Let me save you all some needless debate........the 100mpg claim on this car is BS.
I've spent plenty of time talking about this car with members of a few Mustang forums, and we all came to pretty much the same conclusion: the guy is full of it. It's just a publicity stunt to get some press for his business....nothing more. Only way he's making the numbers he claims is if he's packing a Mr Fusion onboard somewhere.
