NEW YORK: Volkswagen AG and its Porsche AG unit have agreed to a class-action settlement worth at least $80 million to resolve claims it skewed emissions and fuel economy data on 500,000 Porsche vehicles in the United States, court documents show.

The settlement, filed in US District Court in San Francisco, must be approved by a federal judge. It covers 2005 through 2020 model year Porsche vehicles after owners accused the automaker of physically altering test vehicles that affected emissions and fuel economy results.

Owners of eligible vehicles will receive payments of $250 to $1,109 per vehicle. Porsche confirmed the settlement in a statement but said it has “not acknowledged the allegations in these proceedings. The agreement serves to end the issue. The comparison applies only to vehicles sold in the United States.”

Scrutiny of Volkswagen’s vehicles grew after the German automaker in 2015 disclosed it had used sophisticated software to evade emissions requirements in nearly 11 million diesel vehicles worldwide.

VW settled US criminal and civil actions prompted by the cheating scandal for more than $20 billion. The automaker pleaded guilty in 2017 to fraud, obstruction of justice and falsifying statements.

Lawyers for the Porsche owners said the automaker physically altered the hardware - gears connecting the drive shaft and rear axle - and manipulated the software of testing vehicles. The test vehicles emitted fewer pollutants and were more fuel efficient than the production vehicles consumers bought or leased.
