Interesting but my thoughts have been to make the trailer an EV pushing our Prius for urban commuting:
  • lower peak power - urban travel speeds require lower power reducing the thrust requirement.
The same logic works for existing ICE vehicles. Other than parking, an urban EV pusher makes a lot of sense. If close coupled, the parking problem is reduced.
