Diagram: How to Ecomod Your Car

[ChazInMT]

I can't recall it right now and it will take some searching...maybe someone else has it at their finger tips. But, there is an illustration out there that shows the rear transition area and relates it to the radius of this area. It basically showed that the greater the radius of the "Top of the back glass" area, the more aerodynamic it was. Since my Civic has a large radius, I figured that was giving me the best aero performance short of a full Kamm type thing.

So, I think the question of whether a partial Kamm will help or hurt depends on the initial design of the car. Civic..Not so much, 96 Tempo....prolly will help.

I think Hucho,Jannsen,Emelmann,Buchheim,and a bunch of others were involved with streamlining on the Golf/Rabbit/Jetta/Polo,Quantum,etc..In their drag tables you see that the lowest Cd is achieved when the squareback roofline is relaxed down to the subtle curvature of the K-form.
It's always lower than a notchback.If a notchback is converted to a K-form roof,it can achieve the lower drag.
If even lower drag is desired,just extend the rear further rearward,bringing in the sides as well as Hucho personally oversaw with Jetta.
From there it's just plug and play for lower Cd.

Sven7 -

Fantastic work! I'm gonna make a laminated copy and leave it in my car to show people. You'll get full credit, of course.

Nice job, Man. I've always been envious of people that can draw well.

Should there be and arrow from the end of the alternator kill switch description pointing to the deep cycle battery instead of the ... , or is it just me?

That is awesome !

It would be cool if that image would be interactive; as in redirecting to an actual real-life example by clicking on any "green-highlighted" zone. I vote for making it a sticky as some people are way more visual.

Thanks everyone for the comments. I have to admit I traced the Civic to save time, though. Perhaps later on I can make the necessary improvements and mayyyybe even do some sort of interactive document. That would be difficult for me though so if someone is fluent in dreamweaver i might need to ask you a favor

I'm thinking a stop motion GIF would be cool. I could walk around the stock car, stop on a part and photoshop the mod in, then explain it and move on to the next one. Not sure if this would be too large of a file though.

Love the art. Was just yesterday outlining the "lowered cost" approach on vehicles to another, and, if they reply with interest will link to this: See, it isn't as drastic as one might think! A bit here and a bit there . . choose your approach.

Great idea Tyler! It is a nice visual aid. Thanks for posting this. If you have acces to a video camera perhaps a YouTube link would be a quick way to put this together.

It is a very nice piece of work. Thank you!
