Anybody else reckon that this Scorpion looks to have been more than a little inspired by the Vortex (1990 ish) ,both in looks and concep, ie plywood monocoque and Spitfire front suspension with M/C engine in the back?
A rebodied Vortex......, I agree with you on the concept, it looks too similar......Edited by fuoriserie on Tuesday 24th February 15:23

Piaggio scooter engine range.......just look at the 850cc v-twin option...), I can see a lot of potebtial for a few design projects with that engine......, you could even have a two seater option.

The TREV I covered in the magazine I was editing a while back. Flossy will have a copy of it I'm sure. This and the VW will be the sort of vehicle I can see people using in a few years time as commuter cars I'm sure. Especially now that GW Bush has been ousted from power. The whole direction will shift from luxury 4x4's and sports GTs to economic frugal transport. electric and hybrid will become more and more commonplace too. In some respects the VW video of their vision of the future is right. We will consider cars in a much different light to how we have viewed them to date. It's been hapening particularly in Europe for the past few years and it's beginning in the USA too. The super mini/subcompact is selling well. The Mini and Smart certainly put the kudos in these vehicles and the PSA Toyota colaboration with the Aygo/C!/107 is selling extremely well.
If someone comes out with a cool 3 wheeler the same thing could happen there too. I speak to so many people who look back fondly to the days of the Mescherschitts and Isettas
I agree with your thinking and that is why I believe, we're just at the beginning of a shift in our buying habits,and in the type of vehicles we will be driving in the future.If someone comes out with a cool 3 wheeler the same thing could happen there too.

We will be asking questions we would have never thought of, just a few years ago,like: do we we really need 3 cars in the garage ?, but instead have only a big sedan for our weekend trips, and insted use an economical, lightcar, being it a 3 or 4 wheeler, for our daily commutes.....and a sportscar for our trackdays.....
Price will be an important factor when deciding to buy these type of vehicles......inexpensive should be the aim.

That's cool! A bit overly complicated, maybe, but I like that. (not the over-complicated bit, but the general design).The future of mobility in accordance with VW's views

We experimented with the honeycomb composites years ago building blast walls for offshore rigs. There's an increadible range of materials like this you can use but they are seldom cheap.
I did 4 years of post-grad research into, and design work on, honeycomb structures, mostly aimed at aircraft engines. If you want to know anything about them, please just ask here and I'll happily get involved.Would the extra strenght make sense on such a small vehicle, and would it still be a lowcost project in your opinion ?
Thanks

You would have to go for a monocoque design.......but that is for 2028, I would like to have something for 2010, if not sooner......
I don't see why you can't approach a monocoque design - GTM have successfully been making them for donkeys years for their kits, on something so small and light I see no problem at all. As I mentioned earlier my own design is basically a monocoque comprising of an inner and outer shell filled with eurothane foam. Cheap, cheerful, as easy to produce as a bodyshell.I like the idea of a monocoque, but the impression I got was, that it was going to be costlier than a simple stessl chassis........but I could be wrong.
I would think that a monocoque would be a clean and neat package if done right....

What is the brief here though?
Low volume specialist supply
To go into manufacture at a 'kit-car' level is relativly painless in cost and space.
One problem is when the vehicle is a sucess! expansion can be a real pain when you are in full flow.
My dream sketch of the exploded car above is of the kit-car level.
I too am very enthused about such a vehicle. I have the workshop and equipment, just full of race cars atm.
Be clear in 6 months time...
I would think that this idea, would have to start at a kitcar level...and if things work out for the best, at a later stahge, look into other options and solutions.Low volume specialist supply

certainly the steel (or alloy) tube frame is proven and simple to mace.
A f/glass 'composite' bath-tub body is equally simple and well understood, and looks good in body finish gell coat.
Beach buggies come to mind.

I would think that if you started to warrant moving from Kit car type to something a little more productive that you would be wanting to look at upgrading any design anyway. At the size we are talking maybe move from hand lay GF up to a blow form plastic etc etc etc.Low volume specialist supply or 'Smart Car' operation?

Basically what I'm saying is I wouldn't base any design purely on large volume at this point

Part of me sees 2 models here on the very same chassis and lower tub section: a 'tall' body as the original design sketch and a much lower slung 'racer' body, lowered suspension etc for the younger/more adventurous types, but that might drift us off the main focus here but it opens the market wider.
(Ah! that is what Smart did too!!)
Graham you're reading my mind.....(Ah! that is what Smart did too!!)
, I've decided to go for the low slung racer body first, because from my research in Italy you would have plenty of 14yr. kids looking for something fun and cheerful, that would be safer to drive to school than your classic 2 wheel scooter.....with the added value of a canopy for your rainy days.I'm also counting on the parents view and advice when buying a 3wheeler for their kids.........
The Bubble roof design concept, is more in tune with the adults niche market, and from my research, older people would love to have one.
Your typical buyer would be older people that can't drive cars anymore, due to old age or maybe because they don't have a licence anymore, and a similar vehicle, that doesn't need a licence in Italy, if it has a 50cc engine, is perfect for daily errands to the supermarket or other.
You would also have the womans niche in Italy, especially those that never got a car driving licence, but still need to move around, go shopping on a regular basis, but live in a far away village from the big city....and this niche would need , maybe a two seater design, or something similar.
So you're right in thinking at different niches,

I looked into the fibreglass option a few months ago as I was considering manufacturing an electric kit and wanted a body.
The people I spoke to were very helpful and actually make the clamshells for a well known sports car manufacturer. The cost of a full body mould that will produce hundreds of bodies is around £30K (depending on size) plus the cost of each body. They can make a plaster mould that will produce 1 or 2 bodies for prototype purposes for around £10K.
Don't rule out plywood formers and foam/wood veneers as used on model aeroplanes. They are very easy and cheap to make with home tools. Once covered with an epoxy coating they are very light, strong and easily glued together with epoxy resin. You can make very nice curved shapes with them.

Making a buck yourself can cost pennies as long as you have time, and making a high quality mould from that buck costs not much more. Just needs a bit of knowledge and a dollop of skill Edited by fuoriserie on Thursday 26th February 20:32
