Variants

Each variant is its own series with its own CSV. Not every variant is charted in the gallery — the CSV is the authoritative record either way.

History we hold

Every bar is the span actually present in our stored CSV — breaks in a bar are real gaps in the series, not rendering. Cadence is shown on the right.

Whole 2016-01–2026-06 (115 rows). Some rows additionally carry a time_interval of quarterly/yearly; the cadence shown is the spacing the periods actually have.

Which fuel columns this source fills

A blank column almost never means "no such cars" — it means this source does not split them out, and those vehicles are counted inside another column. Check the caveats for where they land.

reported column exists but is zero in every row not reported by this source. Hover a cell for the row count.

Caveats

Parsed positionally from a monthly PDF (Make × Importer × Fuel Type).
Each fetch reads a rolling ~6-month window; older months persist via upsert.
