This is commonly believed and seems to massively let VW off the hook. Almost everyone was overfitting their optimization to the test and thus not delivering real world lower emissions. That's not illegal, just unethical, particularly since they also lobbied to not make the test more realistic. But VW actually detected it was in the test loop and changed the settings. That's a defeat device and completely illegal. There were a few much smaller cases of similar things found in other manufacturers but nothing even close to the scale VW did it.
- nickff 2y agoA bunch of the other automakers had similar 'defeat devices', and they're called out on the Wikipedia page.
- justinclift 2y agoWow. Even Mercedes-Benz were at it: Earlier, Feb 2018, German newspaper Bild am Sonntag reported that US authorities investigating Mercedes have discovered that its vehicles are equipped with illegal software to help them pass United States' stringent emission tests. The claimed defeat devices include a Bit 15 mode to switch off emissions control after 16 miles of driving (the length of an official U.S. emissions test), and Slipguard which tries to directly determine if the car is being tested based on speed and acceleration profiles.
- pedrocr 2y agoI mentioned that. There were others but nothing at the scale of what VW did.
