Good morning new friends. I've been kicking this idea around for awhile and now I'm here to ask the experts if my idea is feasible. Keep in mind, I'm a decent shade tree mechanic, have built a couple engines and even an automatic transmission but still consider myself pretty green in the overall scheme. I have ZERO knowledge of electric motors and electricity in general but I'm willing to learn. Here's the skinny-
I have a 1981 VW Rabbit 1.6 n/a diesel I've been driving for the past few years. The whole time I've been using a 50/50 blend of diesel and WVO. I average 45 mpg. I have about a 20 mile trip to town, 90% highway.
My plan isn't to totally convert to electric but rather make a hybrid. I would use the diesel engine to drive to town, then use electric in town. I would be happy with a top speed of 40mph but faster is always better.
Obviously the Rabbit is front wheel drive, the rear wheels are just back there, doing nothing, just rolling. My idea is to install an electric motor to drive one or both, OR a pair of motors to drive both wheels, depending on your guy's recommendations. Seems to me a (insert correct term here) motor, with a shaft going all the way through it, mounted in the center rear of the Rabbit with a couple of cv shafts going to each wheel would be the cleanest install.
The car is a real piece of crap and I have a parts car as well so I'm not too worried about cutting stuff up or whether or not I'll ruin it in the process!
I'll admit, I have done very little research, but it appears with the right motor selection I probably won't need a transmission, especially with my goal of 40mph. I was also planning to use 4-6 12V batteries to power the motor.
A couple things I'm worried about-
With the motor(s) connected, what will I see when I'm using the diesel engine going down the highway? Will it create a major drag? Will I over-speed the motor(s)? If so, I can always create a way to disconnect the cv shafts if I have to, not that I want to.
Actually I guess that's all I'm worried about right now!
I have manual steering, manual.. everything really so I'm not worried about driving around in town with the engine not running, transmission in neutral.
Go easy on me, but please dissect my plan and give me some pointers. If it sounds like it may work, this will probably be my build thread.
