A 20hp Honda or Kohler V-twin engine chained directly to the wheels would work. The problem I find with such a system are the emissions. The Leaf is considered a zero emissions car (although we know that isn't true.) So it would make sense to me to put on an engine that gets at least ok emissions. Maybe a propane engine with water injection and a catalytic converter would do the trick??

It would be a major headache to implement - maybe do it up similar to how ZipCar does their subscription service? - but a range extending pusher trailer for things like Leafs that could be shared around among the local Leaf community would be smart. That would put the investment to work better.
I don't have an answer for the emissions statements except to recommend the best engine you could possibly install along with the simplest possible drivetrain to minimize losses - chain direct to the drive wheel, I guess. And shape the trailer for whatever aero advantage it could provide.
