Roof taper looks much, but it could be much more. Inside heigth 1950mm is limiting not to taper more...


The 20mm Vacuum formed part protect the side of the van for hits. So its easier to change than to start repair the composite side of the car. On the lower there is aluminum profile which is 20mm offset. usually that is lower 600mm of the van have the most crashes so that takes out the most what bad drivers can give. On some occasions the ground is not level and the upper corners can also touch some obstacles. You can also install your company decals easily to that part centre.

For the computer I think its not any different than any other steering wheel part. It just need to disappear from there when bag explodes. That should be possible to engineer easily IMO.

At this point all ideas are welcome what to improve and how to make it function better.

Vekke, are you sure that the template is placed over your Paku body fully correctly? It seems like it might need to move forward a bit. I can't tell. Is the peak of the template at the point of the Paku's greatest roof camber?

My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

yes. zero line is there where the template is positioned now. It will have cut line there where front and rear will be joined together. Rigth after front fender rear edge.

New video is out. I start to like the nose design so we are getting closer to final shapes:

I've thought the same thing about incorporating some sort of motorcycle swingarm suspension. Use a fully enclosed belt drive for low maintenance.

Add air bags so that it squats even further when stopped. Give it a 2 piece tailgate. The bottom would drop to a ramp. The top swings up. This would allow easy entry for wheeled items.

What's a Vesatiainen?

You've put a lot of thought into the exterior design, down to the windshield washer access panel. I think it's all wrong, but that's just an opinion. Everybody's got one of those.

Let's address that first. VW designed the Type II front end and then put it into a wind tunnel and went to a half-circular plan. It made a tremendous difference in the wind tunnel. How can you improve on the Type II? I gave it my best shot but I can't access my albums. If you can, it's titled 'localmotive' in 'Photoshops'.

As for the taper: The Template posits similar taper on the top and sides. If you follow the Template in elevation but not plan, it will induce rolling vortexes similar to the Cybertruck. Use the same taper on top and sides.

I suspect the side protection is too low. Don't bumpers need to be at axle height?

Powertrain: If you could access Yamaha's offering it would be worth it just for the sound. Another possibility is ZF:

insideevs.com: ZF Presents Its Electric Advanced Urban Vehicle

They offer torque vectoring for urban maneuvering.

On to the important stuff:
  • What's you pathway to production?
  • Why not an unpainted Stainless Steel folded monocoque floorpan with a composite superstructure?
  • Tambour door vs lift gate?

Vesa Tiainen is my name and Vesa Tiainen – Passion for Engineering & Innovations is my engineering portfolio page.

At the moment I am doing the pre engineering. After this need to get the project team together. Currently missing sales and marketing experts and someone with better understanding on the financial and business side.

Rough project plan for the first protos:
- Pre engineering (almost ready)
- team
- Financing from investors and main partners aka the end users
- proto engineering and built phase
- Own testing and testing at the end customer

-->next loop and bigger production volumes steps. Project needs some big external partner to help with the part production and realiability of the powertrain. Thats why best option would be to use some already existing system like BMW i3 powertrain is high propability to be used in the first protos.


More detailed part engineering will be done after we have got a end customer who tells more details about the delivery process. It dictates some of the shaped also.

At the moment options for the rear door that companies use is that sliding door which it has now or two piece normal hinged door cutting line at the centre vertically. Ramp idea is good, but again need to ask the end customers is there is enough space in normal driving to use that. Loading will be done at the main warehouses where there is loading platform.

Rear body will be made novel production ways. If it works well it brings some competitive edge. If not some more common ways of production will be thinked.

Tried to contact also ZF. Nothing so far with them.

Having professionally schlepped much packages and bulky objects in and out of medium sized vehicles, forget the ramps. They get damaged easily, tend to jam going in or out and there is generally no room to deploy them when parked. Lower the floor instead.

Thanks. No disrespect intended.

The site has been repaired so here's the picture I couldn't access:



The design is lifted from an art deco locomotive. It's a Jaray two-body approach, just slid to the front. The sketch is rough, but it it keyed to the Type II's external door hinge line. Holding the width through the front allows front skirts without narrowing the front track.

The lower square front edges induce vortexes that re-adhere the airflow. Elon Musk stole the idea for his CyberTruck.

The dividing line is just painted from the back of the doors to the boat tail. A boat tail might not be fit for your use case. You could use doors the hinge on the side instead of the back so they can open 270°. They could be thick enough to hold shelves or be a box cavity.

The old Citroen vans had three-piece gates. The top hinged up, then there was a split-gate lower.
