A small car with a badly-tuned (for FE) four cylinder getting 20-something mpg is not hard to imagine. But looking at the MX-3 in real life and in pictures, it looks like it should have a drag coefficient much lower than 0.32.
I'd like to tuft-test one. If flow remains attached across the back of the car, I'd buy one and promptly put the engine on eBay.
How does it compare to the streamlining template?
