From the front, a regular, non-aero box Grand Prix:


But from the rear, aero! Sort of.


And look at that useless trunk opening because of it!

These cars were homologated for NASCAR competition,to compete with the Ford Thunderbird.The rear helped but the nose actually compromised race handling.
Going from the more traditional,formal,notchback,to the AeroCoupe profile shaved 10-counts off the Cd and improved effectiveness of the rear spoiler.

Groovy, but belongs in the unaero thread?

That's a bit harsh. Radiused front edges, taper in plan?

Belongs in my [hypothetical] yard.

What part disturbs you, the giant chin spoiler that might produce down-force?

My only caution is on the chrome bits, if not installed correctly could be sources of drag, but I don't think so.

I'd love to see some wind tunnel or CDF images of this.

That giant chin spoiler-like thing on the front could prevent air from being drafted down over the roof of the tow vehicle in some ingenious way. Obviously it's overkill in that this is not an object that will ever be experiencing free-flow air hitting it.

However, if the tow vehicle is a pickup truck, I think the design even makes more sense.

There could be some lift created by the front glass angled like a tug boat (and roof overhang), but it would all depend on the tow vehicle selection I suspect.

If there is one thing you want out of a trailer, it's aerodynamic stability.

Unfortunately, that usually comes after capacity and as an afterthought.

Set this trailer up on a camping site with a view of a lake, and point those bow windows at the lake............enjoy even if it rains.

Now that drip edge overhang is all the more a stroke of genius.

Hmmm, what would you call an amphibious house trailer?

All it needs is retractable wheels.
