The new vehicle standard is going to be light and electric because they are going to be range sensitive from now on. Everyone will be conscious that their personal weight and passenger weight is a major fraction of total load. This was rarely the case before.
I see real merit in a short two seater vehicle not dissimilar to this. Getting rid of the unloved and barely used rear seat is a great weight saver. Right now, such a design would lengthen the effective range from current battery technology.
Manufacturing technology has clearly evolved and this is a massive shift into a brand new automotive market that is many time larger than the present market in terms of vehicle volume.
World's cheapest car is launched
The Tata Nano, the world's cheapest car, has been launched in India.
Costing just 100,000 rupees ($1,979; £1,366), the Nano will now go on sale across India next month, with deliveries starting in July.
Tata hopes the 10-foot (3-metre) long, five-seater car will be cheap enough to encourage millions of Indians to trade up from their motorcycles.
Tata owner Ratan Tata has described the Nano as a "milestone". Analysts say it will not make a profit for six years.
Tata's managing director Ravi Kant said that from the first orders, a ballot would then select the initial 100,000 people to get their Nano.
"I think we are at the gates of offering a new form of transport to the people of India and later, I hope, other markets elsewhere in the world," Mr Tata added.
Environmentalists are warning that the Nano will add to India's already clogged up roads, and pollution levels will soar. Tata says the Nano will be the least polluting car in India.
The basic model has no airbags, air conditioning, radio, or power steering.
