The Nano CNG will be powered by the same 624cc MPFI petrol unit, which will be retuned to work with CNG or Petrol Bi-Fuel configuration. It will also feature the same transmission and suspension settings as the Nano petrol variant. However, the suspension setting will be slightly re-tuned to account for the extra weight of the CNG variant, which stands at 710kg as compared to the regular Nano that weight 600kg.
The Tata Nano CNG concept featured at Auto Expo was equipped with a 15-litre petrol tank with a 35-litre capacity CNG cylinder. We expect the production version to carry the same configuration of petrol and CNG capacity. The company claimed mileage is 35kmpl.
The CNG kit will feature a high-tech switchable Bi-fuel Petrol-CNG fuel system with sequential gas injection system with calibrated EMS that allows for smart switching between CNG and petrol. This system is also able to cut off CNG, in case a leakage is detected. The company claims that the kit will be installed intelligently, so as to not compromise the luggage space inside.
On the price front, the Nano CNG is expected to cost about 15 to 20 per cent more than the Tata Nano petrol.
