Pretty sure this has been posted already, but hey, it's a new video:

I like this because it reminds me of the Mars Direct 3.0 Mini-Starship:


justacarguy.blogspot.com: Agustín Aguaviva's v8 Ford rear engined midget was a revolutionary design, so small that in order to sit in the Midget's seat, he had to remove the steering wheel. An engineering feat because at this time, only the Union cars were designed as rear-engined race cars

A Mini-Auto Union ....in Argentina. No doubt after WWII, the same time similar sized belly tankers were running on the Salt Flats.

Definitely filing this under "aerodynamic oddities" instead of "aerodynamic cars."

Hey, what is this late 60's early 70's American car doing here?




Annnnnd the back



I'd never seen an AMC Marlin before. Like a mullet. Business up front, party in the back. Love to see the drag calcs on this one vs the Ambassador (same front end).

The rear 3/4 view as they drive away is breathtaking.

At least the two tone version gets that reaction from me.

Every once in a while one will show up at the Orphan Auto Show in Ypsi.

And now, some strangeness.

My parents had a 770 station wagon that color. Neither warm nor cool gray.

Argentinians are often pointed out here in Brazil as having some sort of fixation about Germany in general and Nazi stuff. What does surprise me is how Citroën succeeded there with the 2CV while Volkswagen concentrated efforts in Brazil at the time, only entering the Argentinian market officially after buying Chrysler's assets there. On a sidenote, I wonder how the engine position affected cooling in this prototype.

Odds are it was built by a German ex-pat. Like the FMA_IAe_33_Pulqui_II from Kurt Tank.

Most likely, like the Auto-Unions, front radiator and engine air from the side scoops.

In 1989 the SCCA began a program with Carrol Shelby to develop a new single make sports racing car to revive the Can-Am Series. The chassis was designed by Alan Burke and David Bruns, original body work was designed by the legendary Peter Brock and the transmission came from the Can-Am and Indy car gearbox shop of Pete and Chris Weismann. The car was built at Racefab Inc. and went into production in 1990.....................

This is chassis #14 of a total production of 74 cars.................

An interesting use case, an off-road 911. en.wikipedia.org/wiki/Porsche_Panamericana

It featured a removable waterproof fabric top that could be attached by a pink zipper. Various roof configurations were possible and the car was in fact a hybrid of a targa, convertible, coupe and off-roader.[3]

.... In spite of its un-streamlined wheels, its aerodynamic drag coefficient was only 0.30.

It's a [double-]bubble top coupe and a Targa



The air intakes gobble up the roof edge vortexes.



The 0.30 Cd probably comes from the deeper windshield, slant chopped roof and the (Tropfenwagen?/300SL?)-style fenders over the radiused wheelwell edges.
