Volkswagen emissions scandal - Wikipedia 1 of 41 Volkswagen emissions scandal The Volkswagen emissions scandal, also known as Dieselgate[23] or Volkswagen emissions Emissionsgate,[24] began in September 2015, when the United States Environmental Protection Agency (EPA) issued a notice of violation of the Clean Air Act to German scandal automaker Volkswagen Group. The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing which caused the vehicles' NOx output to meet US standards during regulatory testing, but emit up to 40 times more NOx in real- world driving.[25] Volkswagen deployed this software in about 11 million cars worldwide, including 500,000 in the United States, in model years 2009 through 2015.[26][27][28][29] In 2014, the California Air Resources Board (CARB) had commissioned a study on A 2010 Volkswagen Golf TDI with emissions discrepancies between European and US models of vehicles from the defeat device displaying "Clean International Council on Clean Transportation (ICCT), summing up the data from three Diesel" at the Detroit Auto Show different sources on 15 vehicles. Among them was a group of five scientists at West Date 2008-2015 Virginia University, who detected additional emissions during live road tests on two out of three diesel cars. ICCT also purchased data from two other sources. The new road testing Location Worldwide data and the purchased data were generated using Portable Emissions Measurement Also known Dieselgate, Systems (PEMS) developed by multiple individuals in the mid-late 1990s and published in as Emissionsgate May 2014.[30][31][32] Type Emission standard Regulators in multiple countries began to investigate Volkswagen,[33] and its stock price violations fell in value by a third in the days immediately after the news. Volkswagen Group CEO Cause Engaging full Martin Winterkorn resigned, and the head of brand development Heinz-Jakob Neusser, emissions control only Audi research and development head Ulrich Hackenberg, and Porsche research and during testing development head Wolfgang Hatz were suspended. Volkswagen announced plans in April 2016 to spend €16.2 billion (US$18.32 billion at April 2016 exchange rates)[34] on Participants International Council rectifying the emissions issues, and planned to refit the affected vehicles as part of a recall on Clean campaign. In January 2017, Volkswagen pleaded guilty to criminal charges and signed an Transportation, West agreed Statement of Facts, which drew on the results of an investigation Volkswagen had Virginia University, itself commissioned from US lawyers Jones Day. The statement set out how engineers had Volkswagen Group, US developed the defeat devices, because diesel models could not pass US emissions tests EPA, other regulators without them, and deliberately sought to conceal their use.[35] In April 2017, a US federal judge ordered Volkswagen to pay a $2.8 billion criminal fine for "rigging diesel-powered Outcome Fines and lawsuits vehicles to cheat on government emissions tests". The "unprecedented" plea deal Footage vwdieselinfo.com (http [36] formalized the punishment which Volkswagen had agreed to. Winterkorn was charged s://vwdieselinfo.com) in the United States with fraud and conspiracy on 3 May 2018.[15] As of 1 June 2020, the scandal had cost VW $33.3 billion in fines, penalties, financial settlements and buyback Timeline costs.[37] Various government and civil actions are currently undergoing in the U.S., as well as the European Union, where most of the affected vehicles are located; while they remain 1999 New US Tier 2 rules legal to drive there, consumers groups and governments seek to make sure Volkswagen has established to replace compensated these owners appropriately as they had to do in the United States. Tier 1. NOx limit decreasing from 1.0 The scandal raised awareness over the higher levels of pollution emitted by all diesel- g/mi to 0.07 g/mi powered vehicles from a wide range of car makers, which under real-world driving conditions exceeded legal emission limits. A study conducted by ICCT and ADAC showed 2004–2009 Phase in period of the biggest deviations from Volvo, Renault, Jeep, Hyundai, Citroën and Fiat,[38][39][40] diesel emissions rules resulting in investigations opening into other diesel emissions scandals. A discussion was 2007 Volkswagen suspends sparked on the topic of software-controlled machinery being generally prone to cheating, sales of current diesel and a way out would be to open source the software for public scrutiny.[41][42][43] lines awaiting technology to meet new standards.

The “lean NOx trap” team won, but their solution did not actually work.
