According to data obtained by the Guardian, Mercedes-Benz, Honda, Mazda and Mitsubishi are now on the growing list of automakers whose diesel cars pollute the air far beyond the current regulatory limits set in Europe and the UK. Last week the Guardian had discovered diesel cars from Nissan, Hyundai, Fiat, Renault, Volvo and Jeep are spewing significantly higher levels of nitrous oxide (Nox) than what is measured in emissions tests.
Source of the new data is from the on-the-road testing program performed by Emissions Analytics. The data is collected under carefully controlled conditions and closely matches the real-world test the European commission wants to introduce.
The Environmental Protection Agency (EPA) accused Volkswagen of cheating on its emission tests for diesel powered cars. The second largest automaker in the world has admitted to installing a software cheating program on VW and Audi diesel vehicles manufactured between 2009 and 2015.
Michael Horn, president and CEO of Volkswagen of American, testified before members of the House Energy and Commerce investigations subcommittee apologizing for the unknown actions taken by VW engineers and stressed that his company is working on a solution that will probably involve both software and hardware, which could cost the up to $7.3 billion.
