Has anyone built from scratch?

Hi. I'm fairly new here and have been fascinated by the wisdom and information available here. I am, however, intrigued because there seem to be very few people building from scratch and those vehicles which are aren't usually for road use.

I reckon that if a car were build from scratch and some concessions were made to the necessities of weight, rolling resistance and aerodynamics, and one modified one's expectations of what the car could do (i.e. accept that there is limited boot space etc.) then the performance and range for a given elecrical setup could be significantly improved.

I've built a few vehicles and reckon (if using LiPos) that a 2-seater vehicle could come in well under 300kg without passengers, if not close to 200kg and have a CDA of under 0.2 if well designed.

Has anyone tried to build from scratch or have any advice on such a policy? There must be something I'm missing.

Thoughts and inspiration welcome

It's something I will probably do eventually, but I'm working my way up to it gently. The plan you've sketched out is something I think a lot more people would do if it weren't for the practicalities/perils of coping with existing traffic. Personally I think most cars are at least three times as heavy as they need to be, given average speeds (in the UK), but no matter how much I curse SUVs and pickup trucks, people keep on buying more of them. Having built a recumbent (pedal) trike, and converted a motorcycle to electric, I'm now converting the smallest car I could find (an old Mini), as it's the best compromise I can find.

Your plan sounds good and I love the yellow streamliner, but if you're serious about reducing weight I think the hub motors would be a heavy choice. Better to use a lighter, faster-spinning motor, or motors, mounted inboard with a single ratio reduction.
That's a very professional job Thumper. Did you make up the motor to transmission adapter yourself, or is it an off the shelf piece?
