Time over & under 40 mph?

[todayican]

I understand, there needs to be power to accellerate and climb hills.

On a highway however the power demand hovers around x HP, my plan, and others can do what they see as best, is to optimize a 1 speed diesel to cover cruise needs and electric to accellerate from a start and cover increased cruise needs (like going up hills)

as well as use regen more as a "gen" to recapture diesel hp back into the pack.
