Mercedes-Benz B-Class Electric Drive data analysis

How Mercedes-Benz B-Class Electric Drive combined fuel economy varies

Across 3 configurations recorded for the 2015 through 2017 Mercedes-Benz B-Class Electric Drive, combined fuel economy runs from 84 MPG to 84 MPG. The strongest figure belongs to the 2015 Mercedes-Benz B-Class Electric Drive (Auto (A1)) at 84 MPG, and the weakest to the 2017 car (Auto (A1)) at 84 MPG — a spread of 0%. The narrow spread means any year of the Mercedes-Benz B-Class Electric Drive in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

What changed for 2017

Average combined fuel economy for the 2017 Mercedes-Benz B-Class Electric Drive is 84 MPG, against 84 MPG for the 2016 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.

How to read this Mercedes-Benz B-Class Electric Drive data

This page lists every 2015 through 2017 Mercedes-Benz B-Class Electric Drive record we hold for this measurement — 3 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.

Where these Mercedes-Benz B-Class Electric Drive figures come from

Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The Mercedes-Benz B-Class Electric Drive record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.

Our Real-World Speed MPG Adjuster re-scales the Mercedes-Benz B-Class Electric Drive EPA highway result with a quadratic drag term (mpg = hwy ÷ (1 + k·(v² − 60²)/60²), k = 0.55 for trucks, SUVs and vans, 0.42 for cars). Wind, roof racks, and a heavy right foot make it worse, never better.
