When is Tata going to introduce new Vista with CR4 engine?

The introduction of Tata Vista with CR4 engine seems to be a rumor only as Tata has no plans to rearrange engines of the Vista, instead it is planning for its new launches, which are the Tata Kite hatchback and compact sedan. The Vista comes with a 1405 cc TDI engine, making out 70 Bhp @ 4500 rpm and 135.4 Nm @ 2500 rpm. The car comes with a 5-speed manual transmission and returns a mileage of 19.4 kmpl. Tata's focus on the new cars has become more necessary as their Bolt hatchback and Zest sedan has not got the required response from the masses. They are focusing on more premium features, which would be added to the cars in order to make than more appealing to the customers.
