There seems to be a fair amount of variance on gas mpg- thought this might be interesting.

I usually get low to mid 40's but I tend to drive at the speed limit or even slightly below, depending on the length of my highway trip.

Best,
Rick

Haven't used gas in my '17, but in my '15 I average 42 on the highway driving within 5 of the speed limit, but the highest speed limit near me is 70.

Ditto.

Last year's road trip of 8500+ miles, all in CS mode, I averaged 41.5 mpg. This year's road trip of 9890 miles, all in CS mode, yielded 42.6 mpg. I kept my speed at 65 mph or at the speed limit, whichever was lower. The Gen1 Volt is a terrific road car!

Per my voltstats, i get 38.1 mpg (cs) for ~ 5100 gas miles with ~14000 EV mies (total 19100 miles).

I usually dont use gas for my 60 mile rt commute but i do use it about once a month where I make a 400 mile rt to vist my dad.

When i make these monthly, long trips, i typically drive around 65 -70 mph with 90% being on freeways. Volt stats link is in my signature. Hope this helps.

On the long trips where I've either been in HOLD mode, or have run out of battery and gone over to the REX, my Gen 1 has been pretty steady between 38 and 41 depending on terrain and conditions of course.

The worst I've had was driving in snow/slush and powerful winds where it was down to about 34ish but seriously I shouldn't even have been out in that muck.

It is interesting to make a comparison to the Gen 2 vehicles.

If I drive near or at speed limit and I don't use climate (e.g. fan only), I normally get about 43mpg on the open highway. Lowest I have gotten is 38 with AC blasting doing about 10 miles over posted speed.

Our 2016 Volt LTZ has been averaging 45+ mpg just on regular 87 octane gas from our local Costco. We purchased our volt during the summer so we have not been driving it on gas much this time of year with temps high 40's to 50's, with frequent rain and wet roads. I expect with winter conditions 40-45 mpg but have not had a chance as the weather really changed here not too long ago. I know our 2010 Prius had gone from high 50's mpg to high 40's to low 50's mpg during the recent weather change. Also winter blended gasoline also drop's your gas mpg as well. I have noticed that in comparison our 2016 Volt obtains significant better mpg's than our 2014 Volt did.

2017 LT. 38.8mpg over 3000 miles on hold. Speed between 75 and 80 most of the time, some stop and traffic due to road construction. Lower speeds use much less fuel. One day I was stuck behind a 40 mph truck on a rural two-lane for 25 miles and was getting around 55mpg on hold

I put 40-45, but mine is right around 40. Usually I don't have to run gas for very long so it runs rich to warm up and then I don't run it for much longer.

I usually get around 46, unless I'm going 80+ MPH on the highway, which doesn't happen too often in Chicago. I tend to accelerate and drive pretty quickly, too.

I get just over 50 MPG and voted as such. The voting shows no one has gotten that. Where's my vote?

This summer with our 2016 Volt driving down the Oregon coast on Highway 101 to go fishing we averaged 54 mpg just on gas and nearly 68 miles on electric for our 135 mile round trip. Now with temps in the upper 40's to mid 50's or so and rain, wet roads, mpg on gas the last trip, yesterday, to Portland Oregon via Highway 26 returned 51 miles on electric and 45.6 mpg just on gas, gas miles 117. Light to moderate rain and temps in the low to mid 50's and from sea level a total of 6 mountain passes, 3 each way, up to 1642 feet elevation. In comparison our 2010 Prius would have averaged, under the same conditions, 48-50 mpg.

Maybe we just lucked out with a more efficient engine than normal, if not it appears GM did their homework on improving the efficiency of the 2016-17 Volt's gas motor.

You will need to check with H. Chad.

My assumption is they do not want to mix Gen 1 results in with this poll as it was posted in the Gen 2 forum. It looks like some Gen 1 owners may have already voted therefore requiring a do over with clear language of who they want to vote (if so this would be the greatest case of voter fraud in the USA). (As a side note my 2013 just traveled 600+ miles over the weekend at close to 80 MPH most of the way with avg of 36 MPG)
