Kia Niro data analysis
How Kia Niro combined fuel economy varies
Across 43 configurations recorded for the 2017 through 2027 Kia Niro, combined fuel economy runs from 43 MPG to 113 MPG. The strongest figure belongs to the 2023 Kia Niro (Auto (A1)) at 113 MPG, and the weakest to the 2022 car (Auto (AM-S6), 4 cyl, 1.6 L) at 43 MPG — a spread of 163%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Kia Niro would be misleading.
What changed for 2027
Average combined fuel economy for the 2027 Kia Niro is 50 MPG, against 65.8 MPG for the 2026 car — it fell by 15.8 MPG. 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 Kia Niro data
This page lists every 2017 through 2027 Kia Niro record we hold for this measurement — 43 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 Kia Niro numbers
The 2017 through 2027 Kia Niro entries here cover the variants Auto (AM-S6), 4 cyl, 1.6 L, Auto (A1) and Auto (AM6), 4 cyl, 1.6 L. 2022 is the busiest model year in the record with 5 separate measured configurations, which is why a single quoted combined fuel economy 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 Kia Niro 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 Kia Niro 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 Kia Niro 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.
