Safety

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 Nissan Maxima 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 Maxima doesn’t offer pre-crash pretensioners.

The C-Class Sedan offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Maxima doesn’t offer all-wheel drive.

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 Maxima doesn’t offer a lane departure warning system.

Both the C-Class Sedan and the Maxima have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The C-Class Sedan comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Maxima’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Engine

The C 300 Sedan’s standard 2.0 turbo 4 cyl. produces 12 lbs.-ft. more torque (273 vs. 261) than the Maxima’s 3.5 DOHC V6. The AMG C 43 Sedan’s standard 3.0 turbo V6 produces 85 more horsepower (385 vs. 300) and 123 lbs.-ft. more torque (384 vs. 261) than the Maxima’s 3.5 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the C 300 Sedan RWD gets better fuel mileage than the Maxima (23 city/34 hwy vs. 21 city/30 hwy).

In heavy traffic or at stoplights the C-Class Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Maxima doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes C-Class Sedan higher (5 out of 10) than the Nissan Maxima (3). This means the C-Class Sedan produces up to 16.5 pounds less smog-producing pollutants than the Maxima every 15,000 miles.

Brakes and Stopping

For better stopping power the C-Class Sedan’s front brake rotors are larger than those on the Maxima:

Tires and Wheels

The C-Class Sedan’s optional 255/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Maxima 3.5 SR’s 40 series tires.

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 Maxima doesn’t offer run-flat tires.

Suspension and Handling

The C-Class Sedan offers an available 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 Maxima’s suspension doesn’t offer adjustable shock absorbers.

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 Maxima doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the C-Class Sedan’s wheelbase is 2.5 inches longer than on the Maxima (111.8 inches vs. 109.3 inches).

The C-Class Sedan’s front to rear weight distribution is more even (53% to 47%) than the Maxima’s (60.8% to 39.2%). This gives the C-Class Sedan more stable handling and braking.

The C 300 Sedan handles at .91 G’s, while the Maxima Platinum pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The C 300 Sedan executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Maxima Platinum (25.7 seconds @ .71 average G’s vs. 27 seconds @ .67 average G’s).

For better maneuverability, the C-Class Sedan’s turning circle is 1.3 feet tighter than the Maxima’s (36.8 feet vs. 38.1 feet).

Chassis

The C-Class Sedan is 8.3 inches shorter than the Maxima, making the C-Class Sedan easier to handle, maneuver and park in tight spaces.

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 Maxima doesn’t offer active grille shutters.

Passenger Space

The C-Class Sedan has .4 inches more rear headroom and 1 inch more rear legroom than the Maxima.

Cargo Capacity

To make loading and unloading groceries and cargo easier when your hands are full, the C-Class Sedan’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Maxima doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The engine in the C-Class Sedan is mounted longitudinally (North-South), instead of sideways, as in the Maxima. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Nissan. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 44% lower rating, Nissan is ranked 20th.

Ergonomics

Unlike the driver-only memory system in the Maxima Platinum, 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 offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Maxima doesn’t offer a heads-up display.

The power windows standard on both the C-Class Sedan and the Maxima have locks to prevent small children from operating them. When the lock on the C-Class Sedan is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Maxima prevents the driver from operating the other windows just as it does the other passengers.

The C-Class Sedan’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Maxima’s rear power window switches have to be held the entire time to open or close them fully.

The C-Class Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Maxima’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 Maxima doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the C-Class Sedan offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Maxima doesn’t offer cornering lights.

The C-Class Sedan’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Maxima SV/SL/SR/Platinum.

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 Maxima doesn’t offer an automated parking system.

Model Availability

The Mercedes C-Class comes in coupe, convertible and sedan bodystyles; the Nissan Maxima isn’t available as a coupe or convertible.

Economic Advantages

According to The Car Book by Jack Gillis, the C-Class Sedan is less expensive to operate than the Maxima because typical repairs cost much less on the C-Class Sedan than the Maxima, including $71 less for fuel injection and $481 less for a timing belt/chain.

Recommendations

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

The Mercedes C-Class outsold the Nissan Maxima by 22% during the 2018 model year.
