A Company To Watch

India's Tata Group has unveiled the worlds cheapest car. 100,000 rupees or about 2,500 dollars.

Environmentalists fear the Nano will jam up India's already clogged roads even more and add to choking pollution if it proves a winner.

"With more cars you have more emissions and that adds to global warming -- what we need is public transport," said Souparno Banerjee, an official of Delhi's Centre for Science and Environment.

Not much you can do about congestion but this is the company that has teemed up with the air compressed engine company from France. It looks like a very similar vehicle.
