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 Hyundai Azera 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 Azera doesn’t offer pre-crash pretensioners.

The C-Class Sedan has a standard Collision Prevention Assist Plus, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Azera has a collision warning system without the crash-mitigating brake feature that could reduce stopping distances.

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

The C-Class Sedan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Azera only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

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 Azera doesn’t offer a driver alert monitor.

Compared to metal, the C-Class Sedan’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Hyundai Azera has a metal gas tank.

Both the C-Class Sedan and the Azera have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems and blind spot warning systems.

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 Azera has not been fully tested, yet, but doesn’t qualify for 2017 “Top Pick.”

Reliability Comparison

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Hyundai vehicles. J.D. Power ranks Mercedes 12th in reliability, above the industry average. With 23 more problems per 100 vehicles, Hyundai is ranked 19th.

Engine Comparison

The C300 Sedan’s standard 2.0 turbo 4 cyl. produces 18 lbs.-ft. more torque (273 vs. 255) than the Azera’s 3.3 DOHC V6. The AMG C43 Sedan’s standard 3.0 turbo V6 produces 69 more horsepower (362 vs. 293) and 129 lbs.-ft. more torque (384 vs. 255) than the Azera’s 3.3 DOHC V6.

As tested in Motor Trend the C300 Sedan 2.0 turbo 4 cyl. is faster than the Hyundai Azera:

Fuel Economy and Range Comparison

On the EPA test cycle the C300 Sedan RWD gets better fuel mileage than the Azera (24 city/34 hwy vs. 20 city/28 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 Azera doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

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

Tires and Wheels Comparison

The C-Class Sedan’s optional 245/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Azera Limited’s optional 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 Azera doesn’t offer run-flat tires.

Suspension and Handling Comparison

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 Azera’s suspension doesn’t offer adjustable shock absorbers.

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 Azera 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 Azera doesn’t offer drift compensation steering.

The C-Class Sedan’s front to rear weight distribution is more even (55% to 45%) than the Azera’s (59% to 41%). This gives the C-Class Sedan more stable handling and braking.

The AMG C43 Sedan 4MATIC handles at .93 G’s, while the Azera pulls only .80 G’s of cornering force in a Car and Driver skidpad test.

The C300 Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Azera (26.3 seconds @ .7 average G’s vs. 27.9 seconds @ .62 average G’s).

Chassis Comparison

The Mercedes C-Class Sedan may be more efficient, handle and accelerate better because it weighs about 100 to 250 pounds less than the Hyundai Azera.

The C-Class Sedan is 9.2 inches shorter than the Azera, 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 Azera doesn’t offer active grille shutters.

Cargo Capacity Comparison

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 just by kicking your foot under the back bumper, completely leaving your hands free. The Azera doesn’t offer a power trunk.

Ergonomics Comparison

Unlike the driver-only memory system in the Azera, 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 Azera doesn’t offer a heads-up display.

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 Azera’s rear power window switches have to be held the entire time to open or close them fully.

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 Azera can only operate the windows from inside the vehicle, with the ignition on.

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 Azera’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 Azera doesn’t offer cornering lights.

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 Azera’s mirror doesn’t automatically adjust for backing.

The C-Class Sedan has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Azera has an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold Winter days, the C-Class Sedan 300’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Azera doesn’t offer a heated steering wheel.

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 Azera doesn’t offer an automated parking system.

Recommendations Comparison

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

The Mercedes C-Class outsold the Hyundai Azera by almost seventeen to one during the 2016 model year.
