The Tata Nano, the world’s cheapest car, is being launched in India. It cost 100,000 rupees ($1,979; ?1,366). The Nano is being launched later in Mumbai, before going on sale across India over the next 10 days. Tata hopes the 10 feet (3 metre) long, five-seater car will be cheap enough to encourage millions of Indians to trade up from their motorcycles. Car industry analysts estimate it will take five or six years for Tata to start to make a profit from the Nano.The four-door Nano has a 33bhp, 624cc engine at the rear. The basic model has no airbags, air conditioning, radio, or power steering. However, more luxurious versions will be available. A slightly bigger European version, the Nano Europa is due to follow in 2011, and is expected to cost nearer to ?4,000.
