Volkswagen pleaded guilty to three felony charges for its emissions cheating scandal and will pay a $4.3 billion civil penalty, the largest for any automaker, as six of the company’s executives were indicted, the Justice Department announced Wednesday.

Justice announced criminal indictments of six company executives on charges including conspiracy to defraud the American people as well as charges of wire fraud and transporting vehicles across borders with the intent to violate U.S. law. The company installed defeat device software in 600,000 “clean diesel” vehicles that allowed the vehicles to pass emissions tests but then switched to a normal mode after testing that allowed the cars to spew about 40 times the legal limit of nitrogen into the atmosphere, violating the Clean Air Act.
