Best mileage CNG cars in India in 2025

CNG technology has come a long way in recent years, leading to some impressive mileage results. Let us talk about the highest mileage CNG cars in India in 2025 and take a look at what's good, what's not and how they fare against each other.

CNG powered cars have many advantages, they can extend the total distance a car can travel as this fuel type has a separate storage unit, enabling the cars to run either on petrol or CNG, as required. When the car is running on petrol, the engine works as it should, the injectors spray the air-fuel mix into the cylinders and the combustion cycle proceeds normally. But, when the car is shifted to CNG, the injectors are shut off, disabling any petrol from entering the combustion chamber. Instead, CNG is added into the engine through the intake, powering the car completely on the alternate fuel.

Moving on to the stars of the show, the table below displays the top contenders for the best mileage CNG cars in the Indian market today.

Benefits of opting for CNG powered cars

CNG cars are mostly beneficial for people who have long commutes on a daily basis. Not only is CNG cheaper than petrol or diesel, it also runs longer per unit of fuel consumed. But that doesn’t mean that if you don’t have long commutes it isn’t beneficial for you. Even with shorter distances, CNG does better than other fuel types. Check out the CNG Kit Price in India.
Reduction in fuel costs: The gas primarily used for the production of CNG, i.e. methane, is extracted and compressed using a cheaper and simpler process. As a result, it is a much lower-priced fuel option than petrol or diesel. By opting for a CNG-powered car instead of a petrol or diesel one, you may be able to save approximately 40% in monthly fuel costs.
Better Mileage: Technological advancements in the automobile industry have led to better mileages for CNG cars than their petrol or diesel counterparts. The mileage of a CNG car ranges from 26-31 km/kg, which means that on a full tank, it can average between 180-340 km, depending on the size of the storage cylinder and the car’s engine.

The future of CNG cars looks promising. The industry is also continuously making technological advancements that are further enhancing what these cars can offer.
