Mercedes-Benz A-Class data analysis

How Mercedes-Benz A-Class engine displacement varies

Across 11 configurations recorded for the 2019 through 2022 Mercedes-Benz A-Class, engine displacement runs from 2 litres to 2 litres. The strongest figure belongs to the 2022 Mercedes-Benz A-Class (SIDI) at 2 litres, and the weakest to the 2019 car (SIDI) at 2 litres — a spread of 0%. The narrow spread means any year of the Mercedes-Benz A-Class 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 2022

Average engine displacement for the 2022 Mercedes-Benz A-Class is 2 litres, against 2 litres for the 2021 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 Mercedes-Benz A-Class data

This page lists every 2019 through 2022 Mercedes-Benz A-Class record we hold for this measurement — 11 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 Mercedes-Benz A-Class numbers

The 2019 through 2022 Mercedes-Benz A-Class entries here span 4 model years of published measurements for this figure. 2022 is the busiest model year in the record with 3 separate measured configurations, which is why a single quoted engine displacement 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 Mercedes-Benz A-Class 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 Mercedes-Benz A-Class 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.
