Acura NSX data analysis

How Acura NSX combined fuel economy varies

Across 6 configurations recorded for the 2017 through 2022 Acura NSX, combined fuel economy runs from 21 MPG to 21 MPG. The strongest figure belongs to the 2017 Acura NSX (Auto (AM-S9), 6 cyl, 3.5 L) at 21 MPG, and the weakest to the 2022 car (Auto (AM-S9), 6 cyl, 3.5 L) at 21 MPG — a spread of 0%. The narrow spread means any year of the Acura NSX in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

What changed for 2022

Average combined fuel economy for the 2022 Acura NSX is 21 MPG, against 21 MPG for the 2021 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 NSX data

This page lists every 2017 through 2022 Acura NSX record we hold for this measurement — 6 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 Acura NSX 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 NSX 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.

Our Real-World Speed MPG Adjuster re-scales the Acura NSX EPA highway result with a quadratic drag term (mpg = hwy ÷ (1 + k·(v² − 60²)/60²), k = 0.55 for trucks, SUVs and vans, 0.42 for cars). Wind, roof racks, and a heavy right foot make it worse, never better.
