Volkswagen Pollutes Its Reputatton with So-ftvvaretoCheatEmissicins
Testing
Volkswagen Group AG tried to aim highby embalTk~ ing on a strategy to bypass ‘Ibyota as the world’slarg.est auto maker. One part of that strategy called for tripling u.s. sales in a decade by promoting “clean” diesel-powered cars promising low erniSSlol’!-s Ilr).d high mileage without sacrificing performance. It turned Qut that about 580,000 cars. in. the United States and almost 10.5 million. more clean diesel models sold worldwide by VW under its vw, Audi, and Porsche brands weren’t really “green” at all.
On September 18,2015, the U.S. Environmental Protection Agency (EPA) issued a notice ofviolation of the Clean Air Act to the Volkswagen Group after finding that vol1$.swagen had intentiona11y programmed turbocharged directinjection diesel engines to activate certain emissions controls only during 1aboratolTY emissions testing. The programming caused the vehicle’s nitrogen oxide (NOx) output to meet U.s, standards during regulatolTY testing bu.t emit up to 40 times more NOx When the Gars were actually driven on the road. Volkswagen put this software in about 11 mi1lioncars worldwide, and in 500,000 in the United States, during model years 2009 through 2015.
Volkswagen was able to get away with cheating on emissions tests for years because it wa~ hidden in lines ofsoftware code. Only after investigations by environmental groups and independent researchers did Volkswagen’s deception come to light. Many functions in today’s automobiles are controlled by millions ofUnes ofsoftware program code, inc1uq.ing monitoring carbon monoxide and nitrogen oxide levels to help a car control the amountofpollutants it emits. Diesel engines don’t emit much carbon monoxide, but they generally emit a greater amount of nitrogen oxide (NOx), a cOmponent in lowatmosphere ozone and acid rain. The United States has tougher NOx standards than Europe, where diesel cars are more common.
Diesel-powered cars use sensors and enginemanagement software to monitor and limit emission levels. The software can control how much NOx is produced during combustion by regulating the car’s mix of diesel fuel and oxy{Sen or by deploying NOx traps to capture the pollutant and catalysts to clean emissions. However, these pollution-reducing measures also reduce fuel economy.

1970s..Ford was fined $7.8 mi11ion in 1998 for using defei3-t devices enabling Econoline vansto reduce emissions to pass testing and then to exceed pollution limits when driving at highway speeds. General Motors paid $11 million in fines in 1995 for the defeat devices that secretly overrode the emissions control system at times on some ofits Cadill,,+<;: cars. Caterpillar; Volvo, Renault, and other manufacturers were fined $83.4 million in 1998 forusing defeat devices. Auto manufacturers have also used other ploys to demonstrate better performance and gas mileage, such as taping cars doors and grilles to improve aerodynamics or making test vehicles lighter by removing the back seats.
The erpiss.ions scandal has shaken not just yolkswagen but the entire auto industry. Volkswagen pecame the target ofregulatory iiwestigations in m1Jltiple countries, and Volkswagen’s stock price fell in value by a third in the days immediately following the cheating revelation. Chiefexecutive Winterkorn resigned, and the head ofbrand development HeinzJakob Neusser, Audi research .md development head Ulrich Hackenberg, and Porsche research and development headWolfgang were suspended. Volkswagen announced plans to spend $’7.3 billion, later
