Jeep Grand Cherokee data analysis
How Jeep Grand Cherokee fuel tank capacity varies
Across 13 configurations recorded for the 2015 through 2027 Jeep Grand Cherokee, fuel tank capacity runs from 23 gallons to 24.6 gallons. The strongest figure belongs to the 2015 Jeep Grand Cherokee (Standard) at 24.6 gallons, and the weakest to the 2027 car (Standard) at 23 gallons — a spread of 7%. The narrow spread means any year of the Jeep Grand Cherokee 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 fuel tank capacity for the 2027 Jeep Grand Cherokee is 23 gallons, against 23 gallons 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 Jeep Grand Cherokee data
This page lists every 2015 through 2027 Jeep Grand Cherokee record we hold for this measurement — 13 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 Jeep Grand Cherokee numbers
The 2015 through 2027 Jeep Grand Cherokee entries here span 13 model years of published measurements for this figure. 2027 is the busiest model year in the record with 1 separate measured configuration, which is why a single quoted fuel tank capacity 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 Jeep Grand Cherokee 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 Jeep Grand Cherokee 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.
