Top Speed124 MPH (199 KPH)
Motor/Controller won't be delivering peak power
(125 kW) until about 80 mph. According to our
(crude) analysis it should be gearing limited at
8000 rpm, not power limited.
AccelerationAbout 7s 0-100kph time. Motor torque is similar
to stock engine torque peak in 1st gear, and
that will hold constant up to ~40 mph.
Range140 Miles (225 Kilometers)
Back of the envelope, based on 37 kWh, 6
km/kWh (about what others E-Spits are getting).
May be better due to direct drive, may be worse
due to weight.
Watt Hours/Mile260 Wh/Mile
Assume about the same as other Spits.
Seating Capacity2 adults
Curb Weight2,140 Pounds (972 Kilograms)
Weight with almost all components in place or in
car. Very light frame/body, no frills or
creature comforts, but quite a lot of battery.
Tires175/70 R13. May go to smaller diameter to
increase acceleration.
Conversion Time14 months so far.
Conversion CostGetting motor, controller, and batteries for
free. Cheap non-running donor. $10k in.
