Interesting. I don't suppose you've driven in the mountains have you? If so, describe to me what the engine and HSD would be doing on a trip down I-70 from Genesee to Denver at 60mph. Would the ICE be running and using a small amount of gas or none? How easy is it going downhill to swtich from ICE to HSD? How much regen do you pick up? Does engine braking/regen slow you down? What if the SoC is full?

How about the trip up I-70 (average mpg going UP at ~55-60mph)?

.

Commuter car, grocery getter, and summer road tripper--average 10k miles per year.


Winter road trips and ski trips, bad weather commuter and my wife's "daily" driver--expected average 4k miles per year.
