The demand for a CNG vehicle has grown robustly in India. For the period of April-September 2021, data shows that 1,01,412 CNG cars were sold in the country, as opposed to 51,448 cars in the same period in 2020. This was a 97 percent y-o-y growth and a testimonial of increasing acceptance of this segment of cars among the Indian public. CNG per kilogram is also cheaper than petrol and is less susceptible to price fluctuations as well. A CNG vehicle also pollutes significantly less than a petrol/diesel car. All these factors make a CNG car an attractive buy. Here's a list of top 10 most popular CNG cars in India.
