here is one that I shot in the pre-start assembly are during the 2006 Silverstone Historics. I have some doubts about the originality of the front fairing...is that the fiberglass housing you were talking about?

yes, that's it

Fairing, shroud, housing--I don't know the accepted name for it, if there is one--that's what I mean.

Why do all the Fiats have open rear hatches? Is it because it needs the extra cooling?

Anyway, cool pics. It looks like an Italian Mini Cooper on steroids.

That's what Abarth wanted people to think, so they wouldn't be inclined to make him close them.

In reality it markedly improved the aerodynamics of the car and increased top speed. A rounded rear, unless you can make it very long, creates a great deal of drag. Look at the "whale tail" spoilers on 911's, for example--they basically fill in the void created by the body as it slopes down, creating a squared off rear. The goal is to keep the air flowing higher and then have a sharp cut off. You will see many examples of this if you look at the cars on the road around you.

Thank you for the information, I actually didn't know it and I believed the official story. I suppose that the Kamm tail is also a similar solution, if different, to this aerodynamic problem.

Yes, it is. The best example is the Alfa Duetto Spider. It looks cool, but when they chopped off the tail and made it chopped/Kamm it produced less drag.

That is true, because they used to have the option of opening it even in the early 850TC road version. But it is also true that the exhaust system on the later versions would make it impossible to close.

So does that mean all the Porsches that don't have a wing or one that pops up have aerodynamic problems?

Not problems really, but if two cars were otherwise equal, the one with the spoiler would go faster. And probably have more downforce, as a 911 is a beautiful car but is basically shaped like an airplane wing, so it will tend to lift off the road at high speed.
