Pricing & specs disclaimer: The prices, mileage and specifications mentioned in this article are indicative and may not be fully accurate or up to date. Always verify the latest figures from the official Maruti Suzuki website or an authorised dealer before making a purchase decision.
As petrol prices stay stubbornly high and the government accelerates its push towards a cleaner, gas-based economy, one fuel keeps winning over India's value-conscious buyers — CNG. And no carmaker has embraced it like Maruti Suzuki. With its factory-fitted S-CNG range spanning hatchbacks, sedans, SUVs and MPVs, Maruti doesn't just compete in the CNG space — it defines it. Here's the full Maruti CNG line-up for 2026, with mileage, pricing and our pick of the best.
Why CNG, and why now?
CNG (compressed natural gas) costs far less per kilometre than petrol or diesel, burns cleaner, and — thanks to the government's expanding City Gas Distribution network — is reaching more cities and highways every year. For a country chasing both lower fuel bills and lower emissions, it's a natural fit. The government's stated goal of raising the share of natural gas in India's energy mix has put real momentum behind CNG, and Maruti has been the industry's most committed partner in that shift, selling over half a million CNG vehicles a year.
Why Maruti leads India's CNG market
- The widest range. No rival comes close to Maruti's spread of factory CNG models — from the entry Alto K10 to the Ertiga MPV.
- Factory-fitted S-CNG. Integrated and tested by Maruti with dual independent injection and safety systems — far safer and more reliable than an aftermarket retrofit, and fully warranty-backed.
- Class-leading efficiency. Maruti's light, frugal engines are ideal for CNG, delivering the lowest running cost per kilometre in India.
- Service and resale. The country's largest service network and strongest resale values apply to the CNG cars too.

Our top picks
Best overall value: Maruti WagonR S-CNG
The tall-boy WagonR is the CNG sweet spot — roomy, easy to drive, with a claimed 34 km/kg and a sensible price. For a family wanting the lowest running cost without compromising practicality, nothing makes more sense.
Best mileage: Maruti Celerio S-CNG
With a claimed figure of around 34.43 km/kg, the Celerio is among the most fuel-efficient cars on sale in India, full stop. It's the thrifty commuter's dream.
Best for families: Maruti Ertiga S-CNG
A genuine 7-seater that runs on CNG is a rare thing, and the Ertiga does it brilliantly. For large families and ride-hailing operators chasing the lowest cost-per-seat, it's in a class of one.
Best SUV style: Maruti Fronx / Brezza S-CNG
Want SUV looks and CNG savings? Maruti is one of the very few brands offering factory CNG on stylish compact SUVs, letting you have the higher stance without the higher fuel bill.
Rivals offer a CNG model or two. Maruti offers a CNG car for almost every kind of buyer — and backs each one with the cheapest servicing and strongest resale in the country. That's why it owns this market.
CNG running-cost advantage
Here's the maths that wins buyers over. At a typical CNG price and an efficiency of around 30 km/kg, a Maruti S-CNG car can cost roughly half as much per kilometre to run as the equivalent petrol model. Over 15,000 km a year, those savings add up to a meaningful sum — often recovering the CNG variant's small price premium within the first 12–18 months. After that, it's money straight back in your pocket.
Pros and cons of a Maruti CNG car

Verdict

As the government continues to expand the gas network and back cleaner fuels, Maruti's early, wholehearted bet on CNG looks more far-sighted than ever. For value-focused buyers, this is exactly where the smart money goes.
