CNG is increasingly becoming the fuel of choice for budget car buyers, amidst petrol and EV counterparts, thanks to many automakers pulling the plug on small-capacity diesel engines. Maruti Suzuki has been dominating the CNG market in India with a wide range of models, which is followed by the latest-entrant Toyota, along with Hyundai and Tata vying for a piece of the pie.
CNG vehicles do command a premium over their petrol counterparts, but have significantly lesser running costs, making it viable for use in the city. So, here’s a list of all CNG vehicles currently on sale in India, ranked from the least to the most fuel efficient, offering a cheaper and cleaner alternative to petrol and diesel. However, it’s worth noting that in November 2022, the price of CNG reached an all-time high of Rs 89.5 per kg in Mumbai.
10. Tata Tiago CNG, Tigor CNG - 26.49km/kg
Launched back in January this year, the Tiago and Tigor are the first cars from Tata Motors to receive the CNG treatment. Both the hatchback and the compact sedan are powered by the same 1.2-litre, three-cylinder engine, which is offered only with a 5-speed manual gearbox. Their power output is also identical with both producing 73hp and 95Nm in CNG mode and 86hp and 113Nm in petrol mode. Tata is offering the CNG kit on all trims of the Tiago – from the base XE to the top-spec XZ+ trim – whereas the Tiago receives it only from the mid-spec XM to the top-spec XZ+ trim.
Prices for the Tiago and Tigor range between Rs 6.35 lakh-7.90 lakh and Rs 7.45 lakh-8.84 lakh (ex-showroom, India), respectively, costing Rs 90,000 more than their equivalent petrol trims. Tata claims a fuel economy of 26.49km/kg for both models, which is admittedly some way off its rivals.
9. Hyundai Aura CNG - 28.4km/kg
The Hyundai Aura is the next CNG-powered compact sedan on sale in the country, which is powered by a 1.2-litre, four-cylinder engine that’s paired to a 5-speed manual gearbox. This engine, which is shared with the Grand i10 Nios CNG, produces 69hp and 95.2Nm in CNG mode and 83hp and 115Nm in petrol mode. The CNG versions are only offered with a 5-speed manual gearbox.
Hyundai claims a fuel economy of 28.4km/kg for the Aura CNG, which is only marginally lesser than the Nios CNG. Hyundai offers the CNG kit on the S and SX trims of the Aura. Prices of the Aura CNG start at Rs 7.88 lakh, going up to Rs 8.57 lakh (ex-showroom, Delhi) costing Rs 95,000 more than the equivalent petrol trims.
8. Hyundai Grand i10 Nios CNG - 28.5 km/kg
As the hatchback sibling of the Hyundai Aura, the Grand i10 Nios remains to be one of the more premium and feature-equipped CNG cars you can currently buy. Hyundai offers the CNG kit on the hatchback in the Magna, Sportz and Asta trims.
As mentioned before, the Grand i10 Nios CNG is powered by the same 1.2-litre, four-cylinder powertrain as on the Aura CNG, producing identical power outputs. However, the hatchback offers a marginally better claimed fuel economy of 28.5km/kg. Prices for the Grand i10 Nios CNG range between Rs 7.16 lakh-8.45 lakh (ex-showroom, Delhi).
7. Toyota Glanza, Maruti Suzuki Baleno CNG - 30.61km/kg
Toyota and Maruti Suzuki recently launched the Glanza and Baleno CNG, making them the only premium hatchbacks so far to be equipped with a factory-fitted CNG kit. The Glanza is the brand’s first ever CNG model in the market whereas the Baleno is the first CNG model from Maruti’s Nexa model line-up. Both premium hatchbacks are powered by the same 1.2-litre, four-cylinder engine that’s paired only to a 5-speed manual gearbox, producing 90hp and 113Nm in petrol mode and 77hp and 98.5Nm in CNG mode.
Maruti Suzuki and Toyota both offer the Glanza and Baleno CNG in two trims – S and G for the Glanza and Delta and Zeta for the Baleno. The Baleno CNG undercuts the Glanza CNG in terms of price as the former ranges between Rs 8.28 lakh-9.21 lakh whereas the latter ranges between Rs 8.43 lakh-9.46 lakh (ex-showroom, Delhi). Both models cost Rs 95,000 more than their equivalent petrol-powered versions.
