None knows for sure although, considering the current condition of IMC and our unstable economy, it is not coming anytime soon. Plus, IMC just launched its Yaris to replace Corolla models of Gli and Xli. Establishing a new plant for a particular model cost a lot of money. So, keeping their low-sale graphs of the previous year in mind, I would say it is not coming until 2021-2022.
Also, the new Grande’s price has just increased, it will be around 41 lakhs for on-road price now.
