Technical reference
About
What this site is
An independent technical reference for trucks, buses and trailers, published in eight languages: English, German, Turkish, Russian, Spanish, Polish, Italian and French. Every article and model page lists the sources its figures come from.
What we publish
Model specifications you can check against the manufacturer, explanations of the vehicle segments these machines work in, the operating knowledge it takes to run them legally and profitably, and coverage of the industry that builds them.
The site is written for people who work with these vehicles: operators, fleet engineers, workshop staff and parts buyers. It is not written for enthusiasts, and it is not a dealer.
How the technical data is produced
Every specification is taken from the vehicle or component maker’s own documents, such as a technical data sheet, brochure, product page, press release, or owner’s or body-builder manual, and every rule, limit or charge from the legal text or the official body that applies it. Where a page relies instead on a report of a figure, such as a trade-press article or an industry body’s summary, its Sources list names that report. We do not test vehicles, so a specification here is the maker’s published figure, not an independently confirmed one. Where a sentence adds our own arithmetic to sourced figures, or works an example on an input of our own, it says so.
Article and model pages are checked against the sources they cite by a separate pass from the one that wrote them; the rule is that a figure not found in its source is left out. The English page is checked against its sources, and each translation is then checked against the English. Pages with a publication date before 9 September 2026 were written before this pass existed; a source-by-source check of every citation and a sentence-by-sentence check of each translation against the English has now been completed for all of them.
A blank or missing value on this site means it could not be confirmed in a primary document in the form the table needs — it was not found, it is published only in a unit we do not convert, or the maker publishes it inconsistently — not that it does not exist. A field that does not apply to a vehicle, such as displacement for an electric motor, is simply not shown. Where a manufacturer’s own documents contradict one another, the page says so rather than quietly choosing the more convenient number: the value is left out, both figures are given, or the page names the document it follows and why. Most model pages here carry a section naming what could not be confirmed.
Specifications live in one language-neutral record per model and are rendered into each language’s model page from it (model pages exist in all eight languages). A torque figure in a specification table is therefore identical in every language by construction. Labels and article text are translated from the English, and figures quoted in article text are translated with it. 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.
How the pages are written
The pages on this site are researched, drafted and translated with AI language models (Anthropic’s Claude), working to the rules on this page and in the editorial policy, which the site’s owner sets and maintains. A model finds and reads the sources and writes the English page; a separate pass checks the page against the sources it cites, and a figure that is not found in its source is taken out. Each translation is then made from the English and read against it. Before every upload, scripts compare the language versions of each page figure by figure; a version that differs is not uploaded. Cover photographs are checked by eye.
The owner decides which subjects are covered and approves these rules; pages are not reviewed sentence by sentence by a human specialist before they are published.
Photographs
Cover images are freely licensed works from Wikimedia Commons, credited to the photographer with their licence on every page. Each one is checked by eye against the subject before publication — a filename is not evidence that a photograph shows the vehicle it claims to.
Our commercial interest
TruckBusWorld is operated by the same company as Vaden, a manufacturer of heavy
commercial vehicle spare parts. This site does not link to Vaden’s products or
catalogue, and the owner has decided that it will not. A manufacturer’s own
technical document, Vaden’s included, is linked only where it is the source of a
figure or statement on the page. If a commercial link is ever added, it will be
marked rel="sponsored" and disclosed.
We publish this because a reader weighing our technical judgement is entitled to know it. It does not change how the data is sourced: the specifications here are the manufacturers’ published figures, not ours — where a page adds its own arithmetic, it says so — and each can be checked against the sources listed on the page.
Corrections
If a figure on this site is wrong, we want to fix it and say that we did. Write to us with the page and the source that contradicts it.
