Hyundai Exter Hy-CNG Duo vs Tata Punch iCNG: Price, Features, Specifications, Mileage Compared
For the longest time, CNG car owners had to make do with a large CNG take eating up most of, if not, all of the boot space of the car. Tata, which entered the CNG market in 2022 came around with a solution to this with its dual-cylinder technology in 2023 which saw the carmaker replace the single large 60 litre water capacity CNG cylinder with two smaller units sitting under the boot floor. Currently, the carmaker’s entire CNG range is offered with the layout as standard. Now Hyundai has joined the bandwagon with the launch of the new Exter Hy-CNG Duo its first dual-cylinder CNG model.
