li-ion battery density: ~2
gasoline density: ~48
electric motor efficiency: ~80%
gasoline motor efficiency: ~25%
energy converted to movement(ev) per weight: 0.8*2 =
1.6/unit weight
energy converted to movement(gas): 0.25*48 =
12
expected range of ev in relation to gas:1.6/12 =
~0.13

actual range of EV in relation to gas ~0.7 to ~1.0

plz help me understand whats happening here. excuse my low IQ
