"The India business is loss- making right now, which is unsustainable for the company," said Kapil Singh, an analyst with Nomura Holdings in Mumbai. "The Nano has not met expectations so models such as the diesel Nano will help, but we'll have to watch where they price it at."
Slym plans to "dramatically" change customer focus to revive demand for the Nano, whose sales plunged and never fully recovered after at least three caught fire in 2010.
Instead of seeking to sell to motorcycle owners looking to upgrade, the company will market the car to customers "aspiring" to buy the Nano, said Slym, who joined from GM's China unit.
Ratan Tata decided to develop the Nano after seeing a family riding on a scooter. After the fires, the company in December 2010 extended warranties to four years or 60,000 kilometres and started offering as much as 90 per cent financing through unit Tata Motors Finance.
Sales of the Nano plunged 81 per cent to 1504 units in January from a year earlier after peaking at 10,475 units in March 2012.
The company chose the first 100,000 customers for the Nano through a lottery following a deluge of orders in 2009.
