That is why wrote 4-5 posts back that there cannot be any segmentation of cars possible as there is no valid reasoning to substantiate it. Who are we to call a car as truly premium? The definition of premium is very subjective. For you it may be X for the other person it may be Y. As there is no standardized definition of premium hatchback, everyone comes up with their own definition. The only car which has got majority of the votes to be called a truly premium hatchback car in india is Honda Jazz. Its the only car which has got most of the premium features - interiors, exteriors, engine, power, features, safety, Honda badge, drivability etc etc. All other cars fail in one parameter or the other. I20 is a great hatchback, but is a little underpowered. Polo ticks most of the boxes but is a 3 pot engine. So some people might raise an eyebrow to call it truly premium.
The truth is Indian car market is evolving. A truly premium hatchback will find few takers in today's economic climate in India. Thats why, there is no reason which can be attributed to the low sales of Jazz inspite of it having all the desired features in a premium hatch - great power, ample space, truly premium interior quality, great features, superb safety, excellent drivability, superior iv-tech engine. So what's stopping its sales? No price for guessing - highly priced. That's why when Honda launched its 2nd hatchback, Brio, at a lower price range and subjective looks, it found so many takers.
