Using vehicle speed sensors and seat sensors, smart airbags in the Accord Hybrid deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Accord Hybrid’s side airbags will shut off if a child is leaning against the door. The C 350e’s side airbags don’t have smart features and will always deploy full force.

To help make backing safer, the Accord Hybrid EX/EX-L/Touring’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The C 350e doesn’t offer a cross-path warning system.

Both the Accord Hybrid and the C 350e have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, driver alert monitors, available blind spot warning systems and rear parking sensors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Accord Hybrid the rating of “Top Pick” for 2018, a rating granted to only 85 vehicles tested by the IIHS. The C 350e has not been tested, yet.


Honda’s powertrain warranty covers the Accord Hybrid 1 year and 10,000 miles longer than Mercedes covers the C 350e. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the C 350e ends after only 4 years or 50,000 miles.

There are almost 3 times as many Honda dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Accord Hybrid’s warranty.


J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Honda 12th in reliability, above the industry average. With 7 more problems per 100 vehicles, Mercedes is ranked 15th.

From surveys of all its subscribers, Consumer Reports’ April 2018 Auto Issue reports that Honda vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Honda 5 places higher in reliability than Mercedes.

Fuel Economy and Range

On the EPA test cycle the Accord Hybrid gets better fuel mileage than the C 350e running its gasoline engine (48 city/48 hwy vs. 28 city/32 hwy).

To lower fuel costs and make buying fuel easier, the Honda Accord Hybrid uses regular unleaded gasoline. The C 350e requires premium, which can cost 20 to 55 cents more per gallon.

The Accord Hybrid has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The C 350e doesn’t offer a cap-less fueling system.


The Accord Hybrid has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The C 350e doesn’t offer a CVT.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Accord Hybrid is .5 inches wider in the front and 2.6 inches wider in the rear than on the C 350e.


The Honda Accord Hybrid may be more efficient, handle and accelerate better because it weighs about 500 to 600 pounds less than the Mercedes C 350e.

The front grille of the Accord Hybrid uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The C 350e doesn’t offer active grille shutters.

The Accord Hybrid uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The C 350e doesn’t offer active noise cancellation.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Accord Hybrid a Large car, while the C 350e is rated a Compact.

The Accord Hybrid has 15.6 cubic feet more passenger volume than the C 350e (105.6 vs. 90).

The Accord Hybrid has 2.4 inches more front headroom, .6 inches more front legroom, 3 inches more front shoulder room, .2 inches more rear headroom, 5.2 inches more rear legroom and 1 inch more rear shoulder room than the C 350e.

Cargo Capacity

The Accord Hybrid has a much larger trunk than the C 350e (16.7 vs. 11.8 cubic feet).


To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Accord Hybrid has standard extendable sun visors. The C 350e doesn’t offer extendable visors.

Both the Accord Hybrid and the C 350e offer available heated front seats. The Accord Hybrid Touring also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the C 350e.


The Accord was chosen as one of Car and Driver’s “Top Ten” for 2018 and 22 of the last 24 years. The C 350e has never been a Car and Driver “Top Ten” pick.
