With high speed Bonneville cars, drag coefficient*frontal area dictate the horsepower required to get to a certain speed. Air friction is the enemy.
I think I saw a picture of the blow fish in a wind tunnel, a lot of aero work has been done. They said they were going to get a cd of .20, which is not possible with a car that has its shape.
Regardless, the car, as well as the others from Rad Rides are truly great.

You are exactly right about Bonneville. Many of the car will experience wheel spin, when the drag of the car > than the traction of the rear wheels. Knowing this, when we built our car, we boxed the frame rails and filled them with an iron filled two componant epoxy (Used to make metal forming tools in the aerospace industry) Neat stuff, you could mix several hundred pounds at a time. The curing agent was so slow that it literally could take a week to set up, depending on the thickness and ambiant temp.
Anyway, we filled the frame rails up with this stuff and added several hundred pounds to the car, and it was as low in the car as as it could be. It helped the handeling quite a bit. The car, while looking lightweight was really pretty heavy and solid.
