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 Genesis G70 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 G70 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 G70 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 G70 doesn’t offer automatic braking for stationary objects directly to the rear.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The C-Class Sedan offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The G70 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the C-Class Sedan and the G70 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, front seat center airbag, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.

The Mercedes C-Class Sedan achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The G70 has not yet been fully evaluated by the IIHS for 2024.

Warranty

There are over 59 percent more Mercedes dealers than there are Genesis dealers, which makes it much easier should you ever need service under the C-Class Sedan’s warranty.

Fuel Economy and Range

On the EPA test cycle the C-Class Sedan gets better mileage than the G70:

			MPG
C-Class Sedan
	RWD	2.0 turbo 4-cyl.	25 city/35 hwy
	AWD	2.0 turbo 4-cyl.	24 city/33 hwy
G70
	RWD	2.5 turbo 4-cyl.	21 city/29 hwy
		3.3 turbo V6	17 city/25 hwy
	AWD	2.5 turbo 4-cyl.	20 city/28 hwy
		3.3 turbo V6	17 city/23 hwy

Regenerative brakes improve the C-Class Sedan’s fuel efficiency by converting inertia back into energy instead of wasting it. The G70 doesn’t offer a regenerative braking system.

The C-Class Sedan has 1.6 gallons more fuel capacity than the G70 (17.4 vs. 15.8 gallons), for longer range between fill-ups.

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 Genesis G70 (4 to 5). This means the C-Class Sedan produces up to 13.2 pounds less smog-producing pollutants than the G70 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 G70.

Tires and Wheels

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 G70 doesn’t offer run-flat tires.

Suspension and Handling

The C-Class Sedan has standard front and rear gas-charged shocks for better control over choppy roads. The G70’s suspension doesn’t offer rear gas-charged shocks.

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 G70 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 G70 (112.8 inches vs. 111.6 inches).

Chassis

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 G70 (.28) 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 .2 inches more front headroom, 1.2 inches more rear legroom and 1 inch more rear shoulder room than the G70.

Cargo Capacity

Pressing a switch automatically lowers the C-Class Sedan’s rear seats, to make changing between passengers and cargo easier. The G70 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 G70’s non-lockable folding seat and non-lockable remote release defeat cargo security.

Ergonomics

Unlike the driver-only memory system in the G70 Advanced/Sport Prestige, 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 Keyless-Go allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Proximity Key standard on the G70 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

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 G70’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are optional on the C-Class Sedan to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The G70 doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the C-Class Sedan’s headlight performance “Excellent,” a higher rating than the G70’s headlights, which were rated “Good.”

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 G70 doesn’t offer a rear or rear side window sunshades.

The Mercedes C-Class Sedan has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the G70 Advanced/Sport Prestige.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes C-Class has a standard wireless phone charging system (Qi) in the center console. Only the G70 Advanced/Sport Prestige offers wireless charging.

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 G70 doesn’t offer a house-current electrical outlet.

The C-Class Sedan’s Active Parking Assist can parallel park or back into a parking spot by itself, stopping and changing direction automatically. The G70 doesn’t offer an automated parking system.

Recommendations

The Mercedes C-Class outsold the Genesis G70 by over two to one during 2023.
