The Nano hasn't been the unmitigated success that Tata wanted it to be in the Indian market, so naturally the company is looking at overseas markets to sell the car. What is surprising is the markets it is planning to expand to; markets like Europe and the USA.
Small cars have not been very successful in the American market - what is considered a large hatchback by Indian standards is the smallest of cars in the US market - and the Nano is a few sizes smaller than that. Tata plans to spruce up the Nano with features that will allow it to be sold in those markets, like ABS and airbags. It will definitely get a bigger, more powerful engine, disc brakes and power steering. We won't be surprised to see features like climate control and traction control being included on the car.
The Nano Megapixel concept could be the starting point for this bigger Nano - of course, the concept had a hybrid drivetrain, but Tata has set a target of USD 10,000 for the US-market car, so we don't expect electric motors to make the final cut. The launch date is scheduled for 2015. Logistics might be a problem for the US market, too, as there is no Tata dealer network in the USA and it is unclear if the Nano can be sold alongside Jaguars and Land Rovers.
