Bihar Vehicle Registrations August 2026: 1,04,746 Units, +29.9% YoY

1,04,746 vehicles were registered in Bihar in August 2026. Volume climbed sharply 29.9% against August 2025 and declined 9.3% against July. Its best month on record remains October 2025 at 2,37,766.

That made Bihar the 9th largest vehicle market in India in August 2026, behind Kerala on 1,08,192 and ahead of Andhra Pradesh on 94,731.

That is 4.2% of every vehicle registered in the country that month, +0.35pp against August 2025.

Across 2026 to date — the 8 months of the year that have closed — Bihar has registered 10,52,483 vehicles, +18.1% on the same months of 2025.

78.0% of everything registered in Bihar in 2026 is two-wheelers, and the state accounts for 5.3% of that segment nationally. Against the national mix, Bihar skews towards two-wheelers — +6.93pp more of its book than India as a whole.

This split is the calendar year to date. Our Vahan data holds a state's registrations by month, and a state's registrations by vehicle class, but not the two together — so the volumes here cover 2026 rather than August 2026 alone. It holds no manufacturer-by-state table either, which is why no page here says which brand leads in Bihar.

10.7% of Bihar's 2026 registrations are battery electric — 1,45,537 vehicles, against a national average of 10.7%. A year earlier the state was at 8.2%. CNG and LPG account for 3.7% here against 5.6% nationally.

Fuel, like segment, is published against the state for the whole calendar year rather than by month, so these shares are 2026 to date. Hybrids are counted separately from battery electrics.

Registrations by state for August 2026, 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.

The last 15 months on record for Bihar. The running month is left without a year-on-year figure.
