Ratan Tata's initial doodle was to rebuild a car around a "scooter so that those using it could travel safer", says Noronha and colleagues in the book.
Christabelle Noronha, who co-authored the book with Philip Chacko and Sujata Agarwal, says: "The Nano has been and remains essentially a product of Ratan Tata's imagination and his desire to recast the car as a means of affordable personal obility for middle class India". "We had a strong feeling that the Nano story needed to be chronicled - that the story would be something that ordinary readers would be keen to know and understand," Noronha told IANS.
The writers met more than 100 people from Tata Motors, including "engineers, dealers as well as Nano owners, before getting down to writing the book".
"It took us a year to write the book. We began in April 2009," Noronha said. The writer said "one of the greatest plus points of Nano was to marry quality with affordability".
