Volkswagen Allegedly Cheated On US Emission Tests According To EPA Probe
WASHINGTON — The Obama administration on Friday directed Volkswagen to recall nearly a half-million cars, saying the automaker illegally installed software in its diesel-power cars to evade standards for reducing smog.
The Environmental Protection Agency accused the German automaker of using software to detect when the car is undergoing its periodic state emissions testing. Only during such tests are the cars’ full emissions control systems turned on. During normal driving situations, the controls are turned off, allowing the cars to spew as much as 40 times as much pollution as allowed under the Clean Air Act, the E.P.A. said.
“We expected better from Volkswagen,” said Cynthia Giles, the E.P.A.’s assistant administrator for the Office of Enforcement and Compliance. She called the automaker’s actions “a threat to public health.”
Agency officials issued the car company a notice of violation and said it had admitted to the use of a so-called defeat device. The recall involves 4-cylinder Volkswagen and Audi vehicles from model years 2009-15.
A spokeswoman for Volkswagen confirmed that the company had received the notice and said the automaker was cooperating with the investigation. She declined to comment further on the case.
The software was designed to conceal the cars’ emission of the pollutant nitrogen oxide, which contributes to the creation of ozone and smog. The pollutants are linked to a range of health problems, including asthma attacks, other respiratory diseases and premature death.
Experts in automotive technology said that disengaging the pollution controls on a diesel-fueled car can yield better performance, including increased torque and acceleration.
