acdii Report post Posted June 17, 2014 Prove me wrong otherwise. I never stated fact, however you believe that I am. How is it Toyota cars hit EPA when driven properly and no others do? Gee could it be because Toyota actually does test them? And yes it did go WAY over your HEAD(using your own obnoxious typing here). Theories are what EPA testing is all about. You run mathematical formulas and put a car on a dyno to simulate those formulas, and the end result are your EPA numbers. How do you prove them out? Real world testing. If a theory is flawed, the outcome is skewed results such as what Ford found. So maybe Toyota has better mathematicians, or maybe they just test longer and more frequent to ensure that what they sell to a customer is what the customer is expecting. It does not matter what EPA says, if a theory is flawed, a theory is flawed. If a car company follows those theories and the outcome is wrong because of a mathematical error it does not matter what EPA says, the outcome is wrong. You MUST prove out any theory, no matter what. After all the reports of low MPG Ford looked long and hard at their test results and found the error. Where did those tests come from? EPA. So what I am saying is Trust but verify, Ford could have done some extensive testing prior to releasing the EPA numbers, and had they done so, might have found the flaw and corrected it in time to prevent any bad press. That is there choice in all this, so prove me wrong. Any car manufacturer can test after submitting their EPA tests to verify them that is their choice, and if they find the real world numbers don't match up, it is up to them to figure out why and resubmit. That is their choice. Going back to what I originally stated, any car company has a choice prior to releasing their official EPA numbers. They run their Dyno tests based on their calculations, and submit that, or they run the dyno tests and run real world tests to validate the results. If the two match, they are golden, if they dont, then they go back and find out why. End result is they still meet all the EPA regulations, but they also know that they are valid. 2 hybridbear and corncobs reacted to this Quote Share this post Link to post Share on other sites
