Mercedes-Benz GLC-Class data analysis
How Mercedes-Benz GLC-Class estimated annual fuel cost varies
Across 68 configurations recorded for the 2016 through 2027 Mercedes-Benz GLC-Class, estimated annual fuel cost runs from $2,600 to $4,450. The strongest figure belongs to the 2024 Mercedes-Benz GLC-Class (Auto 9-spd, 4 cyl, 2.0 L) at $2,600, and the weakest to the 2021 car (Auto 9-spd, 8 cyl, 4.0 L) at $4,450 — a spread of 42%. 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 GLC-Class would be misleading.
What changed for 2027
Average estimated annual fuel cost for the 2027 Mercedes-Benz GLC-Class is $2,850, against $3,100 for the 2026 car — it fell by $250. 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 GLC-Class data
This page lists every 2016 through 2027 Mercedes-Benz GLC-Class record we hold for this measurement — 68 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 GLC-Class numbers
The 2016 through 2027 Mercedes-Benz GLC-Class entries here cover the variants Auto 9-spd, 4 cyl, 2.0 L, Auto 9-spd, 6 cyl, 3.0 L, Auto 9-spd, 8 cyl, 4.0 L, Auto 7-spd, 4 cyl, 2.0 L and Auto (S9), 4 cyl, 2.0 L. 2019 is the busiest model year in the record with 9 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 GLC-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 GLC-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.
