Honda Accord vs Mercedes-Benz C-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Honda Accord burns about $1,300 of fuel annually against $2,550 for the Mercedes-Benz C-Class. That $1,250 yearly gap compounds to roughly $6,250 over five years and $10,000 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the Honda Accord leads in both cycles — 51 mpg city and 48 mpg highway against 28 and 36 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Honda Accord is recorded with 4 distinct engine configurations (SIDI, SIDI; Hybrid, Hybrid), the Mercedes-Benz C-Class with 4 (SIDI; Mild Hybrid, SIDI & PFI, SIDI; PHEV). Across 64 recorded Honda Accord configurations and 123 for the Mercedes-Benz C-Class, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Honda Accord is offered with Front-Wheel Drive, the Mercedes-Benz C-Class with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Large Cars and Subcompact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Honda Accord emits 183 g/mile of CO2 versus 215 g/mile for the Mercedes-Benz C-Class. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
