Aston Martin DBS data analysis

How Aston Martin DBS combined fuel economy varies

Across 5 configurations recorded for the 2019 through 2023 Aston Martin DBS, combined fuel economy runs from 17 MPG to 17 MPG. The strongest figure belongs to the 2019 Aston Martin DBS (Auto (S8), 12 cyl, 5.2 L) at 17 MPG, and the weakest to the 2023 car (Auto 8-spd, 12 cyl, 5.2 L) at 17 MPG — a spread of 0%. The narrow spread means any year of the Aston Martin DBS 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 2023

Average combined fuel economy for the 2023 Aston Martin DBS is 17 MPG, against 17 MPG for the 2022 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 Aston Martin DBS data

This page lists every 2019 through 2023 Aston Martin DBS record we hold for this measurement — 5 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 Aston Martin DBS 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 Aston Martin DBS 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	22 MPG	22 MPG	0%
65 mph	22 MPG	20.5 MPG	7%

Our Real-World Speed MPG Adjuster re-scales the Aston Martin DBS 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.
