sc1 aero mods

Smooth wheels helps a lot, especially on the front since the wheels are not (easily) covered like the rears. My Scion xA has larger than normal wheel openings, but doing this sort of skirt might also help on other cars:

Antenna is a home made (and designed, on NEC) 2 meter, 3 element x 2 broadside beam, > 10 dBd gain at 5 feet above the car. (rubber neck attractor) I will be painted black and used primarily in the dark.

Neil, That looks good, I was thinking of something like that but haven't worked out how to fill the gap behind the tire without it catching the air. I have screwed in 1 1/2 inch black poly tubing around the opening which I formed into an arc in the oven using a bicycle rim. (pictures later). My current thoughts would extend the fixed part over the whole wheel well with circular slots cut 2/3 around and something elastic for tension, but maybe the top hinge is the way to go. I think that the Bonneville wheel covers won't attach to the aluminum wheels.

I was trying to mimic the original Insight -- fix what you can, I say.

You can use foil tape to cover allow wheels, to make them smoother. Blocking the holes is key.

Thanks for the antenna info. That's an Arcosine-1.0, ha ha.

That's been my problem for years. I finally solved it here :

However, that thread is out of date. I have since simplified the parts and moved to alimuinum wheel covers. This pan has a slight gap, maybe < 1/2" :



I will publish a new thread with all the details.

"The GM Aero 2000, one of the most aerodynamic automobiles ever developed, was unveiled in 1982 at the Epcot Center World of Design display. The experimental four-seater featured sliding doors, front wheel skirts top-hinged for access to wheels and tires, and a speed-regulated rear foil to reduce fuel-costly air turbulence. Many of the design concepts are evident in GM's electric car, EV1."

The hub caps look like pie plates to me...top hinged it is...

It has a 3 cylinder TDI engine...


The difference between style and aerodynamics is aerodynamics never go out of style, cool a pop out boat tail...

This one has a longer tail:

I'd buy an SC1 and re-body it into that.

TOWMBO however, would disagree.

I put a front wheel skirt on one side and It hasn't blown off yet:


Poly tubing ready for baking at 220 for 15 minutes:


Poly tube formed attachment screwed into inner fender:


Wheel skirt mounted on fender:


I used 4 cable ties on top around the poly tube and a bungie cord on both lower corners to pull it in. I can hear it rubbing the tire sometimes. I think a spacer pushing at the wheel center would help.

A picture of the whole car with the front wheel skirt would be great!

Maybe this afternoon I can get a picture with road grit streamlines.
