About the Car

Here is the current form of the car and what has officially been done in the two years of work.

  • Platform
    • 2002 BMW 325xi
    • The car was $600, supposedly a bad engine, with 202k miles. The body was honestly in really good shape, no rust, and minor scratches. No dents, dings, just some worn paint where the front right wheel must have blown out and rubbed paint off.
  • Motor
    • General Electric 9″ DC Series wound motor
    • Peak power: 144kW (198hp)
    • Max voltage: 144 volts
    • Max amps: 1000 amps
    • Current setup: 72v @ 1000a, 72kW (98hp)
  • Controller
    • EPC EP-1000
    • Peak power: 210kW (285hp)
    • Max voltage: 210 volts
    • Max amps: 1000 amps
    • Current setup: 72v @ 1000a
  • Transmission
    • Stock BMW ZF S5-31
    • The transmission is the original from the car, but modified to work in this application. The transfer case is currently forced to output power to the rear wheels only, instead of its intended All Wheel setup. The input shaft and collar have also been modified to be shorter and allow the motor to fit flush against the bell housing.
  • Technology Upgrades
    • The car has had a few modern touches added by myself to bring it up to date.
    • A custom digital gauge cluster using an Arduino and a Nextion touch display. This is being programmed to show the vitals of the car, like the motor RPM’s, battery voltages, amperage draw, and other important metrics.
    • A handmade switch panel was installed in the center control area of the car to allow granular manual control over important elements like the motor controller, lights, dashboard, etc.
