Oh, I know the RX-7 is not a particularly good starting point for a hypermiler...the engine alone disqualifies it. What attracted my eye was the aero nose. Compared to what basjoos had to do to his civic to give it that kind of nose, the RX-7 is light years ahead.
The RX-7 has some easy cleanup items that would really help...exposed wipers, huge mirrors sharp cornered front fenders. And that drip rail is probably half his drag right there!
I'm really just musing about shapes. As basjoos has shown, a long sloping nose coming to a smooth point gets the air going in the right direction, and the RX-7 has that feature without having to go to the extremes basjoos had to go to.
It's all good.
