When thinking about the back of the Beetle I was thinking that you might consider the differences between:
*Beetle
*AUDI TT
*Porsche 911
*Porsche 911 GT1 (1996)
When extreme performance is critical the solution is partly found in fineness ratio.
Compare the New Beetle,at L/H=2.56
the Porsche 911 GT1,at L/H=3.991

If the entire back of the Beetle were filled in up to the 'Template',you'd have the potential for Cd 0.314.
At say the old double-nickel speed limit,if you were getting 30 mpg,you'd be looking at 32.6 at factory length.
