The models that are likely to be phased out are Nano, Indica, Indigo CS and Sumo. The company plans to develop new models based only on the two platforms instead of the present six.

As per ET Auto, Tata Motors marketing head (passenger vehicle business) Vivek Srivastava confirmed that currently, Tata Motors has ten cars in their portfolio including the newly launched Tigor. The company will launch at least four new vehicles without increasing the size of the product range; this means phasing out of some of the existing vehicles.

The Tata Nano has been in the news in recent times with dismissed Tata Sons chairman Cyrus Mistry stating that the Nano's production should be stopped to prevent the company's loss.

The phaseout is not just vital; it is also partly necessary as new safety norms that require crash test and BS 4 emission regulations which kick in from 2018 and 2020 respectively.

The company has not been able to phase out Indica and Indigo CS as they continue to bring in numbers in the commercial segment. Once these are removed, Bolt and Zest will be the offering to fleet buyers.

Removing older vehicles from Tata Motors' portfolio and launching new ones are crucial to Tata Motors as it looks to grab the third spot among Indian automakers.

Among the new launches lined up in 2017-18 is the compact SUV Nexon, showcased at the Indian Auto Expo, and the sports car TaMo Racemo that was revealed at the 2017 Geneva Auto Show.
