In model boats, people just wrap copper pipe around their motors. Despite the relatively small contact area, it's very effective. Could maybe add some conductive epoxy to help a little more.

Yea, someone else mentioned something similar, but can that be done with the existing side glass in place?

In either case, large radius corners should help, but if true then why are the original Honda Insight and all versions of the Prius so sharp cornered?

Is the taper being equal top and side more important than a radius edge?

Does successful execution of one mean you do not need the other?
1. Modify the top curve to match the sides? I'd be more concerned about the drip rail than the quarter windows.

2-4. Excellent questions.

I'd look hard at a Bonneville-style spoiler before messing with that nice greenhouse.

In the GTI w12-650 example the black bubble top would be the existing top. The wing could spring off the rear fenders tops. It would be like the unholy offspring of a Dodge Charger Daytona and a Bertone BAT.

That would actually look really good too.

I'm wondering how I would shape such a thing for it to actually be effective...

Yep, I've seen setups that basically had a full sleeve around that had water flow through it, basically a water jacket. Never tried conductive epoxy before, but I suspect it might become a problem if he has to remove the motor for some reason, whereas the copper coils would be easy to remove.

Maybe just salvage an old liquid cooled PC and coil a loop around the motor?

As I understand it the Bonneville style rear deck spoiler, it must fill out the aero-template shape (see small image attachment - bottom), and yet you still do not have the efficiencies of air attachment.

I agree that it is a shame to mess with the greenhouse, but do not see a way around it with such ambitious Cd goals.

Lowering his lofty aspirations is the only real alternative, isn't it?

Personally, I like the car the way it is and would not change it's looks. However, it's not my car.

NOTE:

Speaking of my own car, I studied a version of a raise Bonneville plane, it just happens to look like a wing but is not intended to act as one. This identity confusion may have prevented others from understanding my intent.

See attachments.

Perhaps such a device could be used on this Triumph.

NOT MY CAR:
https://ecomodder.com/forum/showthre...ler-34390.html


https://ecomodder.com/forum/showthre...e-36229-3.html



Image directly above is different designs to illustrate template fitting.

One might call the two images above that (using Sponge Bob) a raised platform Bonneville spoiler plane in lieu of the more traditional one seen on the Corvette (far above) that is simply an extension of the trunk plane with perhaps some winglets to contain or delay vortex swirls.




EDIT-2:

I found another thread were people were discussing similar concepts.

Flat Bonneville-type spoiler
https://ecomodder.com/forum/showthre...-14946-12.html





Once again these examples do not maintain constant air attachment and are considered less describable than full Kammbacks.

EDIT-3:

Same idea, just not done real pretty.

https://ecomodder.com/forum/showthre...ler-14946.html


A more graceful example.

Because production cars are designed under a variety of constraints, like maximizing interior volume, achieving a certain minimum headroom, having adequate space for side curtain airbags, and doing all that while minimizing cost.

That is part of it, but Volvo seems to of worked a little different formula so it certainly isn't mandated.

Going back to the wing that isn't a wing idea I was exploring on the Porsche and evident on the Ford Escort RS, exactly how less effective is it than a Kammback?
