what about the new(ish) continuous drive transmission toyota is using? i'm not
entirely sure five big magnet and/or coil sets would be any less weight than a
single front drive transmission. there would have to be some colossal energy
density to get small enough motors tough enough move a car and yet fit inside
the wheel, (although it does make for some interesting controlled braking
possibilities, especially for cross country races).
on a side note:
is there any way to use CO2 pulled from the air for a materials carbon supply?

2500 lbs seems a bit heavy. My old pickup truck only weighs in at 2,600 lbs,
empty. With fiberglass and carbon fiber, it should be possible to make one
that's closer to 1,500lbs or less including engine, everything. Wonder if it
might be less weight to do a series electric drive system and get rid of the
transmission entirely. A high frequency high efficiency generator would
operate from a fixed RPM operation of the diesel engine, and a variable
frequency drive would directly drive each wheel. No axles, driveshafts,
differential, gearbox, etc. And the engine is still always operated at the
highest kWh/grams point.

i propose a new fuel economy goal. 100mpg @ 100mph!
any design ideas? i'm thinking a 4cyl UHC diesel engine with at least 10
forward gears in a vehicle body weighing no more than 2500lbs.
