don't forget that the power available to the Tesla motors decreases as the battery is used up. Seems odd, but as usable stored power decreases you are not able to pull as much from the battery anymore.

then there is that whole bugaboo of battery weight.

Is this different in the Siemens engine though? Is that why they say "delivers a continuous output of about 260 kilowatts" emphasis added. I guess all that means is that they're really able to deliver more power than advertised on a full charge?
