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 and force limiters to limit the pressure the belts will exert on the passengers. The Chrysler 300 doesn’t offer pretensioners for its 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 300 doesn’t offer pre-crash pretensioners.

The C-Class Sedan has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 300 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The C-Class Sedan offers an optional Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 300 doesn’t offer backup collision prevention brakes.

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 300 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The C-Class Sedan has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the 300 S/Touring L offers a blind spot warning system.

Both the C-Class Sedan and 300 offer rear cross-traffic warning, but the C-Class Sedan with Rear Cross-Traffic Alert also has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The 300’s Rear Cross Path Detection doesn’t automatically brake.

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 300 doesn’t offer a driver alert monitor.

Both the C-Class Sedan and the 300 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 and available all wheel drive.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Mercedes C-Class Sedan is safer than the 300:

	C-Class Sedan	300
Overall Evaluation	GOOD	MARGINAL
Restraints	GOOD	GOOD
Head Neck Evaluation	GOOD	GOOD
Peak Head Forces	0 G’s	0 G’s
Steering Column Movement Rearward	1 cm	9 cm
Chest Evaluation	GOOD	GOOD
Max Chest Compression	27 cm	28 cm
Hip & Thigh Evaluation	GOOD	GOOD
Femur Force R/L	.5/.4 kN	3.7/3 kN
Hip & Thigh Injury Risk R/L	0%/0%	1%/0%
Lower Leg Evaluation	GOOD	POOR
Tibia index R/L	.3/.47	1.21/.58
Tibia forces R/L	1.9/1.7 kN	3/4.7 kN

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the C-Class Sedan its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 126 vehicles tested by the IIHS. The 300 is not even a standard “Top Safety Pick.”

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 300’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Reliability

For smoother operation, better efficiency and fewer moving parts, the C-Class Sedan has an overhead cam design, rather than the old pushrod design of some of the engines in the 300.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Chrysler vehicles. With 76 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Chrysler.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Chrysler With 45 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Chrysler.

Engine

The C-Class Sedan’s 2.0 turbo 4-cylinder hybrid produces 35 lbs.-ft. more torque (295 vs. 260) than the 300’s standard 3.6 DOHC V6. The C-Class Sedan’s 2.0 turbo 4-cylinder hybrid produces 31 lbs.-ft. more torque (295 vs. 264) than the 300S’ standard 3.6 DOHC V6.

As tested in Consumer Reports the Mercedes C-Class Sedan is faster than the Chrysler 300 V6:

	C-Class Sedan	300
Zero to 30 MPH	2.8 sec	3.2 sec
Zero to 60 MPH	6.7 sec	7.4 sec
45 to 65 MPH Passing	4.3 sec	4.6 sec
Quarter Mile	15.2 sec	15.8 sec
Speed in 1/4 Mile	96 MPH	94.8 MPH

Fuel Economy and Range

On the EPA test cycle the C-Class Sedan gets better mileage than the 300:

			MPG
C-Class Sedan
	RWD	2.0 turbo 4-cyl.	25 city/36 hwy
	AWD	2.0 turbo 4-cyl.	24 city/33 hwy
300
	RWD	3.6 DOHC V6	19 city/30 hwy
		5.7 OHV V8	16 city/25 hwy
	AWD	3.6 DOHC V6	18 city/27 hwy

Regenerative brakes improve the C-Class Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The 300 doesn’t offer a regenerative braking system.

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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The 300 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 (7 out of 10) than the Chrysler 300 (3). This means the C-Class Sedan produces up to 24.5 pounds less smog-producing pollutants than the 300 every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Mercedes C-Class Sedan, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 300.

Brakes and Stopping

For better stopping power the C-Class Sedan’s standard front brake rotors are larger than those on the 300:

	C-Class Sedan	300
Front Rotors	13 inches	12.6 inches

The C-Class Sedan’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the 300 are solid, not vented.

Tires and Wheels

For better traction, the C-Class Sedan has larger standard tires than the 300 (F:225/45R18 & R:245/40R18 vs. 215/65R17).

The C-Class Sedan’s standard 225/45R18 front and 245/40R18 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the 300 Touring’s standard 65 series tires. The C-Class Sedan’s optional 225/40R19 front and 255/35R19 rear tires have a lower 40 series front and 35 series rear profile than the 300’s optional 45 series tires.

For better ride, handling and brake cooling the C-Class Sedan has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 300 Touring.

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 300 doesn’t offer run-flat tires.

Suspension and Handling

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 300 doesn’t offer drift compensation steering.

Chassis

The C-Class Sedan is 11.6 inches shorter than the 300, making the C-Class Sedan easier to handle, maneuver and park in tight spaces.

The design of the Mercedes C-Class Sedan amounts to more than styling. The C-Class Sedan has an aerodynamic coefficient of drag of .24 Cd. That is significantly lower than the 300 (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the C-Class Sedan get better fuel mileage.

Passenger Space

The C-Class Sedan has 1.9 inches more front hip room and 2 inches more rear hip room than the 300.

Cargo Capacity

Pressing a switch automatically lowers the C-Class Sedan’s rear seats, to make changing between passengers and cargo easier. The 300 doesn’t offer automatic folding seats.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the C-Class offers cargo security. The 300’s non-lockable folding seat and non-lockable remote release defeat cargo security.

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 300 doesn’t offer a power or hands-free opening trunk.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the 300 S/Touring L, the C-Class Sedan 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 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. An easy entry system costs extra on the 300, and is not available on all models.

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 300 doesn’t offer a heads-up display.

The C-Class Sedan’s power parking brake sets with one touch and releases with one touch or automatically. The 300’s parking brake has to be released manually.

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

If the windows are left open on the C-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the 300 can only close 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 300’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The C-Class Sedan’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the 300’s standard projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen. The C-Class Sedan’s LED headlights produce a white, bright light using less electricity than the 300’s optional xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

Consumer Reports rated the C-Class Sedan’s headlight performance “Excellent,” a higher rating than the 300’s headlights, which were rated “Poor” to “Good” (depending on model and options).

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The C-Class Sedan’s headlights were rated “Good” to “Acceptable” by the IIHS, while the 300’s headlights are rated “Poor.”

A power rear sunshade and manual rear side window sunshades are standard in the C-Class Sedan to help block heat and glare for the rear passengers. The 300 doesn’t offer rear side window sunshades.

The C-Class Sedan has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The 300 doesn’t offer a house-current electrical outlet.

The C-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, stopping and changing direction automatically. The 300 doesn’t offer an automated parking system.

Model Availability

The Mercedes C-Class comes in coupe, convertible and sedan bodystyles; the Chrysler 300 isn’t available as a coupe or convertible.

Recommendations

The Mercedes C-Class outsold the Chrysler 300 by 86% during 2022.
