On September 18, 2015 (August 6, 2015 lunar calendar), Volkswagen's exhaust emissions cheating incident in Germany. Volkswagen Emissions Gate, September 18, 2015, the US Environmental Protection Agency accused some diesel vehicles sold by Volkswagen of installing software specifically for exhaust emissions testing, which can identify whether the car is in the state of being tested, and then secretly start during vehicle inspection, so that the car can pass the inspection with "high environmental standards". When driving, these cars emit a lot of pollutants, up to 40 times the legal standard in the United States. The vehicles involved in the illegal emissions include Jetta, Beetle, Golf, Audi A3 sold after 2008, and Passat from 2014 to 2015. According to the US "Clean Air Act", each car that violates the emission regulations may be fined up to 37,500 US dollars, and the total amount can be as high as 18 billion US dollars. The Volkswagen Group's "Diesel Door" incident has caused a lot of uproar, and many diesel models of the group's sub-brands are involved, which has caused great damage to the good reputation that Volkswagen has long maintained. Recently, Netcom learned from the US media Autonews that a total of 482,000 diesel vehicles in the US market have been affected by the "cheating" incident. The California Air Resources Board has ordered Volkswagen Group to submit corresponding solutions before November 20. The Volkswagen Group has previously admitted to using engine emission control software to enable Volkswagen diesel vehicles to pass official exhaust tests to a high standard, but emit a lot of pollutants in daily use. The number of Volkswagen diesel vehicles involved is about 11 million, involving Volkswagen, Audi, Skoda and Seat. There are 482,000 problem vehicles in the US market. Volkswagen's US CEO Michael Horn previously blamed the "cheating" incident at the hearing on "the personal behavior of individual engineers" and said that "it will take at least a year to complete the repair of 482,000 vehicles", but the relevant US government departments do not seem to give Volkswagen much time. The California Air Resources Board had previously sent a letter to Volkswagen on September 18, giving Volkswagen Group 45 working days (that is, before November 20) to propose a solution. The "cheating" incident is the most serious crisis Volkswagen has experienced in 78 years. Affected by the incident, Martin Winterkorn, Volkswagen's long-serving group president, was forced to step down, the group's market value plummeted by one-third, the global auto industry and the German economy suffered setbacks, and countries around the world also began to investigate whether their countries were also affected. Volkswagen's emissions fraud is actually just a microcosm of the unhealthy development of the auto industry. I hope all car companies can take this as a warning and truly reassure consumers.
