Alfa Romeo 4C data analysis
How Alfa Romeo 4C combined fuel economy varies
Across 6 configurations recorded for the 2015 through 2020 Alfa Romeo 4C, combined fuel economy runs from 28 MPG to 28 MPG. The strongest figure belongs to the 2015 Alfa Romeo 4C (Auto (AM6), 4 cyl, 1.8 L) at 28 MPG, and the weakest to the 2020 car (Auto (AM6), 4 cyl, 1.8 L) at 28 MPG — a spread of 0%. The narrow spread means any year of the Alfa Romeo 4C 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 2020
Average combined fuel economy for the 2020 Alfa Romeo 4C is 28 MPG, against 28 MPG for the 2019 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 Alfa Romeo 4C data
This page lists every 2015 through 2020 Alfa Romeo 4C 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 Alfa Romeo 4C 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 Alfa Romeo 4C 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.

The EPA highway loop never holds interstate speed. Here is what the same engine does when you sit on the cruise control.
| Cruise speed | EPA highway spec | AutoSpecData adjusted MPG | Fuel you lose |
|---|---|---|---|
| 60 mph | 34 MPG | 34 MPG | 0% |
| 65 mph | 34 MPG | 31.7 MPG | 7% |
| 70 mph | 34 MPG | 29.5 MPG | 13% |
| 75 mph | 34 MPG | 27.5 MPG | 19% |
| 80 mph | 34 MPG | 25.6 MPG | 25% |
Our Real-World Speed MPG Adjuster re-scales the Alfa Romeo 4C 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.
