CNG Conversion in India: 50 Key Statistics 2026
Data Report · Updated May 2026 CNG Conversion in India: 50 Key Statistics 2026 A comprehensive data reference on India’s CNG vehicle market — growth, infrastructure, savings, and adoption trends — for researchers, journalists, and automotive buyers. India is among the top 3 CNG vehicle markets in the world. With a rapidly expanding city gas distribution network, rising petrol prices, and government push for cleaner fuels, CNG adoption has accelerated significantly between 2020 and 2026. This report consolidates 50 key statistics across market size, infrastructure, cost savings, environmental impact, and vehicle data. Data sourced from MoPNG (Ministry of Petroleum & Natural Gas), PNGRB (Petroleum and Natural Gas Regulatory Board), IGL, MGL, SIAM, and publicly available government reports. Where exact 2026 figures are unavailable, 2024–25 data with growth trend projections is used. 1. Market Size & Growth 7M+CNG vehicles on Indian roads (2025–26)MoPNG estimate #3India’s rank globally in CNG vehicle populationAfter China & Iran 22%CAGR of India’s CNG vehicle market (2020–2025)Industry estimate 10M+Target CNG vehicles by 2028 (government projection)MoPNG India’s CNG vehicle fleet grew from ~3.4 million in 2020 to over 7 million by 2025 — doubling in five years driven by rising petrol prices and CGD expansion. The passenger vehicle segment accounts for ~65% of all CNG vehicles in India; the rest are 3-wheelers, buses, and commercial vehicles. CNG penetration in the new car market crossed 12% in FY2025 — one in eight new cars sold now has CNG capability (factory-fitted or aftermarket). The aftermarket CNG kit industry is estimated at ₹2,500–3,500 crore annually, with over 4,000 authorised installation centres across the country. India’s natural gas consumption target is 15% of the energy mix by 2030 — currently at ~6%. CGD and CNG vehicles are a key lever to achieve this goal. Gujarat and Delhi NCR collectively account for ~45% of all CNG vehicle registrations in India. The Indian government has allocated CGD licences to 400+ geographical areas covering 28 states and 8 union territories as of 2025. 2. CNG Infrastructure — Stations & Network 6,500+CNG stations across India (2025–26)MoPNG / PNGRB 600+IGL CNG stations in Delhi NCRIndraprastha Gas Ltd 320+MGL stations in Mumbai regionMahanagar Gas Ltd 10,000Target CNG stations by 2030MoPNG Vision 2030 Delhi NCR has the densest CNG station network in India with IGL operating 600+ stations — one station roughly every 3–4 km in central Delhi. Gujarat’s network (IGL, Gujarat Gas, GSPC Gas) operates 1,200+ CNG stations making it the state with the highest CNG station count. Mumbai’s MGL network covers Mumbai, Thane, Raigad, and Navi Mumbai with 320+ stations and plans to expand to 400+ by 2027. India added approximately 800–1,000 new CNG stations per year between 2022 and 2025 — among the fastest infrastructure build-outs globally. CGD networks now cover over 300 districts across India, with tier-2 and tier-3 city expansion accelerating post-2023. Average CNG station fuelling time is 5–8 minutes — comparable to petrol; long queues common in Delhi NCR during peak hours (7–10 AM, 5–8 PM). PNGRB’s 10th round of CGD bidding (2023–24) allocated licences for 50+ new geographical areas, adding ~8 crore potential households to the gas grid. 3. Cost & Fuel Savings Statistics Metric Delhi NCR Mumbai Ahmedabad CNG Price (per kg) ₹75–78 ₹80–84 ₹80–86 Petrol Price (per litre) ₹95–97 ₹103–106 ₹95–98 CNG Cost per km (avg) ₹2.8–3.5 ₹3.0–3.8 ₹3.0–4.0 Petrol Cost per km (avg) ₹6.5–8.0 ₹7.0–8.5 ₹6.5–8.0 Savings per km ₹3.5–4.5 ₹3.5–5.0 ₹3.0–4.5 On average, CNG costs 55–65% less per kilometre than petrol for Indian passenger cars — the single biggest financial argument for conversion. A driver doing 1,500 km/month saves ₹5,000–₹7,500 every month after switching to CNG (basis Delhi NCR fuel prices, May 2026). At this savings rate, a ₹40,000 CNG kit pays for itself in 6–8 months — one of the fastest ROI modifications available for a passenger vehicle. Over 5 years of ownership, a CNG car user saves ₹3–4.5 lakh in fuel costs compared to a petrol-only driver (1,500 km/month basis). CNG kit prices range from ₹35,000 for basic sequential kits to ₹78,000 for Direct Injection (TGDI engine) kits — depending on car model and cylinder size. The 90-litre CNG cylinder (18 kg capacity) provides approximately 450–500 km range on a full tank — comparable to a petrol car’s full tank range. CNG mileage on Indian cars averages 20–36 km/kg — when converted to petrol-equivalent, this is approximately 28–50 km/litre. Monthly maintenance cost of a CNG kit is near-zero — standard service every 10,000 km alongside normal car servicing; kit components typically last 5–8 years. 📊 Key insight: The break-even point for CNG conversion in India has shortened from ~14 months in 2019 to ~7 months in 2026 — primarily due to rising petrol prices and improved kit technology. 4.

Maruti Suzuki sold over 5.5 lakh CNG cars in FY2025 — accounting for roughly 1 in 4 Maruti cars sold being CNG-powered. Hyundai’s CNG lineup (Grand i10 Nios, Aura, i20, Verna) grew 38% year-on-year in FY2025 — the company’s fastest-growing powertrain segment. Tata Motors entered the factory-fitted CNG space aggressively — Tiago CNG and Tigor CNG collectively sold 80,000+ units in FY2025. The aftermarket CNG kit segment is dominated by Italian brands — Lovato, Mijo, Gastech, and Motozen — which collectively hold ~70% market share in the organised installation segment. Direct Injection CNG kits (for turbocharged engines) emerged as a significant
