Photos: Tata's budget Nano car

Ratan Tata, chairman of parent company Tata Group, stands with the Nano after driving it on stage at the New Delhi Auto Expo on Thursday. He explained the motivation behind the car this way:

"I observed families riding on two-wheelers -- the father driving the scooter, his young kid standing in front of him, his wife seated behind him holding a little baby," he said at the unveiling ceremony, according to Tata's press release. "It lead me to wonder whether one could conceive of a safe, affordable, all-weather form of transport for such a family."
