US says Volkswagen also violated emission rules in larger engines
[WASHINGTON] The Volkswagen emissions-cheating scandal widened Monday when US regulators said the German automaker also included illegal "defeat devices" on its larger 3.0 litre diesel engines during the past three years.
Volkswagen had already admitted including the software, which cheats pollution tests, in its smaller 2.0 litre diesels equipped in some 11 million 2009-2015 model year cars worldwide.
But the Environmental Protection Agency said it had discovered in its investigation that various six-cylinder 3.0 litre diesel VW Touareg, Porsche Cayenne and Audis from the 2014-2016 model years and distributed in the United States had also been rigged with the software.
"We have clear evidence of these additional violations," said Cynthia Giles, an official with the EPA's Enforcement and Compliance Assurance office.
"VW has once again failed its obligation to comply with the law that protects clean air for all Americans," she said.
VW DENIES NEW ALLEGATIONS
In a statement from its headquarters in Wolfsburg, Germany, the company denied its 3.0 litre engines had defeat devices.
"Volkswagen AG wishes to emphasize that no software has been installed in the 3-litre V6 diesel power units to alter emissions characteristics in a forbidden manner," it said.
"Volkswagen will cooperate fully with the EPA (to) clarify this matter in its entirety." The expansion of the scandal spelled further damage to Volkswagen, the world's second-largest automaker and long an emblem of Germany's industrial might.
Already one chief executive of the company, Martin Winterkorn, has lost his job, and shares of the giant have lost nearly one-third of their value since the scandal erupted.
The new US notice of violation, for the larger-engined cars, could weigh on Winterkorn's replacement, Matthias Mueller, who was elevated from running VW's Porsche subsidiary. At the time of his promotion, Porsche vehicles were not known to have the defeat devices.
Moreover, the first notice of violation on September 18, which launched the scandal, made clear that from the EPA alone, the company was facing a potential US$18 billion in fines, based on the maximum allowed per vehicle and the half-million US-sold cars covered.
There are also a number of owner lawsuits against the company, and it could be hit with fines in other countries and regions as well.
The new notice covers about 10,000 mostly luxury cars already sold in the United States, and an unknown number still unsold.
But, as with the initial notice, it was possible that the same cars sold elsewhere would be shown to have software defeat devices as well.
The software makes the engines run according to US standards when emissions testing is ongoing.
"At exactly one second" after the emission test ends, Ms Giles said, the software switches into standard-drive mode in which poisonous nitrogen oxide emissions rise to up to nine times the EPA standard.
"The vehicles operate at this higher emitting 'normal' mode when the vehicle detects that it is not undergoing an emissions test," she said.
"This design feature is an illegal defeat device," she said.
That put Volkswagen in violation of two provisions of the US Clean Air Act, in making and selling cars that have defeat devices and that do not meet US emissions standards.
The new information came out of ongoing joint investigations into actual emissions performance by a range of cars, including those from other makers besides Volkswagen, by the EPA, the California Air Resources Board and Environment Canada.
Ms Giles said they had not discovered the problem on any other makers' vehicles so far.
After the initial accusations in September, Volkswagen publicly admitted that its smaller diesels had the defeat devices, and promised full cooperation in probes by not only US but also German and European authorities, and those in other countries.
The US House of Representatives Energy and Commerce Committee, which has opened a probe into the emissions scandal, said the new allegations meant "it's time for Volkswagen to fully come clean." "The EPA expanding its investigation prompts questions regarding the prevalence of the emissions cheating and how it went undetected for so long," committee leaders said in a joint statement.
The scandal is clearly taking a toll on Volkswagen. Last week the company booked its first quarterly loss in more than 15 years as it set aside 6.7 billion euros (S$10.3 billion) to cover the initial costs of the scandal.
Chief financial officer Frank Witter warned of further "considerable financial charges" from the emissions case.
It was "far too early to calculate the cost of any legal measures," Mr Witter said. "The financial burden will be enormous, but manageable."
