With petrol prices refusing to cool down, more and more Indian car buyers are turning to CNG vehicles — and honestly, it makes a lot of sense. Running a CNG car can cost up to 50% less than petrol, the mileage numbers are impressive, and the emissions are cleaner. As of 2026, there are 41 CNG models available in India, with prices starting from just ₹3.50 lakh. Factory-fitted S-CNG kits have also made these cars safer and more reliable than ever before.
Here’s a detailed look at the top 10 best CNG cars in India right now.
Why CNG Cars Are Gaining Popularity in India
The simple and short answer is that they save you real money every single month.
CNG is 50 to 60% cheaper than petrol, and modern CNG cars deliver between 20 and 34 km per kg. They emit less CO₂ than petrol or diesel vehicles, and with factory-fitted kits now standard across most models, you don’t have to worry about dodgy aftermarket conversions or voided warranties. Some states also offer lower road tax and registration fees for CNG vehicles.
If you’re a daily commuter, a cab operator, or a family clocking high monthly kilometres, a CNG car is one of the smartest financial decisions you can make in 2026.
Top 10 Best CNG Cars in India – Complete List
1. Maruti Suzuki Wagon R S-CNG — Best Entry-Level Hatchback
Price: ₹5.00 lakh (ex-showroom) | Mileage: 34.05 km/kg
The Wagon R has been a household name in India for decades, and the S-CNG version continues to earn its reputation. With the highest mileage of any CNG car in this segment, a spacious tallboy cabin that feels bigger than it looks from outside, and dual airbags plus ABS as standard, this is the go-to choice for budget city commuters who want maximum efficiency without spending a lot.
2. Maruti Suzuki Celerio S-CNG — Best CNG Mileage Hatchback
Price: ₹5.50 lakh (ex-showroom) | Mileage: 34.4 km/kg
If squeezing every last kilometre out of a tank matters to you, the Celerio S-CNG is technically the highest-mileage CNG car in India right now. The AMT automatic option makes it especially convenient in stop-and-go city traffic, where manual gear changes become tiring quickly. Spacious interior, dual airbags, ABS — it covers the basics well and then goes further with that extraordinary mileage figure.
3. Maruti Suzuki Swift S-CNG — Best Sporty Hatchback
Price: ₹5.79 to ₹8.8 lakh | Mileage: 26.73 km/kg
The Swift has always had a certain energy to it — it looks sharper than most cars in its price range and drives with more confidence too. The S-CNG version keeps that sporty character alive while adding real-world fuel savings. With i-Automation features, rear AC vents, and dual airbags, this is the CNG car for someone who doesn’t want to feel like they compromised on style just to save on fuel.
4. Maruti Suzuki Baleno S-CNG — Best Value Hatchback
Price: ₹5.99 to ₹9.1 lakh | Mileage: 23.94 to 30.6 km/kg
The Baleno punches above its weight in terms of features. A 360-degree camera, Apple CarPlay and Android Auto, LED headlights, and a premium interior — these are things you’d expect from a car costing more. The CNG version brings all of that while keeping running costs low. For families who want a feature-rich hatchback without paying premium prices, the Baleno S-CNG is hard to beat.
5. Toyota Glanza CNG — Best Premium Hatchback
Price: ₹6.45 to ₹9.20 lakh | Mileage: 24.0 km/kg
Technically a cousin of the Baleno, the Glanza brings Toyota’s brand reliability and after-sales network into the picture. The features are very similar — 360-degree camera, touchscreen, Apple CarPlay — but Toyota’s reputation for long-term dependability gives some buyers extra peace of mind. If the brand name and service experience matter to you, the Glanza CNG is worth the slightly higher price.
6. Tata Tiago CNG — Best Safe Hatchback
Price: ₹5.80 to ₹7.95 lakh | Mileage: 26.49 km/kg | Safety: 4-star Global NCAP
Safety is where the Tiago stands apart. A 4-star Global NCAP rating is genuinely impressive for a car at this price point, and Tata’s build quality has a reputation for being solid and durable. It’s not the flashiest car on this list, but if protecting your family is the top priority and you want CNG efficiency alongside it, the Tiago makes a very strong case.
7. Tata Punch i-CNG — Best Micro SUV
Price: ₹6.75 lakh (ex-showroom) | Mileage: 23.0 km/kg | Safety: 5-star Bharat NCAP
This is arguably the most impressive CNG car on this entire list. Five-star Bharat NCAP safety rating, 6 airbags, ESP, 187mm ground clearance, and a twin-cylinder CNG system that actually leaves you usable boot space — the Punch i-CNG has thought about the things that matter. If you want a micro-SUV that looks good, sits high, keeps your family safe, and saves you money on fuel, this is it.
8. Maruti Suzuki Dzire S-CNG — Best CNG Sedan
Price: ₹6.26 to ₹9.32 lakh | Mileage: 24.12 km/kg | Boot Space: 378L
Sedans have fallen out of fashion a bit in India’s SUV-obsessed market, but the Dzire quietly keeps selling because it’s just so practical. The CNG version pairs that practicality with low running costs, and the 378-litre boot — the largest among CNG sedans — means the tank doesn’t eat into your cargo space too badly. For families who prefer the comfort of a proper three-box car, the Dzire S-CNG delivers.
9. Maruti Suzuki Ertiga S-CNG — Best 7-Seater MPV
Price: ₹8.90 to ₹10.50 lakh | Mileage: 21.0 km/kg
The Ertiga is the go-to CNG vehicle for large families and anyone who regularly carries more than five people. Seven seats, a spacious cabin, third-row AC vents, and the reliability of Maruti’s 1.5L engine make it a very complete package. At 21 km/kg, the mileage is lower than the hatchbacks on this list, but that’s expected from a bigger vehicle — and compared to petrol, the savings are still very significant.
10. Maruti Suzuki Brezza S-CNG — Best Compact SUV
Price: ₹9.25 to ₹14.50 lakh | Mileage: 21.0 km/kg
The Brezza is the most feature-packed car on this list. Connected car technology, sunroof on the top variant, 6 airbags, ESP, and that confident SUV stance — this is for buyers who want a proper compact SUV but are tired of paying high fuel bills. It’s the most expensive CNG option in the mainstream segment, but if you want everything in one package, the Brezza S-CNG delivers.

What to Consider Before Buying a CNG Car
Before you book one, here are a few things worth thinking through.
Mileage is the obvious one — look for 20 to 34 km/kg depending on your daily driving needs. Safety ratings matter more than many buyers realise — always check Global NCAP or Bharat NCAP scores. Boot space can be a real issue with older CNG systems, so check whether the model uses a twin-cylinder setup that preserves usable space. Always go for a factory-fitted S-CNG kit — aftermarket conversions can void your warranty and raise safety concerns. And check CNG availability in your city before committing; infrastructure is excellent in metros but still patchy in some smaller towns.
