Owing to the lower running cost of compressed natural gas (CNG) vehicles in comparison to gasoline operated vehicles, the increasing cost of CNG is unlikely to affect the sales of CNG powered passenger and commercial vehicles. Prices of CNG as well as petrol and diesel have been on a hike since the beginning of the year. Despite this, CNG remains nearly 30 per cent cheaper than petrol and diesel. Moreover, CNG stations have been increasing and network has been expanding in the country rapidly.
