GMC Sierra data analysis
How GMC Sierra EPA electric range varies
Across 4 configurations recorded for the 2025 through 2026 GMC Sierra, EPA electric range runs from 283 miles to 410 miles. The strongest figure belongs to the 2026 GMC Sierra (Auto (A1)) at 410 miles, and the weakest to the 2026 car (Auto (A1)) at 283 miles — a spread of 45%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the GMC Sierra would be misleading.
What changed for 2026
Average EPA electric range for the 2026 GMC Sierra is 359 miles, against 390 miles for the 2025 car — it fell by 30.7 miles. 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 GMC Sierra data
This page lists every 2025 through 2026 GMC Sierra 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 GMC Sierra 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 GMC Sierra 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.
