New Delhi: The popular compact sedan from Tata Motors, the Tigor is now available with the I-CNG option. Interestingly, Tata is also the first manufacturer to offer a CNG option in the top-spec variant. The Tigor i-CNG is available in both the XZ and XZ+ variants. Apart from this, the i-CNG option could also be on the dual-tone XZ+ variant. The compact sedan is now available in other color options like Daytona Grey, Opal White, Arizona Blue and Pure Silver apart from the new Magnetic Red color option.
The company claims that the i-CNG unit uses high quality stainless-steel tubes and fittings, and has also been tested under high temperature and pressure to prevent gas leakage. Once the fuel lid is opened, the micro switch turns off the ignition and prevents the vehicle from operating until the lid is securely closed.
In the event of a thermal incident, Thermal Incident Protection shuts off the supply of CNG to the engine, and releases the gas into the atmosphere from the cylinder through a special nozzle. Also, the system is capable of automatically switching from CNG to Petrol mode in case of a gas leak. Under the pillion seat, the company provides a fire extinguisher for added protection.
