Top 5 Most Fuel-Efficient CNG Cars in India : With fuel prices increasing every day, more and more buyers in India are leaning toward CNG cars for better mileage and lesser running costs. Several CNG models have been introduced in 2025 by the manufacturers, which not only save fuel but also provide good comfort and good features and good performance. If you are planning to buy a car that is light on your pocket and eco-friendly, here is a list of the top five fuel-efficient CNG cars in India for 2025.
1. Maruti Suzuki Alto K10 CNG
Although it has always been a mileage champion, the Alto K10 manages to extract an impressive 33 km/kg in the CNG version. Being skillful in size, it has city driving written all over it; the small 1.0-litre engine being spirited enough that it never feels under-muscled. The low price tag and maintenance costs only put it in further favor with the budget buyer.
2. Maruti Suzuki WagonR CNG
The WagonR CNG, recognized for its tall-boy design and spacious cabin, returns around 32.5 km/kg mileage. It is powered by the same 1.0-liter K-Series engine as the Alto K10, providing better comfort and features while adding practical value for families.
3. Tata Tiago CNG
Tata’s Tiago CNG marries performance with fuel efficiency to give around 28.1 km/kg. The 1.2-litre Revotron engine feels rather strong compared to smaller CNG cars, whereas plush cabin quality and safety features like dual airbags and ABS make it a definite pick.
4. Maruti Suzuki Dzire CNG
If decent mileage is what you’re looking for in a sedan, the Dzire CNG offers a decent alternative at around 31.1 km/kg. Its 1.2-litre DualJet engine offers a tractable experience while a fairly sized boot and rear seat comfort make it an ideal candidate for both long drives and everyday city use.
5. Hyundai Aura CNG
Hyundai’s compact sedan Aura CNG offers a mileage of nearly 28 km/kg. With 1.2-litre engine displacement, stylish looks, and rich interiors, this value-for-money car does not shy away from features like an 8-inch touchscreen and rear AC vents.
