Here's the data sheet on the material. I don't see any spec on abrasion resistance (Very Important!)

I was wrong. The canopy bubble is made from polycarbonate.

Come to think of it, several of the referenced designs by forum members sport two-tone paint jobs. I wonder what their reasons were.

Remember, this is a first pass, on idea floating around in my head, not Tyler's. However if member input hates or likes it, some reasons why might help both of us on future projects.

You can use squares too.

EDIT-2: I looked at the sight lines from the rear view mirror and now better understand the rear glass size. Tyler, go with safety first and sort of ignore my post about it looking too large. If you carry the rear glass over the roof Porsche Targa style, it might make an interesting option.

The Lupo 3L has some kind of early DSG thing - Vekke may be better to ask on this one as he has one. The 1.2 TDI sold in the latest Polo Bluemotion (and Skoda Greenline / SEAT Eco models) is mated to a 6sp manual.

Yep, windshield will be DOT safety glass. Industry standard.

I like those dots! Patterns can look pretty cool, as Renault has shown us. I just am not sure how it would be 1) received by the buying public or 2) handled in terms of crash regulations. Any thoughts on this?

(I hope I'm not being to critical- it's just how I operate. Someone tells me an idea and I throw back any problems I see. It seems to be the most efficient way to figuring out a solution. I don't want to appear blunt.)



The glass roof idea is a neat one but I've seen lots of members from the Southern states complaining about that sort of thing so I think I'll just keep it conventional for now. Plus, glass roofs are expensive! Maybe painting it white would be neat- both heat dissipating and a cool graphic breakup like the glass roof would give us.

However yes, the rear window will stay large. If you look at the VW Beetle, Saab 92-93-96 series and other long-production cars of the era one consistency is that their rear windows always grew over time.

92, 1949-56


[93, 1956-59, larger oval window]

96, 1960-1980

I'd laugh to see someone try to maneuver that thing in tight quarters...

Doesn't look like the template to me.

I did my very rough aero testing with 5 leaf blowers.

If I had done it outside (on a still day) it would have been better; since the air was recirculating around by the end. Leaf blowers cannot get parallel and equal velocity air flow over the model. You really do need a tunnel of the proper cross section and for a scale model the velocity of the air has to be proportionally higher.

Considering how many compact cars and SUV's have their glass within inches of the rear bumper plane I'm not going to worry too much.

Polycarbonate tail, or translucent fiberglass would be no weaker than the regular fiberglass tail of a kit car, in my opinion.

Point or goal of it is, to make it look slick and not dangerous or scary looking. I'm sure everyone will have an opinion of what they like or do not like, and you cannot please everyone, so you have to please yourself.

Oh, but I'm referring to the laws that you need to have the taillights so many cm from the rear most point of the bumper, etc. This is why you always see the bumpers sticking out farther than the lights. Kit cars don't have to meet any regulations afaik

Maybe it's just a decal for graphic breakup. Maybe it's implemented in a different part of the car. Maybe I make some other graphics on the thing. I like the idea and there's got to be a way to implement it safely and legally.

Of course there are ways around it. The V35 Skyline/Infiniti G35 looks flat on the back but actually adheres to the rules. (Also imo one of the best looking cars Nissan has put out in many years)





The rear surface of the Vogn is concave because I read that facilitates more efficient eddies at the back. I'm going to try to work around that, styling wise.

I think the car companies have hundreds, thousands of people who's only job is to make sure government bureaucracy and regulations are satisfied.

Do what you can with what you know, just remember you are trying to hit a moving target with a single shot pistol.

I saw these and thought of Tyler.
