Mercedes-Benz CLE-Class data analysis

How Mercedes-Benz CLE-Class combined fuel economy varies

Across 23 configurations recorded for the 2024 through 2027 Mercedes-Benz CLE-Class, combined fuel economy runs from 22 MPG to 28 MPG. The strongest figure belongs to the 2024 Mercedes-Benz CLE-Class (Auto 9-spd, 4 cyl, 2.0 L) at 28 MPG, and the weakest to the 2027 car (Auto 9-spd, 6 cyl, 3.0 L) at 22 MPG — a spread of 27%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Mercedes-Benz CLE-Class would be misleading.

What changed for 2027

Average combined fuel economy for the 2027 Mercedes-Benz CLE-Class is 25.2 MPG, against 25 MPG for the 2026 car — it rose by 0.2 MPG. That is a real improvement, and it is the kind of change worth paying the newer-year premium for if this figure drives your decision.

How to read this Mercedes-Benz CLE-Class data

This page lists every 2024 through 2027 Mercedes-Benz CLE-Class record we hold for this measurement — 23 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.

Configurations behind these Mercedes-Benz CLE-Class numbers

The 2024 through 2027 Mercedes-Benz CLE-Class entries here cover the variants Auto 9-spd, 4 cyl, 2.0 L and Auto 9-spd, 6 cyl, 3.0 L. 2027 is the busiest model year in the record with 6 separate measured configurations, which is why a single quoted combined fuel economy figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.

Where these Mercedes-Benz CLE-Class 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 CLE-Class 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 CLE-Class 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.
