Mercedes-Benz GL-Class data analysis
How Mercedes-Benz GL-Class engine displacement varies
Across 6 configurations recorded for the 2015 through 2016 Mercedes-Benz GL-Class, engine displacement runs from 3 litres to 5.5 litres. The strongest figure belongs to the 2016 Mercedes-Benz GL-Class (SIDI) at 3 litres, and the weakest to the 2015 car (SIDI) at 5.5 litres — a spread of 45%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the Mercedes-Benz GL-Class would be misleading.
What changed for 2016
Average engine displacement for the 2016 Mercedes-Benz GL-Class is 4.4 litres, against 4.4 litres for the 2015 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 GL-Class data
This page lists every 2015 through 2016 Mercedes-Benz GL-Class 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 Mercedes-Benz GL-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 GL-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.
