Across 2 configurations recorded for the 2027 Audi S6 e-tron, combined fuel economy runs from 100 MPG to 103 MPG. The strongest figure belongs to the 2027 Audi S6 e-tron (Auto (A1)) at 103 MPG, and the weakest to the 2027 car (Auto (A1)) at 100 MPG — a spread of 3%.

How to read this Audi S6 e-tron data
This page lists every 2027 Audi S6 e-tron record we hold for this measurement — 2 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 Audi S6 e-tron 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 Audi S6 e-tron 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.
