Point here is if Tata could develop his own BS6 engine, then cost will come down down and Harrier can become more competitive,
We all know Tata couldn't integrate this engine like Fiat did in Compass. There are multiple issues. When you design your own engine you can integrate it better. One of Hexa owner, who took test drive of Harrier found Hexa/Safari engine more silent and vibration free.
Anyway Tata has to develop BS6 engine for Nexon, Safari/Hexa then why not for Harrier?
