With petrol and diesel prices showing no signs of slowing down, CNG has emerged as the go-to option for budget-conscious car buyers in India. While CNG variants usually cost more than their petrol counterparts, the lower running costs make them a smart choice for everyday urban driving. Several manufacturers are now offering factory-fitted CNG kits across hatchbacks, sedans, and compact SUVs.
If you’re planning to buy a CNG car and fuel efficiency is your top priority, here’s a look at the top 10 cars in India that deliver the highest claimed mileage on CNG – ranked from the least to the most efficient.
10. Tata Punch CNG
Price: ₹7.30 lakh – ₹10.17 lakh
Tata’s popular micro-SUV gets the brand’s twin-cylinder CNG setup, which frees up more boot space than traditional kits. Powered by a 1.2-litre, 3-cylinder engine, the Punch CNG returns a claimed 26.99 km/kg. It comes with a 5-speed manual gearbox but misses out on the AMT option available in the petrol version.
9. Hyundai Exter CNG
Price: ₹7.51 lakh – ₹9.53 lakh
Hyundai’s smallest SUV brings practicality with both single- and dual-cylinder CNG options across multiple trims. Under the hood is a 1.2-litre, 4-cylinder petrol engine producing modest power but impressive efficiency, delivering 27.10 km/kg with a 5-speed manual gearbox.
8. Maruti Suzuki Fronx / Toyota Urban Cruiser Taisor CNG
Price: ₹8.54 lakh – ₹9.40 lakh (Fronx) | ₹8.87 lakh (Taisor)
These badge-engineered siblings share the same 1.2-litre, 4-cylinder CNG-compatible engine paired with a 5-speed manual. Both manage a frugal 28.51 km/kg. While the Fronx offers multiple trims, Toyota offers the Taisor CNG in a single variant.
7. Maruti Suzuki Baleno / Toyota Glanza CNG
Price: ₹8.48 lakh – ₹9.41 lakh (Baleno) | ₹8.81 lakh – ₹9.80 lakh (Glanza)
Another Maruti-Toyota duo, these premium hatchbacks are among the most fuel-efficient in their class. Equipped with the familiar 1.2-litre, 4-cylinder engine, they return 30.61 km/kg. Both are available only with a 5-speed manual gearbox.
6. Maruti Suzuki S-Presso CNG
Price: ₹5.92 lakh – ₹6.12 lakh
The quirky-looking hatchback is not only one of the most affordable cars in India but also highly frugal. Its 1.0-litre, 3-cylinder engine promises 32.73 km/kg, making it a solid choice for city driving on a budget.
5. Maruti Suzuki Swift CNG
Price: ₹8.20 lakh – ₹9.20 lakh
The new-generation Swift introduces a 1.2-litre, 3-cylinder petrol engine with factory-fitted CNG. The result? An impressive 32.85 km/kg efficiency. Available in mid and top trims, it combines style, practicality, and economy.
4. Maruti Suzuki Dzire CNG
Price: ₹8.79 lakh – ₹9.89 lakh
The Dzire is the only sedan in this list, offering more boot space than its hatchback sibling, the Swift. Despite the extra size, its 1.2-litre, 3-cylinder engine manages 33.73 km/kg, making it the most efficient CNG sedan currently on sale.
3. Maruti Suzuki Alto K10 CNG
Price: ₹5.90 lakh – ₹6.21 lakh
India’s most affordable small car also ranks among the top three in fuel efficiency. Its lightweight build and 1.0-litre engine help it achieve 33.85 km/kg, making it a popular pick for budget buyers.
2. Maruti Suzuki Wagon R CNG
Price: ₹6.69 lakh – ₹7.13 lakh
The tallboy Wagon R has long been a favorite among CNG buyers. It offers good cabin space, practicality, and now, a class-leading 34.05 km/kg efficiency from its 1.0-litre, 3-cylinder engine.
1. Maruti Suzuki Celerio CNG
Price: ₹6.90 lakh
At the top of the charts is the Celerio, which outshines even smaller cars with a remarkable 34.43 km/kg mileage. Despite being larger than the Alto K10 and S-Presso, it makes the most efficient use of its 1.0-litre engine. The CNG variant is offered in a single mid-spec trim.
Conclusion
With diesel options shrinking in the small car segment, CNG models are filling the gap by offering significantly lower running costs without compromising much on practicality. From hatchbacks like the Alto K10 and Celerio to compact SUVs like the Punch and Exter, there’s now a CNG car for almost every type of buyer.
If maximum mileage is your top priority, the Maruti Suzuki Celerio remains the undisputed king of fuel efficiency in India.
