Did anybody else notice the ridge that runs the circumference of the nose on the clay model? Below is a highlighted version of the pic. I am no aerodynamisist, but I think this may have been an attempt to seperate the boundry layer of airflow from the hood and fenders, essentially creating a "hole" for the car to drive in. If this is what it was for, the car could theoretically draft itself. The boundry layer only needs to be seperated about an inch or two to make a difference, and I think it may have been entirely possible on the full scale car with this ridge. What do you think? Any other explanations/theories?
