Mercedes-Benz S-Class data analysis

How Mercedes-Benz S-Class estimated annual fuel cost varies

Across 106 configurations recorded for the 2015 through 2027 Mercedes-Benz S-Class, estimated annual fuel cost runs from $2,900 to $5,450. The strongest figure belongs to the 2017 Mercedes-Benz S-Class (Auto 7-spd, 6 cyl, 3.0 L) at $2,900, and the weakest to the 2023 car (Auto 9-spd, 12 cyl, 6.0 L) at $5,450 — a spread of 47%. 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 S-Class would be misleading.

What changed for 2027

Average estimated annual fuel cost for the 2027 Mercedes-Benz S-Class is $4,238, against $3,988 for the 2026 car — it rose by $250. 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 Mercedes-Benz S-Class data

This page lists every 2015 through 2027 Mercedes-Benz S-Class record we hold for this measurement — 106 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 S-Class numbers

The 2015 through 2027 Mercedes-Benz S-Class entries here cover variants including Auto 9-spd, 12 cyl, 6.0 L, Auto 9-spd, 6 cyl, 3.0 L, Auto 9-spd, 8 cyl, 4.0 L, Auto 7-spd, 12 cyl, 6.0 L, Auto 9-spd, 4 cyl, 3.0 L, Auto 7-spd, 6 cyl, 3.0 L, Auto 7-spd, 8 cyl, 5.5 L and Auto 9-spd, 8 cyl, 4.7 L. 2019 is the busiest model year in the record with 15 separate measured configurations, which is why a single quoted estimated annual fuel cost 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 S-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 S-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.

Frequently Asked Questions About S-Class Fuel Cost
