Acura RLX data analysis

How Acura RLX estimated annual fuel cost varies

Across 11 configurations recorded for the 2015 through 2020 Acura RLX, estimated annual fuel cost runs from $2,550 to $3,300. The strongest figure belongs to the 2016 Acura RLX (Auto (AM7), 6 cyl, 3.5 L) at $2,550, and the weakest to the 2015 car (Auto (S6), 6 cyl, 3.5 L) at $3,300 — a spread of 23%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Acura RLX would be misleading.

What changed for 2020

Average estimated annual fuel cost for the 2020 Acura RLX is $3,000, against $3,000 for the 2019 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 Acura RLX data

This page lists every 2015 through 2020 Acura RLX record we hold for this measurement — 11 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 Acura RLX numbers

The 2015 through 2020 Acura RLX entries here cover the variants Auto (AM-S7), 6 cyl, 3.5 L, Auto (S10), 6 cyl, 3.5 L, Auto (S6), 6 cyl, 3.5 L and Auto (AM7), 6 cyl, 3.5 L. 2020 is the busiest model year in the record with 2 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 Acura RLX 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 Acura RLX 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.
