The marketing was exuberant. The engineering reality was more complicated. AVL of Austria had optimised the design. Bosch of Germany supplied the engine control unit and calibration. Honeywell of the United States designed the turbocharger. Testing was conducted in the UK and South Korea. Tata owned the architecture and the intellectual property. But the word “indigenous,” in this context, was doing a lot of heavy lifting.
The Revotron story is not an indictment of Tata. It is a parable for India’s entire passenger car industry. After more than seven decades of automobile manufacturing, the world’s third-largest car market has never fully designed and built a passenger car engine without significant foreign engineering involvement. Almost every engine in every Indian car — past and present — traces its intellectual lineage to Europe, Japan, or the United States. This is not a matter of manufacturing capability. India builds engines at enormous scale and impressive quality…….”
