Thanks for that, sendler. Really interesting.

Here is an overly complex setup that allows a very small engine for greater fuel economy: a small, light-weight car, with an engine that is smaller than 1.0L. It would use a combination of a BAS-type eAssist, an exhaust turbo, and a very small electric supercharger for low end torque in the turbo lag seconds. Set up with the ability to harvest heat and kinetic waste energy in a battery with a grid charging ability too... Seems likely to win a Rube Goldberg design award!

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
