Tata Motors has taken a distinctive approach in the CNG car industry by introducing dual cylinder technology in their PVs (passenger vehicles). Unlike conventional single-cylinder CNG kits, Tata’s dual cylinder system provides significantly more usable boot space, making it a practical and convenient choice for customers.
While Maruti Suzuki has long held dominance in the CNG car market in India, both Hyundai and Tata Motors have been increasing their focus on CNG vehicles and steadily growing their sales in recent years.
Tata Motors first introduced the dual cylinder technology with the Altroz CNG, which received positive feedback for its enhanced luggage-carrying capacity. Now, Tata is expanding this technology to their other models, including the Punch, Tiago, and Tigor. The official teaser confirms the upcoming launch of these CNG variants, which is highly anticipated by customers.
By offering dual cylinder CNG options in their PVs, Tata Motors is providing a practical and efficient alternative for eco-conscious buyers who value ample storage space. This move reflects Tata’s commitment to innovation and meeting the evolving needs of their customers in the competitive Indian automobile market.
More boot space than single-cylinder CNG implementation
To be fair, Maruti Suzuki also has dual cylinder CNG implementation, but they have not yet utilized it in their extensive CNG PV (passenger vehicle) portfolio. Instead, they offer dual cylinder CNG kits with their Super Carry commercial vehicle. There is a possibility that Maruti Suzuki may introduce S-CNG vehicles with two smaller cylinders in the future.
Currently, Tata Altroz i-CNG stands out as the only passenger vehicle in the country featuring this innovative dual cylinder CNG implementation. Tata has extended this technology to the newly launched Punch i-CNG, and it is also available in the updated versions of Tiago CNG and Tigor CNG. The existing Tiago i-CNG and Tigor i-CNG models come with a single large CNG tank that takes up a significant portion of the boot space, rendering it practically unusable.
The introduction of dual cylinder CNG technology in the upcoming models will solve this problem, providing a much neater and appealing CNG implementation. The two smaller tanks will be discreetly placed beneath a plastic covering, allowing for a tidier and more efficient use of boot space. This move showcases Tata’s commitment to innovation and enhancing customer experience by offering practical and space-saving solutions in their CNG-powered vehicles.

Tata Dual Cylinder CNG Tech on Tiago and Tigor – What to expect?
Tata Motors is making significant enhancements to their CNG-powered vehicles. In the upcoming models featuring the dual cylinder CNG kit, Tata will optimize the rear suspension to handle the additional weight of the CNG cylinders. To ensure efficient combustion of CNG gas, a separate ECU (Engine Control Unit) will be installed. This will enable a smooth and seamless switch between petrol and CNG fuel options, allowing drivers to choose the most suitable option as per their needs.
In terms of safety, Tata will include a mandatory fire hydrant in the cabin to provide added protection in case of emergencies. An interesting feature unique to Tata’s CNG cars is the ability to start the engine on CNG fuel, which sets them apart in the market.
Under the hood, the dual cylinder CNG kit will be paired with the same 1.2L 3-cylinder NA (naturally aspirated) petrol engine. The power and torque output of the outgoing CNG powertrain will remain unchanged, with 72 bhp and 102 Nm on CNG and 87 bhp and 115 Nm on petrol. The gearbox will be a 5-speed manual unit, providing a smooth and efficient driving experience.
With the introduction of the dual cylinder CNG technology, Tata Motors is offering customers a practical and eco-friendly solution with minimal impact on engine performance. While exact pricing details for the Punch CNG model are yet to be announced, it is expected that there will be a reasonable price increase compared to the petrol-powered variant, similar to what was seen with the Altroz i-CNG.
