• 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.
• Electric cars produce no exhaust CO2; range and miles per kWh are VCA’s official figures.
• VCA’s data has no Mercedes-Benz versions for 2019, so the years listed may leave out years the Mercedes-Benz G-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 “G-Class Model Year 2026”, “G-Class Model Year 2023”, “G-Class Model Year 2025”, “G-Class Model Year 2027”. How we use VCA’s figures.
