From the UX presentation from CES it looks like that there may be three options for the Harvester. Pure EV, Max, and Auto. I hope they allow us to set when the Harvester kicks on.It'd be nice to be able to start the RE shortly after getting on the road when I know I'll be going a long distance without reliable charging. That way the RE has as much time as possible to top off the battery, rather than waiting for the battery charge level to deplete and then needing more power out of the RE
As long as the air intake is up high…I'm curious how the engine "tucked low, out back" is gonna work out with their claimed 3 foot fording capability.
