During the ongoing probe into the VW dieselgate‘s impact in India, ARAI (Automotive Research Association of India) found that select India-spec VW Group models recorded 5-6 times more emissions in on-road tests as against the lab tests.
The Indian automotive authority has issued a show cause notice to the automaker to provide a technical explanation of the discrepancy in the next 2-3 weeks. ARAI conducted on-road tests on 10-11 cars of different VW Group models like Polo, Jetta, Vento and Audi A4. The automaker previously confirmed that 3,14,000 cars sold in India are powered by the controversial EA189 diesel engine family.
The significant variant in the emission between laboratory and on-road tests demonstrated that there exists an opportunity for the automakers to circumvent the emission tests. So, the concerned authorities may also widen their inspection by subjecting cars from other automakers as well to the on-road tests.
This finding has prompted the Indian government to think about including on-road emissions test in the approval procedure for all cars in the future to ensure stricter scrutiny. Thanks to VW dieselgate, emission tests in India may never be the same.
