Tamil Nadu Vehicle Registrations December 2025: 1,75,676 Units, +56.6% YoY

1,75,676 vehicles were registered in Tamil Nadu in December 2025. Volume rocketed 56.6% against December 2024 and fell back 11.2% against November. Its best month on record remains January 2026 at 2,59,452.

That made Tamil Nadu the 3rd largest vehicle market in India in December 2025, behind Uttar Pradesh on 2,32,364 and ahead of Gujarat on 1,69,526.

That is 8.2% of every vehicle registered in the country that month, +2.12pp against December 2024.

Across 2025 to date — the 12 months of the year that have closed — Tamil Nadu has registered 21,18,505 vehicles, +8.4% on the same months of 2024.

76.7% of everything registered in Tamil Nadu in 2025 is two-wheelers, and the state accounts for 7.7% of that segment nationally. Against the national mix, Tamil Nadu skews towards two-wheelers — +4.94pp 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 2025 rather than December 2025 alone. It holds no manufacturer-by-state table either, which is why no page here says which brand leads in Tamil Nadu.

7.8% of Tamil Nadu's 2025 registrations are battery electric — 1,66,234 vehicles, against a national average of 8.0%. A year earlier the state was at 6.7%. CNG and LPG account for 3.1% 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.

Registrations by state for December 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.

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