Does anyone here know offhand how the EPA determines the energy efficiency numbers for EV's. Is it an extrapolation based soely on the capacity spec that the Manufacturer states? Or do they actually charge the car to ful, drive the test loop, and measure the power as they charge to full again?

It seems unlikely to me that the Spark EV would beat the Leaf by 8% on the highway as the EPA specs show. Manufacturers are famous for figuring out how to cheat the test.
