The idea isn't totally without merit. .. I was at a local boat show a while back and saw a conversion system for pleasure craft (ie a boat big enough for me to have a real party!) using the classic GM 6.2 to drive a BIG
alternator and that drove 2 watercooled AC motors. Also provided the juice for unlimited lights and audio
I do't know what your goal is but have you considered a parallel aka "thru the road" setup? IIRC it takes about 25 hp to drag 7 along at 65 or so, use supercaps and an electric booster motor on each front wheel for acceleration. 35 hp ought to be enough to keep the caps charged if its a booster only function and run the car at 75+mph, Jack did it with MAX on less. ..
Fire the Boosters Mr Scott!!
Now that could be a handful of go fast button!
Re; controlling a dual motor drive(assumed to be DC), the overrunning tire loafs and you get dragged thru the corner on the inner tire IF you wire the motors in parallel off of the controller output terminals. Voltage= RPM. .. Motor specs include rpm/volt ratings.
So off you go down the road,the outer tire running at its programmed (typical iirc) 72rpm/volt and oohhh 72 volt so 5184 rpm
as is the inner tire(needs some baby coach wheels with those rpm!).
Then you start a left turn, the outer tire has to cover more territory due to the constraints of the axle/chassis/duct tape but it can't provide additional thrust above its voltage determined rpm so its coasts drawing very little amperage.
Actually you get a teeny tiny bit of extra juice at the inner tire ( parallel wired remember?) when the outer tire begins to function as a generator by being put into overspeed condition (I don't recall exactly the minimum average needed for a usable gain in power provided to the inner tire but it was somewhere ~13% overspeed).
