The BS6 norms, for all vehicles, are set to come into force in India from April 1, 2020, and several manufacturers are already working on getting their vehicles at least BS6 ready by this year. Now, the upgradation from BSIV to BSVI is, in fact, complex engineering, and Tata says that this challenge demands pushing the technological advancements to the limits, and a turnaround of the infrastructure and facilities required for this development. This is why, the company now has a state of the art "Emission Test Facility" installed at the Power Systems Engineering Division (PSE), in ERC, Pune. This facility serves as one of the crucial milestones for BS6 implementation.

Speaking on the occasion Rajendra Petkar, Chief Technology Officer (CTO), Tata Motors said, "This BS6 engine certification milestone has been achieved with intense design and development focus, by leveraging in-house capabilities and those of our technology partners. We have worked hard to build a leadership position in the market by providing our customers with economical, best-in-class natural gas vehicle products in the commercial vehicle market and this development of BS6 solution will further reinforce our market offering."
