Subaru Trailseeker data analysis

How Subaru Trailseeker combined fuel economy varies

Across 4 configurations recorded for the 2026 through 2027 Subaru Trailseeker, combined fuel economy runs from 114 MPG to 117 MPG. The strongest figure belongs to the 2026 Subaru Trailseeker (Auto (A1)) at 117 MPG, and the weakest to the 2027 car (Auto (A1)) at 114 MPG — a spread of 3%. The narrow spread means any year of the Subaru Trailseeker 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 2027

Average combined fuel economy for the 2027 Subaru Trailseeker is 116 MPG, against 116 MPG for the 2026 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 Subaru Trailseeker data

This page lists every 2026 through 2027 Subaru Trailseeker record we hold for this measurement — 4 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 Subaru Trailseeker 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 Subaru Trailseeker 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 Subaru Trailseeker 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.
