I know there are some cmpg members who will get a kick out of this, and I suspect there are some who already know about it (from the EVDL and other EV related forums/sites)...
May I present my new car: the ForkenSwift

It's a 100% electric runabout, built using parts from a matching pair of junk cars, a forklift and a golf cart, for the princely sum of $672 (Canadian).
As of about a week ago, it is legally registered as an EV, inspected, insured and on the road.
A friend and I hatched the idea to do this EV conversion about a year and a half ago, and dove in not really knowing the first thing about it. But there are so many online resources, anyone with a computer can find all the information & assistance they would ever need to undertake a project like this. All you need is some mechanical aptitude.

Under the hood. (click to zoom in)
The goal was to make, as inexpensively as possible (since this was more or less a science experiment), a LSV/NEV comparable vehicle, something like the ZENN (http://zenncars.com) (but without the 25 mph top speed restriction). The car would be used exclusively in sub/urban driving on the quiet streets of the small city we live in.
Range: we ended up with a car that will go - in warm weather - 20-25 km on a charge to 50% depth of discharge, driven gently. This is on a set of used batteries donated by a EV owner in Ottawa - a new set would likely double those figures.
Top speed seen to date is about 60 km/h (40 mph). Given more road & patience, it would undoubtedly go faster. That said, the car's acceleration is glacial (this is a limit of the motor controller - from a golf cart. We're shopping for a higher power unit :)).
How efficient is it? I haven't gotten into a regular charge/drive cycle yet, but the Kill-a-watt measured 5,100 watt hours to recharge the car after 24.8 km, which works out to 331 watt hours per mile. Compare to Tesla's official energy consumption figures (per EPA methods) for the Roadster of 310 wh/mi (http://www.teslamotors.com/blog4/) (also at the charger). :) Of course that's their official EPA figure, and we know all about those. The Tesla would undoubtedly spank the ForkenSwift (or just about any other owner-converted EV) in a head-to-head hypermiling competition.
YouTube: I've posted a series of videos of the car. The latest, made to celebrate the car's transition to legal EV status, shows the car in action -

The electric umbrella: is another nickname I've given the car. I tend to do nearly all of my local trips by bicycle, except in crummy weather, or when I'm taking passengers or bulky cargo. The ForkenSwift is such a treat to drive, lately I've been looking forward to the rainy days! :D
