Nobody charged the EPA with ensuring adherence to some made up test cycle, but to the emission limits. If the test cycle is your approximation of real world behavior, it is highly negligent to never confirm that real world results actually match the approximation! This is science 101.
- ip26 8y agoI'm not a test engineer but work closely with them- two of their core ongoing job functions are monitoring real world performance to find test escapes, and adapting the tests to more closely drive real world performance.
- TheRealDunkirk 8y agoI’m specifically arguing that the FTP cycle result IS, in fact, a real world result. So to me, claiming that the EPA needed to do their own verification would be silly. The only reason to do this would be to catch cheaters. I know I’m naive, and very trusting. I would never have thought a company to have the utter stones to completely fake the results as VW did. If you’ve looked at the depths of their algorithms to do it, you see the effort that went into it. I just would never expect such behavior from one of the largest auto makers. It’s so far beyond the pale to my expectations that I can’t blame the EPA for not catching it. YMMV.
