Bugatti Chiron data analysis

How Bugatti Chiron combined fuel economy varies

Across 10 configurations recorded for the 2018 through 2024 Bugatti Chiron, combined fuel economy runs from 9 MPG to 11 MPG. The strongest figure belongs to the 2018 Bugatti Chiron (Auto (AM-S7), 16 cyl, 8.0 L) at 11 MPG, and the weakest to the 2024 car (Auto (AM-S7), 16 cyl, 8.0 L) at 9 MPG — a spread of 22%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Bugatti Chiron would be misleading.

What changed for 2024

Average combined fuel economy for the 2024 Bugatti Chiron is 9 MPG, against 10 MPG for the 2023 car — it fell by 1 MPG. Buyers who care most about this figure should look at the earlier model years in the table above before assuming newest is best.

How to read this Bugatti Chiron data

This page lists every 2018 through 2024 Bugatti Chiron record we hold for this measurement — 10 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 Bugatti Chiron numbers

The 2018 through 2024 Bugatti Chiron entries here span 7 model years of published measurements for this figure. 2023 is the busiest model year in the record with 2 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 Bugatti Chiron 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 Bugatti Chiron 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 Bugatti Chiron 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.
