Tata Motors has become the first Indian manufacturer to introduce automatic transmission in the CNG segment. It has introduced Tiago and Tigor CNG models with AMT and bookings for the new variants have been opened opened for a token amount of INR 21,000. Tata Tiago iCNG AMT will be available in three variants – XTA CNG, XZA+ CNG and XZA NRG while the Tata Tigor iCNG AMT will be available in two variants – XZA CNG and XZA+ CNG.
New colours introduced
The manufacturer has also introduced new Tornado Blue colour on Tiago, Grassland Beige on Tiago NRG and Meteor Bronze on Tigor.
Feature highlights
Both Tiago and Tigor CNG models come with twin-cylinder CNG tanks, placed below the luggage compartment to ensure that the boot space is not compromised. The single advanced ECU ensures jerk-free shifting between petrol and CNG modes while Direct CNG start option allows drivers to start the car directly in CNG mode. The cars are powered by 1.2L Revotron Engine.
Safety highlights
Safety features on the Tiago and Tigor CNG models include micro switch to keep the car switched off at time of refueling, thermal incident protection technology immediately cuts off CNG supply to the engine in case of a thermal incident and releases gas from the cylinder directly into the atmosphere through a special nozzle. The location of the twin CNG cylinders offer a safe solution as the valves and pipes are protected under the load floor, minimizing the risk of potential damage.
Additionally, the manufacturer has used advance materials in iCNG kit to prevent leakage while the kit itself has been tested across temperatures and pressures to prevent any gas leaks. Thanks to the leak detection feature, the car immediately detects a gas leak and switches from CNG to petrol mode.
