According to Tata, the possibility of introducing Jaguar and Land Rover into India will not be ruled out in five years, but considering the value of these two brands, I think it is very unlikely to produce them in India.
The technology of these two brands is still in Ford's hands. Even with these technologies, Tata can only apply these luxury car technologies to Jaguar and Land Rover.
This is like the result of Fiat's acquisition of Ferrari. So far, Fiat has never produced a sports car.
In the last century, Rover moved from BMW to Ford.
After entering China, the failure of strategy made the cooperation between Ford and SAIC unsuccessful, but instead made it "SAIC-GM". Ford's road to cooperation in China is not as smooth as GM's. The cold reception in China made Ford only sell Rover's technology (developed by BMW) to SAIC instead of Rover's brand, which is largely unwilling to re-emerge in SAIC's hands. Of course, Ford is unwilling to buy Rover into any China enterprise. SAIC had to create its own "Roewe".
Tata acquired Jaguar and Land Rover from Ford, and also acquired the trademark rights of Rover. Now Tata's "resurrected" Rover is the biggest threat to SAIC Roewe. It is also the result that Ford hopes to see.
Now there seems to be a rumor that SAIC is talking about buying Volvo and Hummer. I believe SAIC is fully capable of fighting Tata.