6. Maruti Suzuki Swift CNG - 30.90km/kg
Launched in August this year, the Swift CNG is one of the latest models in Maruti’s line-up to be offered with a factory-fitted CNG kit. It is powered by a 1.2-litre, 4-cylinder engine that’s paired to a 5-speed manual gearbox, which produces 77hp and 98.5Nm in CNG mode and 90hp and 113Nm in petrol mode. This not only makes it the most powerful, but also more efficient than its rivals, the Hyundai Grand i10 Nios (28.5km/kg) and Tata Tiago (26.49km/kg).
The Swift CNG is available in the VXi and ZXi trims, and is priced from Rs 7.77 lakh-8.45 lakh (ex-showroom, Delhi).
5. Maruti Suzuki Dzire CNG - 31.12km/kg
Launched back in March this year, the Dzire is the third compact sedan in the market to get a CNG version. The Dzire CNG shares the same 1.2-litre, four-cylinder powertrain as the CNG versions of the Baleno, Swift and Glanza. This means that it produces 90hp and 113Nm in petrol mode and 77hp and 98.5Nm in CNG mode. Similar to its hatchback counterpart, the Swift, the Dzire CNG is available in two trims – VXi and ZXi. Prices of the Dzire CNG range between Rs 8.23 lakh-8.91 lakh (ex-showroom, Delhi) making it Rs 95,000 more than the equivalent petrol trims.
4. Maruti Suzuki S Presso CNG - 32.73km/kg
Maruti launched the CNG version of the updated S Presso earlier this month, further expanding its CNG model line-up. The S Presso CNG also gets the new 1.0-litre K10C engine that’s only offered with a 5-speed manual gearbox. In petrol-only mode, the engine puts out 65hp and 89Nm of torque, which drops to 57hp and 82Nm in CNG mode. Similar to other Maruti Suzuki CNG models, the S Presso is also available in two trims – LXi and VXi. Prices of the S Presso CNG range between Rs 5.90 lakh-6.10 lakh (ex-showroom, Delhi), which, again, is Rs 95,000 more than the equivalent petrol trims.
3. Maruti Suzuki Alto K10 CNG - 33.85km/kg
As the 13th CNG model in the brand’s line-up, the Alto K10 CNG gets the same 1.0-litre K10C engine from the S Presso CNG with identical power outputs as the latter. Maruti claims that the new Alto K10 CNG can offer a fuel economy of 33.85km/kg, making it the third most fuel efficient CNG-powered car in the market. The brand has also recalibrated the suspension set-up of the Alto K10 CNG in order to enhance its overall ride quality, comfort and safety.
Maruti is offering the Alto K10 CNG in a sole VXi trim at a price tag of Rs 5.95 lakh (ex-showroom, Delhi), which is Rs 95,000 more than its equivalent petrol trim.
2. Maruti Suzuki Wagon R CNG - 34.05km/kg
Maruti Suzuki updated the Wagon R back in February this year by introducing some equipment updates and the more fuel efficient 1.0-litre and 1.2-litre petrol engines. However, CNG buyers can only get the factory fitted kit with the 1.0-litre unit that’s paired to a 5-speed manual gearbox. This engine develops 65hp and 89Nm in petrol mode and 57hp and 82.1Nm in CNG mode. The Wagon R CNG is also available in two trims – LXi and VXi – with prices ranging between Rs 6.43 lakh-6.86 lakh (ex-showroom, Delhi), and costs Rs 95,000 more than its equivalent petrol trims. This makes the Wagon R the second most fuel efficient hatchback in the country.
1. Maruti Suzuki Celerio CNG - 35.60km/kg
The Celerio CNG, which was launched back in January this year, continues to hold the distinction of being the most fuel-efficient CNG vehicle in India. The budget hatchback is powered by the same 1.0-litre K10C DualJet engine as the S Presso CNG with identical power outputs. However, the brand offers the Celerio CNG only on the mid-spec VXi trim for Rs 6.69 lakh (ex-showroom, Delhi) – Rs 95,000 more than its equivalent petrol-powered counterpart.
