Tata Motors launches the 2013 Nano CNG emax in India

Tata Motors has launched the CNG powered version of the Nano in India. The car has been launched in two variants: CX and LX. The CX variant of the car is priced at 2.45 lakh rupees while the LX variant is priced at 2.72 lakh rupees, ex-showroom Ahmedabad. The CNG powered version of the Nano is called the emax and the car features the petrol-CNG dual fuel option. The engine of the Nano CNG is the same 624 cc, twin cylinder unit that outputs 38 PS of peak power and 51 Nm of peak torque. This engine, adapted to run on CNG, outputs 33 PS-45 Nm. The gearbox remains a 4 speed manual unit. 

To avoid intruding into the limited boot space of the Nano, engineers from Tata Motors have packaged the CNG tanks of the Nano under the front seats of the car. The Nano CNG emax's twin tanks will hold about 16 liters of CNG each, giving the Nano a range of about 150 kms on a full tank of CNG. Tata Motors claims a mileage of 36 Kms/Kg of CNG, while the tail pipe emissions, at 75.6 grams of CO2/Km, make the Nano the least emitting car in India. The 15 liter petrol tank of the Nano is retained as it is, giving the car a 375 kilometer claimed range. With petrol and CNG together, the Nano will have an effective range of 525 kilometers. 

The Tata Nano CNG emax will be sold in select markets of India, including Delhi, Maharashtra, Gujarat and parts of Uttar Pradesh. The car's factory fitted CNG kit comes with the following features:

• Sequential CNG injection
• Advanced engine management system with automatic sensors that seamlessly shift to petrol power from CNG, when the demand for more power arises. 
• Push-button type fuel selector system to switch between petrol and CNG modes
• Manual shut-off valve to stop supply of CNG
• Fire extinguisher fitted as standard on all Nano emax variants
• Leak detection sensor
• Interlock sensor that prevents CNG leakage during fueling
