Increasing petrol prices and the push towards cleaner mobility have brought multiple alternate fuel vehicles in India, however, some automakers, especially Maruti Suzuki, Hyundai, and Tata Motors have kept their ICE engines but tweaked them to run on alternate fuel.
One that has seen immense success is CNG, as the number of vehicles that run on Compressed Natural Gas has seen an increase. Also, enabling a petrol car to run on CNG is cost-effective for carmakers when compared to other options. Here are the top 5 CNG vehicles in India with the best mileage one can buy.
