Joe Doakes from Como Park emails:
Volkswagen takes over from Toyota as number one carmaker in the world, despite the scandal of being caught cheating on emissions tests.
“Despite” the scandal? Or because of it? Emissions tests are idiotic and anyone clever enough and bold enough to beat them probably has other good qualities.
From what I understand, it’s standard practice when dealing with the EPA that the actual total emissions are not lowered, they are simply diluted by forcing more clean air or water or whatever through the same discharge outlet. Too many parts per million of soot coming out the smoke stack? Don’t lower the total pollutants per pound of fuel used, or per erg of power generated, just increase the total air moving up the smoke stack by installing huge blowers to force more air into the final exhaust. Tried and approved methods, used widely throughout industry, approved by the EPA.
As I understand it, that’s essentially what VW did to pass the test. But they turned off those useless blowers anytime there was no monitor testing the output since by shutting off the blowers they saved the energy that doesn’t alter the total pollutants one iota, and that energy was diverted to actual work product that moves the car, hence better miles per gallon.
The EPA is pissed because VW beat the Kobayashi Maru.
It’s not, fooling Mother Bureaucracy.
