You're not selling a solution to anything, you're selling an aspirational product dressed up in urban transport solution clothes.
I can do a really worthy version for you if you like but if I try and sell it based on it's green credentials alone I reckon I'll sell less than 5% than if we also make it a cool product.
The green stuff:-
The usual electric speil:
* Targeting the equivalent of over 150mpg and should cost less than 1p/mile to run.
* Zero pollution as point of use.
* Charges overnight so utilising off peak, cheap rate electricity which I hope we'll be able to tie in with green/sustainable, wind or hydro or other generation schemes.
As well as those we're hoping to add:
*Small foot print allowing more passengers/piece of road.
* Central drive position, combined with a minimal front width and exposed wheels with front being widest part will give confidence in traffic allowing gaps to be smaller with less risk and allowing (single occupant} traffic to flow better.
* Minimal everything - "just enough" mantra meaning less materials and less waste. We are aiming to be the pretty much the lightest "car" on the road with performance* gains all round because of it.
*Fuel economy/braking distances/agility rather than acceleration or top speed
I couldn't live with 28mph or the lack of a second seat.
The Twizy above looks a better bet to me. I've yet to see one in the flesh mind.
28mph is for 16y/o only - as soon as you pass a car test there's no restriction. 2nd seat fair enough this wouldn't be the vehicle for you, then you'd need the slightly bigger version which will come after.
Twizy is great, a really interesting product and very well done. I drove one last week in glorious sunshine and it was fab but the lack of weather protection will render it a novelty that works best in a Mediterranean climate. It's a modern day Mini Moke.
Three wheels also hits a bit of problem when it comes to road surface, that part of the road untravelled by regular car wheels etc can be a nasty place to put a driven wheel. Add some snow and you have an even bigger problem.
The 3rd central wheel thing could be an issue but we'll have to suck it and see - I'm not discounting going 4 wheels but 3 is the more economical option no matter which way one looks at it.
As I said before, there's a grain of a good idea, but I keep asking why there is no commercially successful independent manufacturer mopping up this market.
I can't either - plenty of the big manufacturers have had a go at producing prototypes but no one has had the ba11s to commit to productionising something - they get as far as showing some pretty pictures and it's never heard of again. There were rumours that Audi was going to release 100 of it's Urban concept but that was 2 years ago and it's all gone quiet. I think the trouble is they're all too tied up with NCAP and the other safety issues to make a viable vehicle
It's 4 wheels and 2 seats and too heavy but it's a fair way there.
If the car you design is as much fun as the leaning tandem vehicle on YouTube then I would be a possible candidate for business use rather than my 16yr old. His need is to get 20 miles to school and back, buses extend his day as of last week from 8hrs out of the house to 10.5hrs which is quite a chunk and down to the vagaries of the buses.
It won't lean but it will be fun - I'll put you down for 2 then ;o)
