It is cool and it is intriguing and I hope it works but geez that low baseline number is like waving a red flag in front of a bull.

I know unsubstantiated reports are next to worthless but these Mustang owners report about what my Falcon/Mustang owner friends do.

Not rebuilt many miles on the engine - usure of how many rollovers at least one.

I would get 17 mpg city, 24-28 mpg highway

I can't tell if post 1 is from real data or projected results.

The fuel savings (or increase in mpg’s) is approximately (5/14.9 x 100%) 34%. In order to account for energy lost to heat, couplers, drivetrain etc., an electric drive system efficiency of 70% for the home built vehicle is likely appropriate. So a true mpg increase is likely closer to (34 x 70% eff.) 24%. Not too bad for a system that might also add 10 – 50 hp when charging more frequently!
Ahhh, but the above is all conjecture at this point. Shades of Zoltan a little bit... No performance data has been collected. Perhaps it has not ever been activated yet at all. One thing the above projection omits is how much less efficient the ICE gets at lower and lower percentage loading i.e. all the same arguments we went through re: Electrocharger. Toss in the inefficiency of using the ICE to charge batteries instead of roll it all down the road as well (also discussed here at EM). Also wondering if that 5 kwh is for what DOD?

Brucey might be the guy who can shed the most light on this sort of thing, as it sounds strikingly similar...
