Honda Passport vs Mercedes-Benz GLC-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mercedes-Benz GLC-Class burns about $2,600 of fuel annually against $2,800 for the Honda Passport. That $200 yearly gap compounds to roughly $1,000 over five years and $1,600 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 Mercedes-Benz GLC-Class leads in both cycles — 26 mpg city and 33 mpg highway against 20 and 25 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Honda Passport is recorded with 1 distinct engine configuration (SIDI), the Mercedes-Benz GLC-Class with 3 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 13 recorded Honda Passport configurations and 72 for the Mercedes-Benz GLC-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 Passport is offered with All-Wheel Drive, Front-Wheel Drive, the Mercedes-Benz GLC-Class with Rear-Wheel Drive, All-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 Small Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Mercedes-Benz GLC-Class emits 84 g/mile of CO2 versus 405 g/mile for the Honda Passport. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
