I don't think a Subaru, other than maybe an old justy would be a good candidate for this. Between the weight and the AWD, it would take a lot of energy to move the car. So you would have to put a lot batteries in the car, and still have a very limited range. I would convert an old civic hatchback, or another light 2wd car.

It's certainly possible, though I agree with the earlier posters that the outback is a lousy platform for conversion. Heavy & draggy with AWD.

You're starting with a payload of 900lbs. Losing the gas engine and (full) fuel tank would increase that by about 375lbs. A reasonably-sized lead-acid battery pack would weigh around 500lbs with the expectation that it could get you 80ish miles of normal driving with an 8-hour recharge. A pack like that would run you around $2000 with a suitable charger. (I'm using reference numbers from T-105s, assuming 8 of them)

An electric motor with torque similar to your gas engine would run $1500-3000 and weigh around 120lbs. Figure on more weight for the motor controller, and accessory adaptation. You'll have to figure out something for heat, air conditioning, power brake assist and power steering. Maybe just skip all.

With the weight up to that point already, I'd suggest gutting the rear seats and putting the batteries there, since you've already taken up much of the payload that the 3rd & 4th passenger would otherwise enjoy. Also it puts that mass right in the center of the car where it balances well.

Then you'd get a fabricator to make up an adaptor plate to mate the electric motor to the input shaft of your transmission, adapt the accelerator pedal to the motor control input and you're sort of there. Gross oversimplification, I realize.

You could probably improve things a lot by abandoning AWD: dump the original transmission, mount the electric motor inside the trans hump and connect it directly to a propshaft powering the rear axle. Let the front wheels ride dead, and then get the whole engine bay as space for your battery pack. This does nothing to solve the heat, AC, power brake or steering issues but you'd be able to keep the interior intact and be able to carry passengers back there as long as they don't have luggage.

All in all it sounds like a decent $8-10k project.

they had the R1e in Japan.

And there was a converted Sambar on craiglist (or ebay ???) that was done by some g'mint entity.

if you could cut the engine down to 2 cylinders and squeeze a motor/generator in between the engine and transmission, that might be a cool hybrid.
