I'm guessing that the 0.21 is from the flat black Model 3 I showed, with it's flush wheels, etc. I doubt the turbine wheels allow a Cd that low.

George Hurst invented the Jaws of Life for use on racecar tracks and chose as the delivery vehicle the AMC Gremlin:

Dr. A. Morelli would approve. By the time bureaucrats were done with it, the delivery vehicle had grown to a 1 ton truck.

I have seen that car at Bonneville and El Mirage. I think maybe the front wheel well skirts are new too. Awesome vehicle.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

I'd love to visit the Lane Museum. The Petersen in LA is closer to my location, but not as cool.

The auto engineering marvels at the Lane Motor Museum are ridiculously cool | Ars Technica

I won't hotlink the first picture because its huge, but it is a reverse tricycle belly tanker built by Kenny Howard that I'd never seen before.

Why The Lane Motor Museum Is My New Favorite Auto Museum

What I came here to post is the X-51. It's interesting to me because I saw those taillights reflected in the wet streets of McMinnville, OR in 1959.


http://www.hotrod.com/cars/featured/hrdp-0801-top-100-hot-rods/#photo-10

So how has it aged? Let's see:
  • Reduced frontal area.
  • Fins to separate the flow over the top and sides with air scoops at the root.
  • A rolled pan with a dummy grille that today would be an underslung wing/diffuser.

It's still the only car I care for in red.

An idea on how the active Aero Brakes may have ben set up. Probably more complex than my sketch. As more brake force is applied, more G-Force is exerted on the counter weight, in turn lifting the spoiler higher, increasing down force and Cd to show the rig by friction brake and drag...
---
This idea could be applied with a side to side mechanism as well .. So that extra down force is developed when needed...in yaw more down force on one side (like at Bonneville) to counter the high speed wiggles.. or in road course driving..

If you move your post to an appropriate thread, I will move this comment.

I have no idea what the forces involved are, but for an example, lets use a 120lb weight that moves 1 inch. There will be losses via leverage from some angles in the linkage, but you only have 10ft-lb to work with.

The force required to raise the air brake will grow with air speed.

Italdesign proposal. Probably has terrible aero but it sure looks cool. Said to be the inspiration for the VW Scirocco.
