BMW 4 Series data analysis

How BMW 4 Series combined fuel economy varies

Across 133 configurations recorded for the 2015 through 2027 BMW 4 Series, combined fuel economy runs from 21 MPG to 31 MPG. The strongest figure belongs to the 2025 BMW 4 Series (Auto (S8), 4 cyl, 2.0 L) at 31 MPG, and the weakest to the 2020 car (Man 6-spd, 6 cyl, 3.0 L) at 21 MPG — a spread of 48%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the BMW 4 Series would be misleading.

What changed for 2027

Average combined fuel economy for the 2027 BMW 4 Series is 29.4 MPG, against 29.1 MPG for the 2026 car — it rose by 0.3 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 BMW 4 Series data

This page lists every 2015 through 2027 BMW 4 Series record we hold for this measurement — 133 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 BMW 4 Series numbers

The 2015 through 2027 BMW 4 Series entries here cover the variants Auto (S8), 4 cyl, 2.0 L, Auto (S8), 6 cyl, 3.0 L, Auto (S8), 4 cyl, 3.0 L, Man 6-spd, 4 cyl, 2.0 L and Man 6-spd, 6 cyl, 3.0 L. 2015 is the busiest model year in the record with 14 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 BMW 4 Series 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 BMW 4 Series 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 BMW 4 Series 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.

Frequently Asked Questions About 4 Series MPG
