There are a couple issues I have with this.
1. It is a mistake to only look at highway numbers. All the manufacturers are doing that now on the commercials but it is not a realistic, nor entirely honest.
2. There's no substance to that article. Who has independently verified any mpg claims? People making claims are a dime a dozen (see fancy spark plug threads).
3. Aside from getting everyones naughty bits excited, what's the point? Ok, maybe that one is rhetorical
