Hope it is true, but DON'T BELIEVE IT !

Only time will tell if such an engine is really possible. The sad thing, if it is, that it will probably be years for it to be mass produced, available and affordable for the average person. It may be a long term solution but I don't think we'll see the benefits in the immidiate future.

No way would it be possible for an engine to created 400 horses but get 80 mpg. If an engine could do this their would have been an evolution of engines. Let me explain, every technology increases overtime. You cannot just go from any engine that gets at best 15 mpg and create 400 horses to an engine that create 80 mpg and creates 400 horses. If there was any engine that could do this there would have been an engine that could get 40 mpg and create 400 horses. Unless this guy is an utter genius and has invent a totally new engine made from Alien technology that he bought from Obama's Frienge (I hope the is how you spell it) relative. I could understand it this guy comprised on the horses the save on gas, or used something that save like 10% on gas but still got the same horses.

Wow, it would be wonderful! I wish they had gone into more detail but I agree that there would have to be a complete restructuring of the internal combustion engine as we know it. It would also be fantastic if it could be a flex fuel engine as well. If this turns out to be real then he will be a genuine American hero. More power to him if he pulls it off. I guess we'll see.
