Brazil Vehicle Fleet by Municipality and Fuel Type (monthly)

The registered vehicle fleet of Brazil, by municipality, fuel type and month, 2014-01 to 2026-09 (September 2026), from the national vehicle register (RENAVAM) as published by SENATRAN. Cleaned, typed, joined to the official IBGE municipality codes and given a powertrain class (ICE, FLEX, BEV, PHEV, HEV, FCEV and two honest "unspecified" classes), in English column names. Updated monthly; the latest month in this build is 2026-09, with 136,424,856 registered vehicles.

Per-station fuel prices and ethanol/gasoline parity: on the Apify Store. The companion dataset pracadata/brazil-fuel-prices has weekly fuel prices by municipality (free).

Read this first: what this data is not

• Registered fleet is not the fleet on the road. SENATRAN counts vehicles in the register. Scrapped, exported or abandoned vehicles that were never de-registered are still counted, so every total is an upper bound of vehicles in circulation, and old-vehicle counts are the most inflated.
• Most of the electrified stock is not classified as BEV, PHEV or HEV. The register used combined fuel labels ("Gasolina/Elétrico" and similar) that do not say whether a car is a plain hybrid or a plug-in. They are kept as HYBRID_UNSPECIFIED. Likewise "Elétrico/Fonte Externa" and "Elétrico/Fonte Interna" are ELECTRIC_UNSPECIFIED: they include trolleybuses, electric motorcycles and electric bicycles, and they are not battery cars. In September 2026 HYBRID_UNSPECIFIED and ELECTRIC_UNSPECIFIED together outnumber BEV, PHEV and HEV several times over.
• BEV, PHEV and HEV only exist from April–October 2022. The register added the codes "Híbrido Plug-in" (April 2022), "Híbrido" (August 2022) and "Elétrico" (October 2022) then. Before that, every such vehicle sits in the unspecified classes. Do not compare BEV, PHEV or HEV counts across those dates. electrified_share is comparable over the whole period (it excludes ELECTRIC_UNSPECIFIED and includes HYBRID_UNSPECIFIED); electrified_share_incl_unspecified_electric also counts the electric-unspecified class.
• 3.6% of the fleet has no fuel information ("Sem Informação" and similar; 4,963,295 vehicles in September 2026). They are kept as UNKNOWN. Rows whose state itself is "Sem Informação" have state = 'UNKNOWN'; they appear in fleet_state_monthly so that national totals match the source, and not in the municipality tables.
• Period starts in January 2014. SENATRAN's fuel spreadsheets for May–December 2013 are Microsoft Access databases and are not included.
• Municipality names changed over time in the source; the ones that do not match IBGE's official name were mapped by hand to the IBGE code (about 40 spellings, such as Paraty, Embu das Artes, Tacima). One district of São Paulo state, Ibitiúva, appears for seven months as if it were a municipality and has no code.
• One source file (August 2026) has a grand-total row; it is removed (otherwise national totals double).

Powertrain classes: ICE (gasoline, diesel, ethanol, with or without a CNG kit), FLEX (ethanol/gasoline), BEV, PHEV, HEV, FCEV (fuel cell), HYBRID_UNSPECIFIED, ELECTRIC_UNSPECIFIED, UNKNOWN. cng_kit is true when natural gas appears together with another fuel. Full mapping in the data dictionary.

Examples

Top municipalities by electrified share (at least 10,000 vehicles), latest month, in DuckDB:

select municipality_name, state, round(100 * electrified_share, 2) as electrified_pct, total_vehicles
from 'hf://datasets/pracadata/brazil-vehicle-fleet/data/fleet_electrification_monthly.parquet'
where year_month = '2026-09' and total_vehicles >= 10000
order by electrified_share desc limit 10;

The same in pandas (needs pyarrow and huggingface_hub installed):

import pandas as pd
df = pd.read_parquet("hf://datasets/pracadata/brazil-vehicle-fleet/data/fleet_electrification_monthly.parquet")
top = df[(df.year_month == "2026-09") & (df.total_vehicles >= 10_000)].nlargest(10, "electrified_share")
print(top[["municipality_name", "state", "electrified_share", "total_vehicles"]])
