They have newer information on the energy consumption: it is just 6.2kWh/100km which is almost exactly 100Wh/mile (just under), driving at 8090kph (50-55mph). This is even better when you know they used a brushed DC motor (21kW) from a Vectrix (sp?) which is not as efficient as an AC induction motor or a brushless permanent magnet motor; and it does not have regenerative braking.
