Tata Motors has started to sell what it calls "the world's cheapest car", designed to appeal to the Indian market.
The Nano was launched at a ceremony in Mumbai, India's financial capital, on Monday.
It is being promoted as a car that will enable people in developing countries to trade up to four wheels.
The 3.1-metre-long car, priced at 100,000 rupees (about $2,000), is a four-door, five-seater vehicle with a two-cylinder 623cc engine and a top speed of 105kmph.
The basic model comes without air conditioning, electric windows or power steering, though the company has said deluxe versions will be available.
'Safer' alternative
Ratan Tata, the chairman of Tata Motors, has said he created the car to help Indian families stop using unsafe motorcycles.
"I observed families riding on two-wheelers, the father driving the scooter, his young kid standing in front of him, his wife seated behind him holding a little baby," Tata said while unveiling the prototype in 2008.
"It led me to wonder whether one could conceive of a safe, affordable, all-weather form of transport for such a family."
Critics say the Nano could clog India's already crowded streets and add to pollution.
Rajendra Pachauri, the head of the United Nations' climate panel, said: "Every car that goes on the road is going to use road space. We're only adding to congestion."
Tata has dismissed fears the cheap car would bring more congestion and pollution, arguing the car would be better and far safer than most motorcycles on India's roads.
Delayed debut
The launch has come six months late, it was due in October 2008, following months of violent protests over the acquisition of farmland for the project.
The protests prompted the motor company to move its Nano factory from India's West Bengal state to Gujarat, a state considered more business-friendly.
But company officials have said it will take at least a year to complete the new factory, so Tata will only be able to produce a limited number of Nanos from its other plants in India.
