Dave Cloud sent some pictures of the chassis and battery packs, during construction:
And a "reminder" of the (more) finished car:
And the descriptive part of the email:

I am installing batteries Monday & Tuesday.
The 80 mile run we did a couple weeks ago was without the plexi-glass boat tail.
I'm still only 60% done with the body, so don't be surprised if the watt hours go down in future runs.
Thanks for your kind words and posting on Ecomodder.
There was some mention there of potential problems of turning with dual motors. My motors are in parallel, not series, so demand is set by the controller not by the RPM of the wheels. There are no problems steering in corners.
The back wheels are 38" apart (outside to outside) for aerodynamic reasons. As a side benefit, however, when driving straight under heavy load, I can take my hands off the steering wheel, turn off one motor, and the car stills drives straight.
