US sues VW over emissions-cheating diesel cars

WASHINGTON (AP) — The Justice Department sued Volkswagen on Monday over emissions-cheating software found in nearly 600,000 vehicles sold in the United States, potentially exposing the company to billions of dollars in penalties for clean air violations.
The civil complaint against the German automaker, filed on behalf of the Environmental Protection Agency in U.S. District Court in Detroit, alleges the company illegally installed software designed to make its "clean diesel" engines pass federal emissions standards while undergoing laboratory testing. The vehicles then switched off those measures in real-world driving conditions, spewing harmful gases at up to 40 times what is allowed under federal environmental standards.
