• Official figures from laboratory type-approval tests. VCA says they may not be achieved in real-world driving, and should not be used to rank cars with similar figures.
• NEDC figures (in VCA’s data until September 2018) and WLTP figures (from the 2019 guide) come from different tests, so they are shown separately and should not be compared.
• Plug-in hybrid figures are VCA’s weighted values, which count driving on battery power as well as on fuel.
• VCA’s data has no Mercedes-Benz versions for 2019, so the years listed may leave out years the Mercedes-Benz GLA-Class was on sale.
• Engine sizes are rounded to the nearest 0.1 litre. A version is one line in VCA’s data (description, gearbox, engine and fuel), counted once however many years it was listed. Matched from VCA’s model names “GLA Class, Model Year 2018”, “GLA Model Year 2023”, “GLA Model Year 2026”, “GLA Class, Model Year 2017”. How we use VCA’s figures.
