I have been wanting to know this as well. With both the roadster and the truck, the battery seems to be quite a bit more advanced than what we have seen previously. The car is smaller than a model 3 but has a battery that is more than twice the capacity of what they said was possible before. It will be fascinating to find out what is actually behind these vehicles. On a pure specs basis, it sounds incredible.
