Bihar Vehicle Registrations September 2025: 57,197 Units, −31.6% YoY
Full Vahan registration report for Bihar in September 2025 — total volume, year-on-year and month-on-month change, where the state ranks nationally, and the segment and fuel mix behind the number.
Bihar in September 2025
57,197 vehicles were registered in Bihar in September 2025. Volume fell steeply 31.6% against September 2024 and fell steeply 29.0% against August. Its best month on record remains October 2025 at 2,37,772.
That made Bihar the 14th largest vehicle market in India in September 2025, behind Delhi on 60,485 and ahead of Assam on 51,992.
That is 3.0% of every vehicle registered in the country that month, −1.64pp against September 2024.
Across 2025 to date — the 9 months of the year that have closed — Bihar has registered 9,48,539 vehicles, −3.3% on the same months of 2024.
Bihar monthly registrations
Every calendar year on record, month by month. The running month is left off the line until it closes.
What Bihar buys
80.8% of everything registered in Bihar in 2025 is two-wheelers, and the state accounts for 5.8% of that segment nationally. Against the national mix, Bihar skews towards two-wheelers — +9.05pp more of its book than India as a whole.
This split is the calendar year to date. Vahan publishes a state's registrations by month, and a state's registrations by vehicle class, but never the two together — so the volumes here cover 2025 rather than September 2025 alone. There is no manufacturer-by-state table anywhere in the source, which is why no page here claims to know which brand leads in Bihar.

"Share of segment" is this state against every other state in the same segment. "vs national mix" is how much more (or less) of this state's book the segment is than it is of India's.
What Bihar runs on
8.2% of Bihar's 2025 registrations are battery electric — 1,23,803 vehicles, against a national average of 8.0%. A year earlier the state was at 8.1%. CNG and LPG account for 3.3% here against 5.3% nationally.
Fuel, like segment, is published against the state for the whole calendar year rather than by month, so these shares are 2025 to date. Hybrids are counted separately from battery electrics.
| Fuel | 2025 units | Share in state | Share in India | vs 2024 |
|---|---|---|---|---|
| Petrol | 12,30,202 | 81.6% | 75.0% | −0.42pp |
| Diesel | 91,033 | 6.0% | 10.2% | +0.19pp |
| CNG / LPG | 50,356 | 3.3% | 5.3% | +0.16pp |
| Electric | 1,23,803 | 8.2% | 8.0% | +0.13pp |
| Hybrid | 6,505 | 0.4% | 1.3% | −0.04pp |
| Other | 5,278 | 0.4% | 0.3% | −0.02pp |
Every state, September 2025
Registrations by state for September 2025, exact and directly comparable — this is the one state table on the desk that has a real month axis behind it, so the year-on-year column compares the same month a year earlier rather than a part year against a whole one.

More from the reports desk
Source. Every figure is a vehicle registration, taken daily from the Ministry of Road Transport & Highways' Vahan 4 dashboard (vahan.parivahan.gov.in) — the same source FADA and the industry use for retail data. Registrations are not the wholesale dispatch numbers manufacturers announce each month. "EV" means battery electric (Vahan fuels PURE EV and ELECTRIC(BOV)); hybrids are counted separately. Information only, not investment advice.
