Most and least efficient
Among the Mercedes-Benz models here, the G-Class is the most economical on average at about 13 MPG, while the CLA-Class is the thirstiest at about 27 MPG. The gap between them shows how much the model and body style — not the brand alone — decide your fuel bill.
Fuel types in the lineup
Mercedes-Benz models in this dataset run on diesel and gasoline and hybrid and plug-in hybrid. Choosing a hybrid or electric version cuts the fuel line of the budget the most, especially in city driving, while a conventional gasoline model usually costs less to buy in the first place. Use the comparison tool to set the trade-off against a rival in the same class.
Coverage and method
This Mercedes-Benz section covers 14 models over 64 model-years, drawn from the U.S. EPA's fuel economy files and NHTSA crash-test data. Every figure is an official estimate, so use it to compare vehicles and spot the outliers rather than as a promise of what you will get at the pump. Where a model changed engines, transmissions or body styles between years, the year-by-year pages show the difference.
Pick a model for its year-by-year fuel economy and specs, or open the comparison tool to line any two up side by side. ← All makes
