Cd 0.39 vs Cd 0.19
I got a blueprint of the New Beetle off the web,enlarged it,and put under the 'Template'.
The Beetle is of 32% 'Template' aft-body.
Other cars which share the New Beetle's aft-body percentage are:
* Prius-II ----------------------- Cd 0.26
* Insight-I---------------------- Cd 0.25
* M-B Boxfish------------------- Cd 0.19
----------------------------------------------------------------------------
Certainly,there are more criteria to define the aerodynamic performance of a car's body than it's aft-body architecture.
Curiously,the Boxfish,which demonstrates the lowest drag of the 4-cars considered,just so happens to fit the 'Template' curve perfectly.
