The company claimed the Nano Twist is the first in the category to have an electric power steering as all other manufacturers like Maruti offer only hydraulic power steering.
The Nano Twist is priced at Rs 1.55 lakh to Rs 2.36 lakh, the company said, adding that it will continue to roll out the existing models.
The company is planning to take the Nano to two more markets outside the country, the details of which will be announced soon, said Ankush Arora, senior VP for marketing and sales, passenger vehicles division at Tata Motors.
On the rationale for launching the Nano Twist with a power-steering now and not a diesel model, Arora said consumer preferences have changed and the company wants to offer the Nano as "a wholesome package."
It can be recalled that all these years the company had been maintaining that the Nano does not require a power steering as its engine is fitted in the rear.
The Nano Twist comes with the rear-mounted 600cc in petrol engine.
Arora refused to talk on the media reports about an 800-cc engine. He also refused to offer a time-line for the proposed diesel model.
On how the Nano is doing in the export markets Nepal and Sri Lanka, Arora said in Sri Lanka it sells around 200 units a month, while in the Himalayan country it is only about 30 units.
On the CNG model, he said it is doing extremely well especially in those markets where the fuel price has come down like Ahmedabad but has shown some fall in those markets where the price has gone up.
