you guys are all talking radical huge engine changes. why not he just used a bunch of the currently available technologies at once put together wisely?
a VTC and VTEC system with computer control could switch cycles from otto to attkinson, displacement on demand could shut down most cylindars when not needed, hot air intake and a couple extremely fine spray injectors per cyl could help evaporate the fuel better for more complete burn, lighter weight pulleys and no power steering or ac and a dry sump oil system could reduce parasitic losses, an appropriately sized and controlled turbocharger could eliminate the loss from sucking air in, variable valve throttle style would reduce throttle plate losses...... now put all that together and refined specifically for fuel efficientcy and then he goes and drives like this website suggests..... I dont see it as bull at all, I see it as a wise combination of various currently available technologies and refined highly, and then with all that there available to control boost pressure and valve timing and height and intake temperature and how many pistons fire for the load needed, you could easily make way the heck more than 400hp, you could put down over a 1,000hp and then with the flick of a button the tune changes to eco and you've got 60mpg, then you drive really smart and shut the engine off when needed and you get considerably more....
