It uses 3 motors (2 in the back) and has a 200 kWh battery pack. The reason for such a large battery is so that they can draw more total current without overheating, theoretically twice as much as the Model S P100DL which only has two motors (1 in the back). Having more motors means you are spreading out the current/heat. The 600+ mile range is mostly a side effect of this engineering approach to performance.
