What defines the perfect CNG car today? If your answer is “just mileage,” it’s time to rethink. While fuel efficiency remains important, customer expectations have evolved. Buyers now seek a complete package that balances performance, practicality, safety, and convenience — not just low running costs.
Hyundai Motor India has been quick to recognize this shift. Their Hy-CNG Duo variants reflect this vision, offering a well-rounded CNG solution with enhanced usability. The key term here is Duo — referring to Hyundai’s twin-cylinder CNG setup that brings added convenience over traditional single-cylinder layouts.
The Hyundai Exter, equipped with this Hy-CNG Duo tech, stands out as the most thoughtfully designed CNG SUV in the B-segment space. Here’s why it sets a new benchmark.
Hyundai Exter Hy-CNG Duo
If we take a closer look at the B-SUV segment, it’s clear that several contenders offer CNG powertrains. However, the Hyundai Exter Hy-CNG Duo sets itself apart by delivering the most complete CNG package in this space. It pairs a refined and capable powertrain with Hyundai’s intelligent twin-cylinder CNG storage solution, offering buyers enhanced practicality without compromising on boot space or usability.

When it comes to fuel efficiency, the Exter Hy-CNG Duo shines with an impressive 27.1 km per kg of CNG. This stellar mileage makes it a strong alternative to diesel-powered vehicles, significantly reducing running costs and offering long-term savings—perfect for cost-conscious urban commuters and long-distance drivers alike.
Best CNG Package
What sets the Hyundai Exter Hy-CNG Duo apart as the best CNG package in India’s B-SUV segment is Hyundai’s thoughtful and well-engineered approach to CNG mobility. In this segment, there are currently two rival OEMs offering factory-fitted CNG options—one combines a dual-cylinder CNG kit with a 3-cylinder engine, while the other provides only a single-cylinder CNG setup.
Hyundai takes a smarter route. The Exter Hy-CNG Duo is the only B-SUV in the country to pair a refined 4-cylinder 1.2L Kappa engine with a space-efficient dual-cylinder CNG system. This engine is known for its smooth and vibration-free performance, and when combined with Hyundai’s twin-cylinder storage solution, it ensures minimal compromise on boot space—making it a more practical and premium CNG choice for Indian buyers.

The combination of Hyundai’s smooth and refined 4-cylinder 1.2L Kappa engine with a practical dual-cylinder CNG setup makes the Exter Hy-CNG Duo the most well-rounded CNG offering in the B-SUV segment. This setup not only delivers a superior driving experience but also retains usable boot space—an area where many rivals fall short. Add to that Hyundai’s strong reputation for reliability, low maintenance costs, and hassle-free ownership, and the Exter Hy-CNG Duo becomes a smart, peace-of-mind purchase for today’s value-conscious SUV buyer.
