Contribute to cardata.wiki

cardata.wiki gets better when people like you fix errors and fill in the gaps. Here's how to help.

1

Edit specs directly

The simplest way to contribute. Browse to any vehicle variant page, sign in, and you'll see edit pencil icons appear next to every spec field. Click a value, type the correct figure, and hit Save. Your change is logged in the revision history and immediately live on the page.

This is ideal for fixing a single wrong value — a misquoted power figure, an incorrect 0–100 time, a missing CO₂ rating. No spreadsheets, no forms, just click and fix.

Upload bulk CSV data

Have a spreadsheet of spec data for a make, model range, or production year? Upload it as a CSV from your dashboard. Our AI pipeline analyses the submission for consistency, flags potential issues, and sends it to our admin team for review. Once approved, the data is merged into the main database.

CSV format

Include a header row with any of the following columns (you don't need all of them):

Maximum file size: 10MB. Only .csv files accepted. By uploading, you confirm the data is yours to share and agree it will be published under CC BY 4.0.

Contribution guidelines

  • Use official sources where possible — Manufacturer press releases, owner's handbooks, and homologation documents are ideal. Avoid copying from sites that may themselves have errors.
  • Be precise with units — Power in bhp or kW, torque in Nm, economy in L/100km or mpg, dimensions in mm, weight in kg.
  • Don't invent data — Leave a field blank rather than guessing. A missing value is better than a wrong one.
  • No copyrighted data — Don't copy from proprietary databases, subscription services, or data that isn't yours to share.
  • All contributions are CC BY 4.0 — Anything you submit is published under a Creative Commons licence and will be freely reusable by anyone.
