Empty weight: 2,620 pounds <-- That is a light aluminum car with a battery big enough for a 375 mile AER trip!

Battery Detail: Li-Fe-Poly (260 Ah/380 V) cell voltage of 3.8 volts <-- 100 kWh pack?
#
Battery weight: 660 pounds <-- More than likely 120 kWh at a .2 kWh/mile minimum from just 660 pounds? Yet another game changing "Super Battery" Spec.
