Rolls-Royce Phantom data analysis

How Rolls-Royce Phantom combined fuel economy varies

Across 22 configurations recorded for the 2015 through 2027 Rolls-Royce Phantom, combined fuel economy runs from 13 MPG to 14 MPG. The strongest figure belongs to the 2015 Rolls-Royce Phantom (Auto (S8), 12 cyl, 6.7 L) at 14 MPG, and the weakest to the 2027 car (Auto (S8), 12 cyl, 6.7 L) at 13 MPG — a spread of 8%. The narrow spread means any year of the Rolls-Royce Phantom 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 Rolls-Royce Phantom is 13 MPG, against 14 MPG for the 2026 car — it fell by 1 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 Rolls-Royce Phantom data

This page lists every 2015 through 2027 Rolls-Royce Phantom record we hold for this measurement — 22 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 Rolls-Royce Phantom numbers

The 2015 through 2027 Rolls-Royce Phantom entries here span 13 model years of published measurements for this figure. 2017 is the busiest model year in the record with 4 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 Rolls-Royce Phantom 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 Rolls-Royce Phantom 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 Rolls-Royce Phantom 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.
