There we go. Reducing your rotating mass in teh drive train radically increases mpg because you lose in the objects weight and the energy needed to keep it spinning.

This is also one of the big reasons that Motor-In-Wheel designs are heavily considered. It increases the unsprung weight but it reduces the number of components of your car that need to be kept rotating and several thousand rpms to keep the car going.
