IMHO, AC Propulsion (Tesla Motors) uses AC because a mechanically commutated DC motor that meets the high turn down ratio of a vehicle application is more complex than an electronically commutated AC motor.
Two coil or double-resonant circuits - Virtually all present Tesla coils use the two coil resonant transformer, consisting of a primary winding to which current pulses are applied, and a secondary winding that produces the high voltage, invented by Tesla in 1891. The term Tesla coil normally refers to these circuits.
