Hyundai recently introduced the dual-cylinder technology for the Exter CNG, becoming only the second manufacturer in India to offer this tech. The Exter CNG directly rivals the Tata Punch CNG while also competing with the CNG versions of the Maruti Fronx and the Toyota Taisor. Here’s a detailed spec comparison of the Exter CNG with the other three.

Hyundai Exter CNG vs rivals: dimensions

While all these SUVs get a 1.2-litre NA petrol engine, the Punch’s unit has three cylinders instead of four like its rivals. In CNG mode, the badge-engineered siblings’ engine produces 78hp – making them the most powerful CNG SUVs in this comparison. The Punch CNG is the torquiest offering. All models have a 5-speed manual transmission as standard.

The Exter CNG and Punch CNG are the only SUVs in India with a dual-cylinder setup, which helps free up boot space. Conventional CNG cars have a single, larger cylinder.

Hyundai Exter CNG vs rivals: price

With a starting price of Rs 7.23 lakh, the Tata Punch CNG is the most affordable CNG SUV in India, followed by Maruti Fronx (Rs 8.46 lakh), Hyundai Exter (Rs 8.50 lakh) and Toyota Taisor (8.71 lakh). The range-topping Punch CNG variant will set you back by Rs 9.85 lakh, which also makes it the most premium offering here.
