If it will perfrom, it will survive

I am following the Nano News articles since last year and i have read enough about this car. Price is low no doubt about it. One major issue which people are talking most about is that it is very critical for Nano to perform well in Indian market because it is the only way it can survive in India and in the world.Passenger's safety is the other issue which is concerning many Auto analysts. Although from the company's side they are giving assurance about following all safety majors which are necessary in a car to ensure safety of customers is there. Second thing is its engine which is as powerful as 623cc. Is this much of power enough for a car to survive in long or usual journeys of about 400 to 500 km.
