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the A4.

Optional Mercedes-Benz Apps for the C-Class Sedan allows the driver and passengers access to select programs on their smartphones, including finding fuel prices at nearby service stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The A4 doesn’t offer factory integrated smartphone program access.

The C-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The A4 doesn’t offer an automated parking system.

Recommendations Comparison

Both the Mercedes C-Class Sedan and Audi A4 won an award in Kiplinger’s 2015 car issue.

The C-Class Sedan was chosen as one of Automobile Magazine’s “All Stars” in 2015. The A4 has never been an “All Star.”
