As I stated, I do know how they work (funny how I have to keep telling you that). So, this car has to be driven differently from other hybrids to attain the rating???? Explain that to the American public. Just amazing to me that all the other cars I mentioned have gotten tested by EPA and meet or exceed mpg's. So, I guess consumers are driving exactly how the EPA did in those car tests to achieve the mpg, but don't in the MKZ. I won't post on this topic again, because obviously you don't care if it is realistic for the MKZ to achieve 45 mpg and you do not believe that it is false advertising either. Which, I think is absolutely crazy. As a consumer I expect to get EPA ratings, just like every other car. I know most other consumers do too (as does Consumer Reports), except you of course.... Pretty funny!
