You cannot beat internal combustion engines and fossil fuels now or any time in the next 20 + years given current technology and sustainability.. Factor in pre-production emissions and the gap widens more... The only attraction to hybrids and plug-in/electric hybrids are gimmicks paid for by tax dollars.. What do you do when your a high earning middle class folk that don't get a tax break?? You buy one!!! Anytime an energy is transformed or transferred you lose energy in some way via heat or friction.. Cannot beat Newtonian physics... Hydrogen power?? Dream on!! No way to make it happen reliably or efficiently in an auto.. The technology to pour distilled water in a tank and produce hydrogen that will propel a car down the road is a fallacy.. Hydrogen sucks also as far as stored energy goes...
