Lexus RC data analysis
How Lexus RC estimated annual fuel cost varies
Across 41 configurations recorded for the 2015 through 2025 Lexus RC, estimated annual fuel cost runs from $2,900 to $4,000. The strongest figure belongs to the 2018 Lexus RC (Auto (S8), 4 cyl, 2.0 L) at $2,900, and the weakest to the 2018 car (Auto (S8), 8 cyl, 5.0 L) at $4,000 — a spread of 28%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Lexus RC would be misleading.
What changed for 2025
Average estimated annual fuel cost for the 2025 Lexus RC is $3,450, against $3,450 for the 2024 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.
How to read this Lexus RC data
This page lists every 2015 through 2025 Lexus RC record we hold for this measurement — 41 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 Lexus RC numbers
The 2015 through 2025 Lexus RC entries here cover the variants Auto (S6), 6 cyl, 3.5 L, Auto (S8), 4 cyl, 2.0 L, Auto (S8), 6 cyl, 3.5 L and Auto (S8), 8 cyl, 5.0 L. 2020 is the busiest model year in the record with 5 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 Lexus RC 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 Lexus RC 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.
