Where our data comes from

12,686 source pages · 1,743 siteslatest read

91,752 figures on our model pages rest on 12,686 source pages from 1,743 sites. Below: what kind of source each is, and which sources we never use.

Which kinds of source do we use?

55 % of the shown figures come from a primary source: the maker, a regulator or an independent test. Every figure links its own source and the date we read it.

How do I check a figure?

  1. 1. Open the model page of the car.
  2. 2. Next to each figure, its mark opens the source and the date we read it.
  3. 3. Open the source and compare. Found a mismatch? Report it on the corrections page.
