Note that the batteries in hybrid cars are charged by the good old gasoline-powered engines and it takes a loss in the transformation of engery. Hybrid technology is only about regenerative braking, which saves just a little energy, at the expense of extra components. And net gain in energy? Zero!!
You can clearly see that Prius used all the tricks in the book for fuel efficiency, it has a small engine, very high compression ratio, a minimal gross weight, and a streamline body. That's how it gets good mpg. The electric components are not doing any good. They are there as an excuse for making smaller and more efficient internal combustion engines, which is very un-American... haha!!!
Plug-in hybrid is inconvenient, but it's honest. Hybrid is not just a novelty, i would say it's a scam. Manufacturers are leading comsumers into thinking that somehow the energy recovered from regenerative braking can do any significant work. Strip the Prius off all of its hybrid nonsense and it would do even better!

Hybrid vehicles are the most fuel efficient models in every category where they are available. The improvement in fuel efficiency with the best systems is very significant. Your criticism is that the batteries don't suck energy out of the air. Well, no shit. Hybrids save fuel. As far as I can tell, that is just as good as sucking energy out of the air.

Bullshit.
First of all, the smaller engine is possible because the electric motor provides additional power to compensate. That is one of the ways that the hybrid system saves fuel. The smaller engine operates at more efficient power levels more of the time and it also saves some weight.
Second: regenerative braking is meaningless unless you have a battery to store the recovered energy and a motor to use it later. It is analogous to saying you don't need that piston engine because all the energy comes from gasoline.
Third: If you want to minimize gross weight, the place to start would be that very heavy and supposedly worthless battery and motor. At a curb weight of 2932 pounds, the Prius looks pretty heavy if you don't consider the hybrid hardware. Minimizing weight hardly compensates for carrying dead weight, so the hybrid system must be earning its keep.
Fourth: Streamline body? Have you noticed that Prius gets better mileage in the city than on the highway?
Fifth: If all of the above plus a compression ratio (13.0:1) were all it took to get 40+ mpg, there would be all kinds of 40+ mpg cars out there. But the only ones are hybrids. Even the Yaris can't touch the Prius. That alone tell you something is going on here.

Seems like those electrical components are doing something.

You misspelled un-Arabian.
