I looked at the math for converting a small pickup a few years ago. What made it practical for me was my short commute of 10-12miles a day and the fact that we get lots of sun in the southwest.

On an efficiency standpoint the typical series wound motor gets 60-70% efficiency. A permanent magnet brushless motor gets 80-90% but at $25k+ for a 75hp they are relatively cost prohibitive.

Edit: Just looked at the warp 11 motor specs, looks like it peaks at 91% and is a series wound, so my above statement is wrong.
