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

My scenario was I was about 5 miles short of EV and I couldn't decide if it would be better to use the gas on the highway and EV on the backroads.

Your manual may have had this information:

Electric range is maximized at 80 km/h (50 mph) and below. Higher speeds use more energy and can significantly reduce electric range.

So above 50 mph is the better time for using hold mode.

I also wondered if using mountain mode was a good idea when I was out of EV, for say 10 miles on the highway or backroads, to build up slightly for the last couple miles from the off ramp to my house.

It's a waste of gas if you're using hold mode anyway, and certainly not efficient. I've done it a few times it though when my battery was drained already.
