The Environmental Protection Agency and California regulators said on Friday that automaker Volkswagen admitted that its 3-liter V-6 diesel vehicles from the last seven years had violated clean-air standards.
The company officials said in a meeting on Thursday that emissions violations went much beyond the models from the last couple of years, and could stretch up to the last seven years.
This includes Volkswagen and Audi U.S. vehicles with 3-liter diesel engines from the 2009 to 2016 model years, the regulators said.
With the latest admissions, the scandal goes beyond small cars and includes heavier vehicles. This adds 75,000 vehicles to the list of vehicles that do not meet the environmental standards.
In September, this year, the automaker admitted it had installed software that allowed 482,000 diesel cars with 2.0L sold in the United States since 2009 to emit up to 40 times allowable emissions.
Emissions controls in such cars were activated only during laboratory testing. The company is currently facing investigations in the US and could face up to $18 billion fines.
