Seven months after the launch of Nano, Tata Motors is toying with the idea of letting local garage assemblers put together the world’s cheapest car and also sell it under a brand of their own.

The company, which is revisiting the concept of distributed manufacturing mooted by Chairman Ratan Tata when he first talked of the Rs 1 lakh car several years ago, will become the world’s first to attempt such a “federal” structure of manufacturing.

Speaking at The Economist Innovation conference in London on Friday, Tata Motors Vice-Chairman and former managing director Ravi Kant said with the new Nano plant likely to start commercial production in the last quarter of this financial year ending March 2010, the company may allow enterprising assemblers to set up micro-assembly sites across the country, with each producing some 10,000 cars a year.

Ravi Kant”We call it Nano, they (assemblers) don’t have to,” said Kant, who received the The Economist Innovation award 2009 (for business process) on behalf of Tata for developing and rolling out the world’s cheapest car.

Experts, however, said handing over the branding power to small assemblers may not be easy. For one, the perceived and actual safety of a car has always been associated with the brand.

Tata Motors will have to be extra careful about safety concerns after a small number of Nanos sold in India reported technical problems last month, forcing the company to conduct a preemptive audit of the quality of cars already shipped as well as those in the inventory.

“The Indian car market has still not come to this stage. Given that a car like Nano is three or four year’s investment, customers will still go for established brands from strong OEMs (original equipment manufacturers; in this case Tata Motors). So this idea may not fly very well,” said Abdul Majeed, leader, automotive practice, with PricewaterhouseCoopers in India. There would also be concerns about after-sales services and spare parts, he added.
