Submission declined on 25 May 2025 by Timtrent (talk). This submission reads more like an essay than an encyclopedia article. Submissions should summarise information in secondary, reliable sources and not contain opinions or original research. Please write about the topic from a neutral point of view in an encyclopedic manner. The proposed article does not have sufficient content to require an article of its own, but it could be merged into the existing article at Volkswagen emissions scandal. Since anyone can edit Wikipedia, you are welcome to add that information yourself. Thank you.

Claim of Early Prediction of Emission Scam
In the 1990s, diesel vehicle emission standards were progressively tightened in Europe (with the introduction of Euro 1 in 1992, followed by subsequent Euro standards and in the United States by EPA &CARB standards.[1] . The simultaneous pursuit of emission control and engine performance presented a significant challenge for diesel car manufacturers using the then-available technology of Exhaust Gas Recirculation (EGR). With this technology, portion of the Exhaust gas is circulated back to the inlet manifold. The recirculated exhaust replaces part of fresh air and its oxygen content, reducing total availability of Oxygen for combustion in the engine. Also, the non-combustible gases and water vapour in the exhaust absorb engine heat. Both these effects reduce the formation of NOx. More quantity of EGR is required to meet stricter Emission standard of more NOx reduction. However EGR has an effect of reduction of engine performance of power and fuel consumption. It was common knowledge known to everyone in the field that increasing EGR led to lowering of engine performance.[2]
In early1990s, Arunachalam Sivakumar, an alumnus of IIT Madras with experience in the auto ancillary industry, particularly in product development and testing,[3] observed this situation. He feared that the manufacturers might make the product to behave in one way to meet tough emission standards in the test and behave differently in the field to achieve desired engine performance at the cost of more emission.. He formulated a novel observation akin to Murphy's Law: "Design a tough 'product testing specification' and you end up with products which work well only in the test rigs and not in the field," referring to the potential for a product to behave differently during testing and in real-world use.
Sivakumar did not publicize this prediction as there was no awareness of impending scam then. The internet service was in nascent stage. He shared it with his colleagues by displaying it in his office. Sivakumar after his retirement as Associate Director Technology of Murugappa Group in 2005,documented this observation in his book, "In Search of Technology - Experiences of an IITian," published in 2006 by S Viswanathan based in Chennai)[4] The content of the book was appreciated by industrialists and technologists including APJ Abdul Kalam, the then President of India.[5] Review of the book by established National newspaper “The Hindu” without mentioning the observation on product testing specifically, appreciated the observations in the book as reflection of gap between idealism and reality.[6] . Sujatha, famous Tamil writer and leader of the team which developed India’s electronic voting machine, commented that the observations conveyed Sivakumar’s experience and findings in concise manner.[7] [8]
In 2015, the Volkswagen emissions scandal became a widely reported instance of a major automaker introducing a defeat device that resulted in significant discrepancies between test results and real-world emissions.Sivakumar interpreted the Volkswagen scandal as a realization of his earlier concerns of making the product to meet pollution control standards in the test and fare badly in the field. IIT Madras conducting “Leadership Lecture Series” in which its Alumni shared their career leanings with current students, invited Sivakumar in 2016. Sivakumar utilized this opportunity to mention briefly about emission scam and claimed that his prediction documented in his book published in 2006 came true by the action of Volkswagen introducing defeat device making their vehicles to perform well on emission front during test and poorly in the field but with desired engine performance[9]. Apart from damaging the reputation of Volkswagen, the emission scam as per Reuter report, caused significant financial consequences for the company, estimated at €31.3 billion in fees, penalties, buyback costs, and financial settlements.[10]
