I'm looking to eventually start converting a 94 honda civic (manual) to electric. I want regenerative breaking so I'm thinking AC motors are a must.

The way I would like to do it is by having 2 small AC motors hooked up to the axles. the reasoning behind that is I could in theory measure how far the steering wheel is turned and making the outside wheel turn just a little bit faster than the inside wheel. MMmmmmm cornering.

Now from what I understand that would mean 2 ac motor controllers, and a little bit of programming by me. I'm not sure how feasible this is. It's just an idea I think highly of right now

Alternative options: Once larger AC motor and replace the manual trans with a differential. I haven't really seen much of this besides the audi metric mind is in the middle of converting. not even sure what ratio I would use. If i remember correctly he is using 5:1 or something like that. I wont have 4 wheel drive and a really expensive setup like him so I'm guessing I wont have 1/4 torque of his setup.

last option: one AC motor hooked directly up to my existing manual trans. easiest solution, but I dont want all that extra weight and I'd rather not shift

Anyone have any ideas about what size ac motors I would use for these scenarios? like what kind of continuous HP and RPM I would need.

I'll prolly go lead acid batteries unless I can scrap together enough for lithium. I'd even trade off some mileage for a smaller lithium pack to save on weight. I'd rather the car feel a bit zippier and corner well then have it capable of going 100 miles.

My work is about 18 miles from home. Anything farther then that and I'd just use my dino juice sucking car.

Thanks in advance for any tips or suggestions you might have!
