I don't mind efficiency or loss, but simply can it be transferred? I'm wondering more about the size of the receiver than the transmitter. If the receiver is positioned within the power transfer field just how fast can the power transfer be initiated? I'm assuming the receiver needs to detect and initiate the resonance to initiate the power transfer and it can start very fast in the order of nano seconds.

Your question contains several inconsistancies and things that don't make sense. You apparently want to transfer a sizeable amount of energy wirelessly into a car from some sort of transmitter. You say you want 50 kW energy transfer rate for 2 seconds, which is 100 kJ. Now for the inconsistancies and problems:
Put another way, the intended pickup coil will only be a small part of what the magnetic field produced by the transmitter "sees", so it's characteristics won't have a large effect on overall operation and won't intercept a large fraction of the total power.
