CNG will be an economical choice, with the only drawback being the longer waiting time at refilling stations. If that isn’t a concern, you should go for it. In your budget, the Tata Altroz iCNG is a great option, offering a twin-cylinder tank setup that provides more usable boot space than the single-cylinder setups in Maruti or Toyota CNG cars. A Hyundai Exter HyCNG Duo is also a good and efficient option for city commuting.
