EV share in India's passenger vehicle market touched 5.1% in March 2026, its highest point in at least 12 months. CNG has quietly climbed from under 20% to nearly 24% of all sales. Here's the full fuel-type breakdown for Q1 2026 and the 12-month trend.
India's passenger vehicle market is undergoing a quiet but unmistakable fuel transition. The latest data from Vahan portal for March 2026 shows EV share reaching 5.1% — the highest level recorded in at least the past 12 months — while petrol's dominance continues to erode and CNG cements its position as the second-largest alternative fuel type in the country.
The total market in March 2026 stood at 4,36,081 units, up 9.5% month-on-month and a significant 22.9% year-on-year. Q1 2026 as a whole delivered 13,54,927 units across all fuel types.

EV Crosses 5% — A Psychological Milestone
The EV share number that will get the most attention is 5.1% in March 2026. In absolute terms that is 22,236 units — consistent with ElecTree's OEM-wise analysis published yesterday. But the share figure matters more than the absolute number in the long run, because it tells you how EVs are performing relative to the overall market, not just in isolation.
Tracking the trend makes the story clearer. EV share was 3.7% in April 2025. It climbed to 5.6% in both August and September 2025, then dipped sharply to 3.4% in October before recovering. March 2026's 5.1% suggests the market is finding a floor above 5% as newer models from Mahindra, Tata and Maruti build volume. The 66.7% year-on-year growth in EV registrations — from roughly 13,000 units in March 2025 to 22,236 in March 2026 — tells you the trajectory is firmly upward even if the monthly share fluctuates.
The Q1 2026 total for EVs stands at 56,289 units (ex-Telangana), with a healthy 10.8% quarter-on-quarter increase.
CNG: The Quiet Winner Nobody Is Talking About
If EVs get all the headlines, CNG is the story nobody is writing about. The fuel type that powers everything from auto-rickshaws to family sedans has grown its share from 19.7% in April 2025 to 23.9% in March 2026 — a gain of over 4 percentage points in 12 months. In absolute March 2026 terms, CNG registered 1,04,325 units, up 40.6% year-on-year — which is actually higher YoY growth than EVs.
CNG's rise is being driven by practical economics. Running costs are significantly lower than petrol, the infrastructure is better than most people acknowledge, and the Maruti Suzuki and Hyundai CNG lineups have expanded meaningfully. For buyers who do high daily mileage but can't yet justify an EV's upfront cost, CNG remains the most rational choice.
The 40.6% YoY growth rate for CNG versus 66.7% for EV does suggest EVs are growing faster from a lower base. But CNG's scale — over a lakh units per month — means it will remain a dominant force in the Indian market for years.
Petrol's Slow Retreat
Petrol started FY2025-26 at 48.9% share in April 2025 and ended Q1 FY2026-27 at 44.7% in March 2026. That is a 4.2 percentage point loss over 12 months — meaningful but not catastrophic. In absolute terms petrol still represents 1,94,840 units in March 2026, by far the largest single fuel type.
The decline is gradual and multi-directional — petrol is losing share to CNG, EVs and mild hybrids simultaneously. There is no single disruptor, just a broad-based shift toward more fuel-efficient options as buyers become more cost-conscious and the alternative vehicle ecosystem matures.
Diesel Holds Steady, Hybrids Disappoint
Diesel's share has been remarkably stable — ranging between 16.4% and 19.4% over the 12-month period, ending at 18.3% in March 2026. The 17.8% year-on-year growth in absolute diesel registrations is solid, suggesting the fuel isn't dying — it's just not growing its share. SUVs and long-distance users continue to sustain diesel demand.
Strong hybrids including PHEVs remain stuck at around 2% share — a number that has barely moved in 12 months despite aggressive marketing from Toyota and Maruti. The 1.1% year-on-year growth in March is almost negligible. Strong hybrids remain expensive relative to their CNG and EV alternatives, and the GST treatment continues to disadvantage them. Until that changes, 2% may be the ceiling.
Mild hybrids sit at 5.9% in March — relatively stable, mostly reflecting the prevalence of mild hybrid systems in Maruti and Hyundai petrol models as a standard fitment rather than a deliberate buyer choice.
LPG has effectively exited the market — 13 units registered in March 2026 versus 775 in January, a -98.6% year-on-year collapse. This fuel type can be considered extinct for practical purposes.
What This Means Going Forward
The fuel mix data for Q1 2026 tells a clear story: India's automotive market is in a multi-fuel transition, not a single-fuel revolution. EVs are growing fastest but from the smallest base. CNG is the volume alternative, growing steadily and sustainably. Petrol is declining but remains dominant. Diesel is holding its niche.
The most interesting number to watch in Q2 2026 will be whether EV share can break above 6% consistently. The Tata Sierra EV launch in May, combined with the Maruti eVitara ramping up and Mahindra's expanding lineup, gives the segment a strong shot at doing exactly that.
