Render

Each new or changed month re-renders the country. Shares are read from the CSV as column ÷ TOTAL and grouped into three curves. A generalized Weibull S-curve is fitted to the BEV and the ICE share, and the charts, the fitted parameters, the twelve-month totals and the uncertainty bands are rewritten.

Which curve does a CSV column count towards?

BEVBEV
PHEV or EREV (plug-in hybrids, range extenders)
Does the source split plug-ins from other hybrids?
- yesPHEV
- no — one combined hybrid figure (parked in HEV)ICE
  the PHEV curve is left out, never drawn at zero
HEV or MHEV (full and mild hybrids — no plug)ICE
petrol, diesel, gas, flex-fuel, othersICE

Definitions & scope

Acquisition	File — downloaded as a data file (XLSX / Parquet / ODS / zip)
Vehicle scope	Whole = voitures particulières neuves (EU M1) — SUVs included; pickups, vans (N1), trucks (N2/N3) and buses (M2/M3) are separate categories (future variants).
HEV (full hybrids)	split into its own column
Backfill	Full énergie split monthly back to 2011-01 (the former ACEA series was BEV/PHEV-only and quarterly-interpolated before ~2025). Previous series parked as data/France_legacy.csv.
Auth	none

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.

Variant	What it counts	Held	Raw data
Whole	New passenger cars (voitures particulières, EU M1) with the full énergie split incl. a real HEV column, monthly from 2011-01.	2011-01 – 2026-10 190 rows	`data/France.csv`

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.

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.

Caveats

Raw (non-seasonally-adjusted) counts. The SDES/Insee CVS-CJO headline is seasonally & working-day adjusted and reads lower (e.g. June 2026 188 482 brut vs 142 100 CVS-CJO) — compare only against other raw figures.
vs the former ACEA rows there is a one-time per-fuel definitional step (HEV −3% / PETROL +3.5% / OTHERS +12%) — SDES counts 48V mild-hybrids as pure petrol (not HEV) and its "Gaz & ND" carries a not-yet-coded bucket. The headline BEV share is essentially unchanged vs ACEA — a few tenths of a pp with no consistent direction (see §3g).
The média download id rotates each publication; the fetcher download-and-verifies the current file from the monthly "Motorisations des véhicules légers neufs" publication (the parser is the arbiter, not the link label).
