Taiwan API

New-vehicle registration data for Taiwan from the Highway Bureau's national motor-vehicle register — monthly new registrations by vehicle kind and fuel, with battery-electric, plug-in, range-extender and hybrid each its own category — read from the Ministry of Transportation's statistics database.

Who sells the new cars

Whole · last 12 months (2025-10 → 2026-09) · 377,713 new registrations in total. Units are registrations; THB publishes brands only, no models. A brand is the registrant THB records; locally built cars appear under the local maker (國瑞 Kuozui for Toyota, 本田 Honda Taiwan, 三陽 San Yang for Hyundai, 福特六和 Ford Lio Ho, 日產 Yulon Nissan) and are merged with the marque's imports; China Motor (中華 — Mitsubishi and its own models) stays itself. THB's own "others" line (brands without a code of their own) counts towards the total but is not ranked; so do, since June 2026, about 600–850 cars a month that THB's total holds but no brand in the ministry's code list carries (a newly itemised brand the database does not list yet). Every powertrain together — THB publishes brands and fuels in two separate tables, so the brand ranking cannot be split into battery-electric, plug-in and combustion cars. Tesla, a battery-only brand, is the one maker whose units are all BEV.

Fetcher

Download

The fetcher reads the ministry's table page (which lists the newest month and the id of every vehicle kind and fuel), then one small JSON query per vehicle kind for the fuel table and one for the brand table — the same queries the database's own page sends. A normal run re-reads the newest 24 months, so a later correction by THB is picked up; nothing is written until every check below has passed.

Pick the vehicles

THB's vehicle kind (車種) decides the variant. Its definitions follow Taiwan's road-traffic rules (seats and gross weight), which line up with the EU classes.

THB vehicle kind?
  • 小客車 — passenger car, up to 9 seatsWhole
    private (自用) and commercial (營業 — taxis, rental cars) together
  • 小貨車 — goods vehicle up to 3.5 t (since 2020-09-04 also up to 5 t if at most 6 m long)Vans
  • 大貨車 — goods vehicle over 3.5 t, tractor units includedHDV
  • 大客車 — bus or coach, 10 seats or more, or over 3.5 tBuses
  • 特種車 (special vehicles), 機車 (motorcycles and mopeds)in no variant
Powertrain

THB records each vehicle's fuel (使用燃料) from its type approval in thirteen categories, each defined in the table's notes. They map one to one onto the gallery's columns; a category the fetcher does not know is counted as OTHERS and listed, and above 1% of a month's cars the run stops.

THB fuel category?
  • 電能 — electricity onlyBEV
  • 汽油/電能, 柴油/電能 (petrol or diesel plus electricity, mainly combustion) or 電能/汽油, 電能/柴油 (electricity plus petrol or diesel, mainly electric)PHEV
    from 2021-01 — before that, 汽油/電能 still held conventional hybrids
  • 電能(增程) — electric drive with a range-extender engineEREV
    folds into the PHEV curve in the charts
  • 汽油(油電), 柴油(油電) — fuel only, can drive on the electric motor (hybrid)HEV
  • 汽油(電能) — fuel only, driven only by the electric motor (Nissan e-POWER)HEV
    a series hybrid without a plug, not a BEV
  • 汽油 / 柴油PETROL/DIESEL
  • 液化石油氣, 汽油/液化石油氣 (LPG, petrol/LPG)LPG
Check against the brand table

The ministry publishes THB's new registrations a second time, by brand (table Seq 118), compiled separately. For every month and vehicle kind the fetcher writes, the brand table's total must equal the fuel table's — they have been identical for every month since 2012. A difference beyond 3 vehicles (0.1%) stops the run, as does a month whose fuels do not add up to the table's own total.

data/Taiwan.csv
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

AcquisitionAPI — pulled from a structured API / query endpoint
Vehicle scopeNew registrations (新領牌照) of vehicles with a regular Taiwanese plate — military vehicles, unregistered vehicles and temporary plates excluded — counted in the month the plate was issued. Motorcycles and special vehicles are in no variant.
HEV (full hybrids)THB's own fuel categories separate battery-electric, plug-in hybrid (four combined-fuel codes — petrol or diesel plus electricity, combustion- or electric-led), range extender (EREV) and hybrid. HEV is the register's hybrid codes 汽油(油電) / 柴油(油電) plus 汽油(電能) (driven only by the motor, fuelled only by petrol — Nissan e-POWER). The register has no mild-hybrid code; a 48 V mild hybrid sits in whichever of petrol or hybrid its type approval names.
Backfillfrom 2021-01, the first month in which the plug-in codes hold plug-ins only — before that the code 汽油/電能 still carried conventional full hybrids (§4)

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.

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

Freshness. Latest period in our store: 2026-09. Update cadence: twice daily on the 12th–28th, 01:45 and 09:45 UTC — MOTC publishes month M around the 15th of M+1 (August 2026 on September 15).
