  • 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 Smart versions for 2019, so the years listed may leave out years the Smart Forfour was on sale.
  • VCA’s data has no Smart versions for 2022, so the years listed may leave out years the Smart Forfour 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 “forfour”, “forfour, Model Year 2017”, “Forfour”, “forfour, Model Year 2016”. How we use VCA’s figures.

  • Figures cover Great Britain (England, Scotland and Wales). Northern Ireland is not included.
  • Licensed counts are vehicles with a current tax or exemption at the end of each year (or the latest quarter). SORN counts are shown separately.
  • First registrations count vehicles registered in Great Britain for the first time, including used imports.
  • Models are grouped by DVLA’s generic model name, so every generation and trim counts together.
  • MOT figures cover normal tests of cars aged three and over in 2025; retests are excluded. Age is rounded to the nearest year.
  • DVSA records the model name typed in at the test. We match those names to DVLA’s generic models, so a handful of tests may be counted under a close relative.
