That's the point! CNG era has finished, now for a car to win the market, it has to super fuel efficient like this one. If this is the average, (25 kmpl) then you'll only need 10 litres to cover 250 km distance which costs just 7660 Rupees at the moment!
If your daily urban commute is 35 km or less, you'll only need 2 litres to complete your trip. This car can beat any European hatchback because those cars have to meet strict EU emission standards which sometimes proves costly in terms of car price and regular maintenance cost.
