Editorial policy

The rules we work to

Stated here so a reader can hold us to them.

1. Every figure is sourced or marked as ours

Every technical value either rests on a source or is marked as our own. The source is, for vehicle data, the vehicle or component maker’s own documents; for a rule, limit or charge, the legal text or the official body that applies it; for a statistic, the body that issues it. Where a page relies instead on a report of a figure, such as a trade-press article, it lists that report. Where a sentence adds our own arithmetic to sourced figures, or works an example on an input of our own, it says so. Every article and model page lists its sources in full, and this is enforced by the publishing system itself: such a page with no sources will not build. Pages are checked against the sources they cite by a separate pass from the one that wrote them; for pages with a publication date before 9 September 2026, a source-by-source check of every citation has now been completed for all of them.

2. Unconfirmed is left blank

A specification that cannot be confirmed in the maker’s own documents is omitted, not estimated. Gaps in the tables on this site are deliberate. Where a manufacturer’s own documents conflict, we say so on the page instead of quietly picking one: the value is left out, both are given, or the page names the document it follows and why.

3. Data is not translated

Specifications are held once per model and rendered into every language from that one record; their numbers are not re-entered, so they cannot drift between language versions. Labels and article text are translated from the English, and figures quoted in article text are translated with it; each translation is checked against the English, and for pages with a publication date before 9 September 2026 that sentence-by-sentence check has now been completed for all of them. Before every upload the five core versions of each topic are compared figure by figure, and a figure that one language has and another lacks stops the upload. A Polish, Italian or French version goes live only once it carries the same figures, and one left behind by a later correction is listed and corrected without holding the others. The free-text entries in a specification record — its source notes and descriptive values such as the transmission, variant, door and seating descriptions — are translated on each language’s page, and every figure in them is checked against the record.

4. Photographs are verified by eye

Cover images are freely licensed and credited with photographer and licence. Each is checked against the subject before publication, because a filename is not evidence of what a photograph shows.

5. Commercial interests are disclosed

This site shares an owner with a spare parts manufacturer. That is stated on the about page. We do not link to that company’s products or catalogue, and the owner has decided that we will not; a manufacturer’s own technical document is linked only where it is the source of something the page states, and any commercial link added later would be marked as sponsored and disclosed. None of this affects where technical data comes from.

6. Corrections are made and shown

When we get something wrong we change it and record that we did. Send a correction with the source that contradicts us.

7. AI use is stated

Pages are researched, drafted and translated with AI language models under these rules; how, and what is checked, is set out on the About page.
