It's been 2 1/2 months since I picked up my new Volt. During that time I've seen a slight uptick in the battery range. It started off somewhere in the 58 mile range but yesterday started out at 63. Anyone else observe this? Is there a break in time for the battery where it starts to hold a charge longer? Not complaining and love to see it go higher before the weather turns cold (currently sitting at 240 total MPG...woo hoo!)

Good for you.
It all depends on your driving style as to what shows on the "Guess-O-Meter". Currently I am getting about ~ 235 Mpg, 1L/100 km, but know I can do better. Then it sometimes says 2.8 L/100 km so it really depends on style and other factors like temperature, hills and my heavy foot! LoL

Keeping it below 70 MPH really helps this. Above 70 the Volt's efficiency nose dives.

Most of my driving is short distance which is perfect for the Volt. In the time I've owned it I have yet to put gas in it.

If you want the GOM (Guess-O-Meter) to read as high as possible,,,,

Drive as slow as possible.


You'll be saving Nickels per week that way!:p

This isn't the battery breaking in; what you're seeing is the car learning how you're driving.

Unlike Tesla's "rated miles" display, the EV range on GM electrics like the Volt is based on your driving history with the car - it uses fancy Fourier transform math to strike a balance between the fixed Wh per mile Tesla uses and the instant forecast of Nissan's guess o meter (which will jump by 30% in a minute or two based on changes in driving style, at least on early Leafs.)

Summer temps and road conditions give you the best electric range as well as gas only mpg (C.S.). Our 2016 Volt Premier with nearly 45,000 miles has been averaging 65+ miles per electric charge. The last few trips via Highway 101, Oregon Coast Highway, have been over 70 miles per charge with highway speeds of 25-60 mph. KWH used for those miles have been 14+ with the highest 14.6 KWH used.

Winter brings the electric range down to about 45 miles with temps in the high 30's to low 40's F. along with heavy rain and standing water on the roadways. Our 2010 Prius also drops way down in mpg going from 52-55 mpg in summer (calculated not dash readout) to 43-47 mpg in winter under the same conditions.

Ah, this makes a lot of sense and I think I better understand what Manitoba Keith was saying.

It'll be a bummer to see the range drop but I fully expected it to do so. Thankfully, even with the reduction, my day to day driving will easily fall within the reduced range. My concern will be precondition (though I will do that while plugged in to my level 2 charger)

Don't believe those other posts. My 2011 Volt is rated 35 miles on battery. After 7 years, the battery has grown to 200 miles on a charge. :)

Not there yet but often when I leave home the display shows fully charged 67 Km. and when I get into town (a 8-9 Km. trip) it often shows 66 Km to 68 Km. range. Goes down after that unfortunately.

Tire break-in also helps increase range. I saw some improvements over the first 1000 miles.

2013 volt here. My GOM has never gone over 41miles, has spent most of the time in 37-39 mile range (which has been pretty accurate) and gets mad at me about mountain driving and drops to abut 32 for a day or so after I've done a bunch of mountain driving LOL.

I keep wondering what the deal is. I have one 2013 that can never get over 41 on the GOM and like you the range is 37-39 max. The other 2013 the GOM goes to 49 and range is anywhere from 44 to 47.

My 2013 has been reading 42 miles every morning, but in the last week or two it has been increasing. Now it says 45 miles. I also notice that while I used to show 9.7 kWh used at the end of the charge, now it shows 10.2 or 10.3. Prior to this mileage increase I did let the battery run all the way down before recharging, something I don't do very often.

All of this driving is with A/C running, set to ECO and 72 or 73 degrees.

Part of the increase is the car learning what the driver is doing and the rest of it is the driver learning how to more efficiently drive an EV for best mileage

You seem to be saying that after you drove your new 2011 Volt off the lot, with its 35 ev miles per charge window sticker rating, it was all "downhill" from there.

And now, because of the excellent mileage that comes from driving in that direction, the GOM is offering you a 200+ mile range estimate per charge (or at least, that’s what it would be if it were not for that max limit GM placed on the Gen 1 Volt ev range estimate).

That's the tires breaking in. New tires gain rolling efficiency over the first thousand miles or so as rough spots left by the molds are worn smooth.

I know my avg range reading on 2012 volt got reset at least once to about 35-36 range.
That was the the 2011-2012 upgrade to 360 volt battery support and the cooling radiator float switch install.

No idea if any software flashing or 12 volt battey replacing will set range back to default ?

Or what is the default for the different Volts ?
