This has lots of potential, but it's just artwork, so it's an oddity.

Looks very un-aero to me.

Sure it's un-aero as it is currently presented, but the potential is there if the latter half has an aerodynamic shell/cap/bed.

The front half and even the wheels and wheel-covers with fairings are pretty sweet.

EDIT:
2005..............it's different, has potential depending on how fancy his helmet will be.

The other change was to saw off the pointy Spock-ear rear wheel fairing tips. I am going to insert a custom CNC cut aluminum cap which will include some high intensity LED lights into these open holes. I also think it looks better without the extreme pointy tip. Now the curve at the rear of the wheel fairings matches the curve on the rear of the main fairing.
Very curious upper rear wheel venting, odd but I like the rocket reference.

That's a lot of axles to carry one race car.

Haha, yes the potential rolling resistance is also quite high.

I like the Syd Mead influences of the illustration and the general racy attitude.

I assume that it is not meant to be taken seriously or as technically accurate, it is meant to be an inspiration, to invoke an emotional response without too much thinking (I'm guessing).

I'm also sensing a bit of Gerry Anderson (Thunderbirds) influence.

A clear plexiglass teardrop bubble aft-cab would have been an over the top effect, but would have transformed it for the Ecomodder crowd.

EDIT:
Here are some oddities, they are not aerodynamic themselves, but when deployed are very unaerodynamic.

We had mention of a flying car at Permalink #94. Here's an interesting one, like something done by Luigi Colani.

With two fans that could be that high-bypass type.

He's moving air, so it is aerodynamically related.

Blower impeller design experiments



I see now why hovercraft use the straight and backward curved for high pressure lift fans.
There are musty old books with pages of experimental results. Dust blowers have straight blades to best handle debris. I'll look it up if anyone is interested, but the old HVAC manuals recommended the less efficient forward-curved blades (IIRC) because they would still move air even if one's sums were wrong, or the contractor changed things, whereas the efficient fans were prone to stalling if overloaded.

I make my scroll housings using Coroplast, in much less time.

This needs an actual rudder so bad. If you lost one or both of those motors in flight, your only option would be trying to yaw with motor fairings, but windmilling those big turbine blades at the same time. With a real tail control surface, you could flip them out of the way and your glide ratio would be less space-shuttle like.
