Sales of Tata Motors' Nano, the world's cheapest car, are below expectations. But the Indian carmaker isn't giving up. Last week Tata unveiled upgrades, with no price increase, that include better fuel efficiency, a more powerful engine -- up 3 hp, to a slammin' 37.5 -- and new interiors.
Tata has sold around 130,000 Nanos since the car was launched in a blaze of publicity in April 2009. The four-seater car can sell for as little as $2,730.
Rising costs forced Tata to increase the car's price, and a land dispute at the model's original factory forced the company to move production to another site.
In November, Tata offered Nano owners the option to install additional safety protection in their vehicles after local media reported that seven cars had caught fire.
