After much pondering, I have decided to embark on a unique project: to build an electric Spider.
Why the Spider?
The Spider is fairly lightweight, fun to drive, and readily available. Also, I have a thing for Alfas… Here in California, post smog (1976 - newer) Spiders are easily found for reasonable money.
To build a show-quality electric-powered “greatest hits” series 2 Spider.
Increased performance compared to stock.
Netgain Hyper9 A/C motor/controller. Output: 120hp-162 lb/ft torque.
Retain stock transmission, driveline, diff.
Motor weight: 120lbs.
Max RPM: 8000
Batteries: 38 Nissan Leaf modules. (18.4 [email protected]
Battery weight: 320lbs.
Range 50-70 miles
The goal is to make this car fun to drive. The horsepower and torque numbers are better than stock, but because of the motor's torque curve (160 ft/lb) available at 0 rpm, it should be really quick off the line.
The donor car is a 1978. It was complete and not rusty (other than the spare tire well). It ran and drove well and I was able to sell the engine and exhaust system. The car was fairly well maintained, but it had a cheap respray and the interior had been fried by the sun. It has a relatively nice top. Because of the shotty paint, this car is going to need to be stripped down to metal.
The interior is going to need to be completely refurbished including carpet, seats recovered, door panels etc.
Luckily, I was able to test drive this car and the transmission shifts nicely, rear axle is quiet, brakes and steers straight.
Step 1: dismantling
I was able to sell the engine easily because I could verify that it ran. It is amazing how much of the car can be removed when you don’t have a gas engine. All of these removed parts will help the car maintain its stock weight.
