Battery electric vehicles in India recorded robust volume growth in 2025, yet their market share retreated late in the year after a government decision to reduce GST rates for petrol and diesel cars and two‑wheelers. Vahan registration data show that total battery-powered EV registrations across two‑wheelers, three‑wheelers and passenger vehicles rose 16% year on year to 22.7 lakh units, but narrowing price differentials helped internal combustion engine sales surge in the December quarter and dent penetration.
India EV penetration trends
Electric two‑wheelers, the largest volume segment, reported an 11% rise to 12.8 lakh units in 2025, up from 11.5 lakh in 2024. Penetration in the 2W segment climbed from 6% in 2024 to a high of 8.1% during January to September 2025, but a weaker share in the December quarter — the first after the GST reduction — pulled the full‑year penetration down to about 6.3%.
Passenger vehicle electrification made the most marked volume gain. Registrations of battery passenger vehicles (excluding hybrids) surged roughly 77% to 1.8 lakh units from about 99,500 units in 2024, helped by aggressive expansion from incumbent manufacturers and the entry of new producers. Even so, PV penetration for the year rose from 2.5% to nearly 4% as the lower relative price of petrol and diesel cars in the final quarter tempered EV market share gains.
The three‑wheeler segment bucked the year‑end trend. Electric three‑wheeler penetration, excluding e‑rickshaws, rose sharply to 18% in 2025 from 12% a year earlier. Volumes in the E3W category increased 15% to about 8 lakh units, and e‑rickshaws accounted for roughly 70% of total three‑wheeler EV sales during the year, underscoring strong demand in last‑mile and goods‑movement use cases.
Analysts attribute the slowdown in overall EV penetration in the closing quarter to the GST reduction, which narrowed the upfront cost gap between conventional and electric vehicles. That shift made a subset of buyers opt for petrol and diesel models when replacing or upgrading vehicles, producing a spike in ICE registrations that affected EV share despite healthy absolute EV volumes for the year.
Industry executives point to several longer‑term factors that still favour electrification. Falling battery costs, more competitive vehicle pricing, expanding model lineups and continued investment in public and private charging remain critical to sustaining conversion from ICE to EV. The strong 77% growth in passenger EV registrations shows demand responds when manufacturers broaden offerings and distribution networks.
Policy clarity will be important in determining how quickly India EV penetration recovers in 2026. Incentives, registration and tax treatments, and support for charging infrastructure all influence total cost of ownership calculations for buyers. The December GST move illustrated how fiscal changes can quickly alter purchasing behaviour.
Looking ahead, market observers expect EV volumes to keep growing but say momentum in market share will depend on a combination of competitive pricing, financing options and infrastructure rollout. If manufacturers and policymakers coordinate to reduce running costs and improve convenience, electrification in India could regain pace despite intermittent setbacks driven by tax changes.
Key Takeaways:
- India EV penetration eased in late 2025 after a GST cut for petrol and diesel narrowed the price gap, boosting ICE sales.
- Total battery EV registrations rose 16% to 22.7 lakh units in 2025, driven by strong growth in passenger EVs and stable gains in two- and three-wheelers.
- Electric three-wheelers showed the biggest penetration gain, rising to 18% as e-rickshaws accounted for about 70% of E3W sales.
- Policy certainty, incentives and charging infrastructure will determine whether India EV penetration rebounds in 2026.
