A key advantage is Hyundai’s dual-cylinder CNG setup, which improves boot usability compared to older single-cylinder CNG layouts. The Exter also offers a more SUV-like seating position and a feature-rich cabin.

Other CNG Cars Worth Considering
There are plenty of excellent CNG vehicles that do not appear on the higher fuel economy list because they are larger than other vehicles. Large CNG vehicles may have somewhat lower fuel economy, but they have much more room, seating, and practical usage than the smaller hatchback-style vehicles.
| CNG car | Claimed mileage | Why consider it |
| Tata Punch CNG / Punch CNG AMT | Around 26.99 km/kg | Twin-cylinder layout and SUV-like stance |
| Tata Altroz CNG / Altroz CNG AMT | Around 26.90–27.80 km/kg | Premium hatchback with CNG AMT option |
| Maruti Suzuki Victoris CNG | 27.02 km/kg | Larger SUV option with CNG |
| Maruti Suzuki Grand Vitara CNG | Around 26.60 km/kg | Midsize SUV CNG option |
| Maruti Suzuki Ertiga CNG | 26.11 km/kg | 7-seater family MPV |
| Toyota Rumion CNG | 26.11 km/kg | 7-seater Toyota-badged MPV |
| Maruti Suzuki Brezza CNG | 25.51 km/kg | Compact SUV with factory CNG |
Thus, these types of vehicles are ideal for someone who requires more space or a larger vehicle than would be available from a standard small hatchback.
CNG Manual vs CNG AMT: Which Is Better?
Most CNG cars in India still come with manual gearboxes, but Tata has made CNG AMT options more accessible in cars like the Tiago, Tigor, Punch and Altroz. But should you consider investing in them?
| Factor | CNG manual | CNG AMT |
| Purchase cost | Usually lower | Usually higher |
| City convenience | Lower | Better |
| Mileage | Often slightly better or similar | Depends on model and driving style |
| Availability | Wider | Limited to select Tata models |
| Best for | Budget-focused buyers | Traffic-heavy city users |
Choose the CNG manual if your priority is lower purchase cost. Choose CNG AMT if you drive in traffic every day and want easier city driving.
Final Verdict
If your only priority is maximum mileage, the Maruti Suzuki Celerio CNG is the strongest pick with a claimed mileage of 34.43 km/kg. If you want a sedan, the Maruti Dzire CNG is one of the most efficient options at 33.73 km/kg. If you want a practical city hatchback, the Wagon R CNG remains a strong choice.
For those who need something beyond mileage, there are different choices. The Baleno and Glanza provide a higher level of hatchback experience compared to the Fronx, Taisor and Exter, which provide SUV-like features. In the Tata line-up, Tiago, Tigor, Punch and Altroz use different transmission technologies in a twin-cylinder layout.
So, choose a small Maruti CNG hatchback for the highest mileage, a Tata CNG AMT for city convenience, and a larger CNG SUV or MPV if space matters more than the highest mileage number.
