Snapshot – CNG is a clean burning fuel that is cheaper than both petrol and diesel. Cars powered thus are getting very popular in cities where Compressed Natural Gas dispensing infrastructure is well developed. If your prime concern is low running costs within the city, a CNG powered car makes a lot of sense. Highway use isn’t a problem too as all the cars that use CNG are dual fuel versions, which means that they also run on petrol. CarToq puts together the entire list of cars powered by compressed natural gas in India.
Tata Nano E-MAX
The Tata Nano is the world’s least priced car, and this also applies to its CNG variant. Dubbed the Nano E-MAX, the gas powered variant of the car delivers a whopping 36 kilometer mileage per Kg of CNG, making for running costs of 1.05 rupee per kilometer, stuff that can challenge 100cc commuter motorcycles. The car stores the compressed natural gas in toroidal, space saving cylinders mounted under the front seats. The 624cc engine of the Nano manages to output 32 Bhp-45 Nm while running on CNG, lower than the 37 Bhp-51 Nm figures while running on petrol.
