There is a lot riding on its small wheels. If the yet-to-be-named car is a success when it goes on sale next year, it would herald the emergence of Tata Motors on the global auto scene, mark the advent of India as a global center for small-car production and represent a victory for those who advocate making cheap goods for potential customers at the “bottom of the pyramid” in emerging markets. Most of all, it would give millions of people now relegated to lesser means of transportation the chance to drive cars.

It is a hugely ambitious project rivals have called it impossible for any company. But it is audacious for one that hadn’t even built cars a decade ago.

Sturdy as elephants, they are a fixture of the Indian landscape. Owners inevitably paint the exteriors in a cheerful riot of bright red, green, orange, blue and yellow and line the un-air-conditioned cabs with teakwood to keep them cooler in India’s searing heat.
