There have been persistent rumours about Tata working on yet another car in the small car space.  The project is codenamed Dolphin and this car is supposed to slot in between the Indica and the Nano.  Indian Cars is now reporting that this car will incorporate the tall boy architecture as seen in the Wagon R and that this car which will be high on vertical space will target the Wagon R directly.  The Wagon R is the second largest selling car model of Maruti after the Alto and sell an average of 12,000 units every month. It seems every manufacturer wants to break the Maruti stronghold.
