"From all accounts I have gathered, the car Pogue tested, was stripped down - drivers seat and the heat exchange device were all it carried. He kept his speed to about 40 mph. Does this sound familiar? It sounds like hyper-miling to me! The device may have worked, but not to the extent he and others have attributed."
I was under the impression that Hypermilling was taking the car out of gear and coasting as much as possible.
Still I believe he was able to get a claimed 200 MPG in a older heaver car, even stripped.
