Locomotion for $2500

Though above $2000, at $2,500 the Tata Group found a way to build the cheapest car in the world.

Tomorrow, India's biggest company will show what taking out one windshield wiper, radio, moving the engine to the back, and putting in a cheaper, hollowed out steering-wheel shaft can do to a price of an automobile.

Its impact on the environment? It is predicted to be either very positive or negative.

Update: Tata Nano a.k.a the "people's car" is out now.
