Porsche, more Audi models pulled into Volkswagen emissions scandal !

WASHINGTON:
Volkswagen used devices to cheat air pollution tests in diesel luxury vehicles, US environmental regulators said on Monday, in a new blow to the automaker already reeling from similar allegations regarding millions of smaller diesel engines.

The US Environmental Protection Agency said it is now looking at 3.0-litre V6 diesel engines used mostly in larger, more expensive models like the Porsche Cayenne sport utility vehicle in addition to engines on Jettas, Passats and other mass-market models whose test-deceiving software were initially targeted by the agency in mid-September.

Volkswagen in a response Monday took issue with the EPA’s findings, saying that “no software has been installed” in its 3.0-litre V6 diesel engines “to alter emissions characteristics in a forbidden manner.”

VW made similar denials for more than a year to US regulators before admitting to cheating on the four-cylinder diesels.

A VW group source familiar with the EPA investigation on Monday said, “We want to know more from the regulators about how they came to this conclusion. We’re not sure how they came up with their findings, and would like a better opportunity to review the data with the regulators.”
