Tata Motors’ overdue launch of its tiny ultracheap car for the masses faces limited supply, factory delays, and a growing field of rivals. But six years after the project was conceived, Ratan Tata, chairman of the Tata Group, announced on Mar. 23 that the world’s cheapest car would soon be available in one of the world’s fastest-growing car markets. Tata Motors, which is 37% owned by Tata Group, plans to start a lottery to pick 100,000 people who will be eligible to buy the first Nano cars that roll off the production line. “We have made a promise and we have kept that promise,” Tata told journalists in Mumbai.
