After Volkswagen, other diesel cars under ARAI scanner

In the wake of alleged emission norm violations by German car-maker Volkswagen, the Automotive Research Association of India (ARAI) is now also testing diesel-powered passenger cars sold by other companies in the country to ascertain the nitrogen oxide emissions from the vehicles.

In the wake of alleged emission norm violations by German car-maker Volkswagen, the Automotive Research Association of India (ARAI) is now also testing diesel-powered passenger cars sold by other companies in the country to ascertain the nitrogen oxide emissions from the vehicles.

“Initially, we were asked to investigate the diesel vehicles of Volkswagen by the ministry of heavy industry. Further, for relevant data collection purpose, we are also doing some additional measurements from passenger car models of other companies,” ARAI director Rashmi Urdhwareshe told FE.

ARAI had found “significant” difference between on-road emission levels and laboratory measurements, of the firm’s three diesel models in India — the Jetta, Audi A4 and Vento. The ARAI provides technical expertise in R&D, testing, certification, homologation and framing of vehicle regulations.

“At this moment, we will not be able to specify the companies and models as the tests are still going on. Our focus at the moment is diesel vehicles, because currently, the NOx emissions from diesel is what is under question. We are looking at vehicles having similar capacity engines and similar after treatment devices,” Urdhwareshe said. “We have lined up some tests and working on those. All the results will be submitted to the ministry of heavy industry,” she said. The other vehicles in the Indian market having diesel engines of similar capacity include the Maruti Suzuki Ciaz, Hyundai Verna, Honda City, Hyundai Elantra and Toyota Corolla, among others.

After the Volkswagen emission scandal broke in September, the government had asked ARAI to inspect the company's offerings in the Indian market for any violation of emission norms.

Earlier this month, the government issued a show-cause notice to Volkswagen after ARAI found the firm's diesel models to be emitting more than expected nitrogen oxide. Diesel vehicles of Volkswagen India tested by the agency were found to be emitting higher levels of Nitrogen Oxide compared with emission levels at the approval stage.
