thinking  The Fisker Karma is rated as  52 MPGe or stated as 65
kWh/100 mile for upto 32 miles on Electric Power. This is using
the Combined EPA cycle calculation that is a combination of 5
EPA cycles.  After 32 miles on electric power, it becomes 20 MPG
on the same combined cycle.  Putting an artifical label like 100
miles at a time is dangerous. Everyone drives different
distances.  The Karma is capable of 32 miles of Electric Range
between charges. The overall efficieny will be significant
different at 25, 50, 75, or 100 miles between charges. The EPA
is not attempting to project this number.  At one point in time
the EPA was considering doing such a thing. By using data
gathered in 2001, SAE created a curve that projected the average
electric utilization rate of a car given its AER. The SAE then
recommended to report the ga
