Company Chairman Ratan Tata, introducing the Nano during India's main auto show, drove onto a stage in a white version of the tiny four-door subcompact, his head nearly touching the roof.
With a snub nose and a sloping roof, the world's cheapest car can fit five people - if they squeeze. And the basic version is spare: there's no radio, no passenger-side mirror and only one windshield wiper. If you want air conditioning to cope with India's brutal summers, you need to get the deluxe version.
While the price has created a buzz, critics say the Nano could lead to possibly millions more automobiles hitting already clogged Indian roads, adding to mounting air and noise pollution problems. Others have said Tata will have to sacrifice quality and safety standards to meet the target price.
The chairman, though, insists the car will meet safety standards and pollute even less than motorcycles, passing domestic and European emission standards and averaging about 50 miles per gallon.
CBS News reporter Ranjan Gupta reports the Tata empire is vast, selling everything from tea to steal across the globe.
Chief U.N. climate scientist Rajendra Pachauri, who shared last year's Nobel Peace Prize, said last month that "I am having nightmares" about the prospect of the low-cost car.
"Dr. Pachauri need not have nightmares," Ratan Tata said at the unveiling. "For us it's a milestone and I hope we can make a contribution to the country."
The basic model will sell for for 100,000 rupees - $2,500 - but analysts estimate that customers could pay 20-30 percent more than that to cover taxes, delivery and other charges.
Gupta says the Tata's chairman's intended buyer for the Nano is, "the man on a scooter who has a child on the front and his wife sitting behind."
Tata has long promised that he'd create a 100,000-rupee car, a vow that was much-derided in the global industry but created a frenzy of attention in India. On Thursday, nearly every news station covered the unveiling live.
"A promise is a promise," Tata told the crowd.
The company has said they expect the car to revolutionize the auto industry, and analysts believe the Nano may force other manufacturers to lower their own pricing. French automaker Renault SA and its Japanese partner, Nissan Motor Co., are trying to determine if they can sell a compact car for less than $3,000.
For now, the car will be sold only in India, but Tata has said it eventually hopes to export it. The Nano could become the basis for other similar super-cheap models in developing markets around the world.
As rising middle class incomes drive demand for cars in India, automakers expect the ranks of car owners in the country to expand dramatically in coming years.
But for some, a huge influx of cars is a terrifying prospect of traffic jams at midnight, hours-long commutes and increasing pollution.
"If you're talking about urban environment, it will cause serious problems," said Jamie Leather, a transport specialist with the Asian Development Bank. "It's a major concern."
In 2005, Indian vehicles released 219 million tons of carbon dioxide, the leading greenhouse gas blamed for global warming.
By 2035, that number is projected to increase to 1,467 million tons, due largely to the expanding middle-class and the expected rise of low-cost cars, according to the Asian Development Bank.
"The cheaper and cheaper vehicles become, the quicker those pollution levels will increase," Leather said.
