The E-Type is not as aerodynamically clean as its shape suggests. While the basic shape is reasonably efficient, items such as drip rails, bumpers and overriders, and that big hole in the front all conspire to increase the drag coefficient. I believe that FHC 9600HP was not able to reach the magic 150 MPH until they removed the front overriders. I also once read that someone with access to a wind tunnel tested a model of a FHC and found that the CD was actually lower when the model was tested in reverse. Putting all of this into perspective, the E-Type is still more aerodynamic that any of its contemporaries.

Planning on getting E-Type No. 3 as soon as possible....
