Maserati Grancabrio data analysis
How Maserati Grancabrio combined fuel economy varies
Across 6 configurations recorded for the 2024 through 2026 Maserati Grancabrio, combined fuel economy runs from 20 MPG to 83 MPG. The strongest figure belongs to the 2026 Maserati Grancabrio (Auto (A1)) at 83 MPG, and the weakest to the 2026 car (Auto 8-spd, 6 cyl, 3.0 L) at 20 MPG — a spread of 315%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Maserati Grancabrio would be misleading.
What changed for 2026
Average combined fuel economy for the 2026 Maserati Grancabrio is 51.5 MPG, against 51 MPG for the 2025 car — it rose by 0.5 MPG. That is a real improvement, and it is the kind of change worth paying the newer-year premium for if this figure drives your decision.
How to read this Maserati Grancabrio data
This page lists every 2024 through 2026 Maserati Grancabrio 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 Maserati Grancabrio 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 Maserati Grancabrio 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 Maserati Grancabrio 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.
