I don't get your question. But that is a roadster, not an S or later. But it presumably doesn't mention intermediate capacitors because they don't use them.
I think you and mikepurvis are both saying the same thing - that Tesla and other electric cars are using batteries only, not capacitors.
I will note that the homebuilt electric cars generally had much smaller battery packs, which could not supply the same peak currents that a 50+kWh battery would have.
