So far I've got the car. The plan is to replace the 1.3l ICE with a three phase AC motor and Life battery pack. Hopefully the result will get me a top speed of over 100km/h, easy cruising at 80km/h and a range of 60+ km.

Photos and more info to come.

The parts are slowly coming together. The controller is here, the motor is being rewound and the batteries have just been ordered from China. There are still many problems to sort out, which is why I'm so glad to be a member of the Australian Electric Vehicle Association (AEVA), Brisbane branch.

Picked up the motor yesterday. I think a baby blue motor will look good under the bonnet.
