Aston Martin DBX V8 data analysis

Across 4 configurations recorded for the 2021 through 2024 Aston Martin DBX V8, engine displacement runs from 4 litres to 4 litres. The strongest figure belongs to the 2024 Aston Martin DBX V8 (SIDI) at 4 litres, and the weakest to the 2021 car (Auto 9-spd, 8 cyl, 4.0 L) at 4 litres — a spread of 0%.

What changed for 2024
Average engine displacement for the 2024 Aston Martin DBX V8 is 4 litres, against 4 litres for the 2023 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 DBX V8 data
This page lists every 2021 through 2024 Aston Martin DBX V8 record we hold for this measurement — 4 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 DBX V8 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 DBX V8 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.
