Sorry if wrong place BUT... I have a question. As most new Volt drivers are... I'm becoming obsessed with the best mileage. I will be about 75/25 electric/"fuel" miles. What is the optimal speed to "drive gas"? I'm sure highway is probably the most efficient time to use hold correct? Is there an optimal speed? 60, 65, 97, 70? I'm sure flat vs hills, slow grades vs steep all make a difference I'm just currious. Btw I've got about 70miles on gas and I'm at 40.2 :) around 215ish overall mpg with somewhere around 350 miles +-20.

Loving it btw :)

Ah. That's a somewhat different question. The general consensus is to use the ICE for part of the freeway portion. It's likely a little better for efficiency without the start/stop cycles of the lower speed parts, but mostly it's a lot more pleasant - at 60 you'll only know the engine is on from the instruments, but in stop and go you'll feel and hear the engine.
I totally concur with Walter's logic. It's the exact logic I utilize.
