Among the CNG options under Rs 8 lakh, the Hyundai Exter and Tata Punch are worth a look. The Hyundai Exter CNG offers better performance than the Punch CNG, making it more suitable for highway usage. Do note, neither car feels absolutely effortless on the highway, and the lack of power is noticeable when you need to overtake.
The Punch packs in a few more features in Smart CNG trim versus an Exter 1.2 EX, which is comparable in price. There’s also a newness to the Punch that is fresh from a facelift. The Exter is due for an update of its own towards the middle of 2026.
