Which of the following automaker is in news for emission cheating scandal?

Volkswagen
The German car giant Volkswagen is in news for emission cheating scandal. The automaker has admitted cheating emissions tests in the US. According to the Environmental Protection Agency (EPA), some cars being sold in America had devices in diesel engines that could detect when they were being tested, changing the performance accordingly to improve results. This resulted in a major discrepancy between the measured emissions and those produced during real-world driving—where the affected vehicles emitted up to 35 times the legal limit of nitrogen oxides (Nox). The offending programming was included in Volkswagen and Audi models between model years 2009 and 2015; it was included on 500,000 vehicles in the United States, and an estimated eleven million cars worldwide.
