Where These Numbers Come From

This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 76 ratings for the Mercedes-Benz GLC-Class from 2016 to 2027. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Electric versions are rated in MPGe, the EPA's miles-per-gallon equivalent, and the table also shows their official range. Plug-in hybrid figures in the table are the gas-only ratings, since those are the ones you can compare with a regular car. When the EPA posts an updated file with new model years or corrected ratings, this page is rebuilt from it. The cost calculator uses the gas or electricity price you enter rather than a national average, so the result fits where you live.

Ratings on this page come from the EPA file downloaded on October 1, 2026.
