thats pretty similar to the one i built several years ago

I was just kidding. Whos helping support the project? Any manufacturers? I have looked into drives (motor and controllers) before similar to those used by AC propulsions ala T Zero car. All I can say is expensive. Still has totally disuaded me though. One day I'll get something moving with LIPO batteries or something..

It will be ran by an EMU12/E generator powered by a GTP30-67 gas turbine.. Or simply an APU or GPU whichever term you chose to call it. I have yet to purchase the high output high torque electric motors, but I have already purchased the APU.
I’m still deciding the drive train system layout. It’s to be AWD but there’s a # of ways to do it. It will also be wired for regenerative braking. All while being 3 times more efficient than my rx-7 could ever dream of and being able to run on almost any fuel. Just picture a electric car but with an onboard recharging system primarily for long range. Nobody is funding it. Just me. I calculate a 0-60 speed of under 3 seconds and homefuly 3 g’s of lateral acceleration and deceleration.

That’s a video of the aerial atom electric car some guys converted.. Shows it smoking a Porsche carrera and a ferarri 360 modena with little efford in the 1/8th mile and as you can tell at the end it is still agile as can be for the backroads and maybe autocross or something funer than a straight line. Its powered by 1 electric motor and is rwd.

I have seen some concepts with hub/wheel motors. Except for the addition rotational mass, and unsprung weight I always thought a setup like that with 4 or 2 motors would work best. You totally remove the drive train losses. You can effect have no brakes, though you might need some small system. Fun stuff.

Just so nobody get the wrong picture. It won’t look like a normal car or drive like one. I’m my designs on Autodesk Inventor I’ve integrated the look of a stealth F-117. The driver will sit in the middle of the car and the passenger behind him. The inside will look like a cockpit and the canopy will look like that of the jets... all body lines will be creased and have no contour just like a real stealth jet. The gas turbine will be behind the passenger seat.(behing firewall) The canopy will also open up like a jets verticly… it will be painted black and the whole car will be about 40 inches tall.
Now picture a hydrostatic garden tractor. You have a throttle lever for the engine rpm speed and the big lever is for the ground speed. (Forward reverse and neutral with 1 lever) that’s how it will be set up. To slow down you can simply pull back on the lever a bit to cut the power then regenerative braking will automatically kick in. of-corse I will have real brakes and a brake pedal on the floor for sudden stops: D and being able to liscense it as a kit car.. real brakes will help with that..

ahh exactly, thats why i want 4 hub motors instead of 2 motors (1 frotn and 1 rear) that run into a differential. although 2 motors with 2 diffs would be much simpler hmmm.. it will be a very interesting feeling to not have to shift and to never have to rev. having absolute torque from standstill is like reving a big block v8 and dumping the clutch except.... instead of doing that u semply smash the gas

oh, and why 5-lug hubs???
why not FC 4-lug??
arent all FC discs the same specs?? (other than bolt-circle)
and if not.. I know the CARRIERS/casts are..
so you could use the 4-lug hub assemblies
and then have 5-lug discs re-drilled for 4-lug.
um, what rear assembly are you planning to use??
FC steering column..
why would you want one of these??

Gives me more coil over options, rack and pinion, bigger brakes, better geometry, oh and I'm addressing the ride height issue....
The lower control arms are for modifying and using on the road car as uppers.

OK so the FB column will connect up with no issues, thats cool and easier...thanks Chuck, I have a sub frame and rack, but still need 5 lug hubs and calipers, or I may make those Wildwood calipers work if I can get an adapter made to fit.

I wouldn't waste the time, at least now..on the wilwoods, just throw it together with OE stuffs... brakes etc..
ok, about the column.
no, the two don't connect..
you'll have to fab something between the two..
no worries here.. get the sub-frame mounted.. with the rack and all.
then look at the two... and make/machine a link for it.
it would essentially like a mini-drive-shaft.
Mmm yeah.I almost wish i could get back to developing/playing with mine...

well it could if it was doing more than just rotating...
it would be transmitting steering input from a fixed steering shaft.... to a fixed steering rack..
the reason drive shafts bind is because they are moving laterally, and vertically, reletive to the chassis.. while rotating..
