Contribute data

The Index is built one sourced figure at a time. If you have a spec we’re missing — backed by a credible source — add it here. Every submission is verified by an editor before it appears, so the record stays trustworthy.

Find a car

Search or browse to any car, open it, and switch on contributor mode to see exactly which metrics are still missing.

Add a value with its source

Enter the figure and a link that backs it up. Every value must carry a source — no account needed.

We verify, then publish

An editor checks each submission against its source before it goes live, carrying an evidence mark and full provenance.
