So i have looked and not seen any 1 talk of mountain mode this way but i found a way to do it

So i live in FL and its not ..to.. hard for me to get 55EV rage from my 2014 chevy volt

most of the time i see all ways 51 miles but as its been getting colder here in the last few weeks i find my self a few miles low of making it home and after playing with it some i found a way to do it

car
2014 20K miles on it stock tires my vin was under the 6XXXX so i have the stander battery for that year :mad:
all AC and heat off and why driving in L
8 miles or less range left when starting to self charge
speeds never over 30 mpr but 20 seems to be it so this is used in towns and school zones or stop and go or at many red lights just blocks apart
the more stops and regen the better and in doing so i can push 10 miles of range into the battery in a few miles of driving
when stopped the ICE well stay running but as soon as the ICE tuners off at a full stop say at a red light the battery is as full as it well get and move back into stander mode . i see this from 18 to 21 miles on my cluster
keep in mind why in mountain mode you well not see all miles made to you intell you come out of it so some times it well show me 17 miles but as soon as i go to EV mode it well jump to 20 miles and so on

mountain mode is still just a hold mode so all regen helps push the bettery voltage up faster and the ICE covers all starts so its a ++
RMP stays low on the ICE at the min.. but as soon as you see power move from 1 ev motor to the next your going to hard or fast .. you see this on the cluster on the KW meter as power moves from 1 side to the next as IF the trans is moving gears so if you see this slow down and late the system move back

when doing this is at a time we all would think not to use it as we want EV mode only for towns and slow speeds but if you find your self needing a few miles to get home try this 1 time

i have tested this 2 times and used 1 gallon each time to see 38 miles and 40 miles
this is to really only add 10 miles each time so if you want to test to a full gallon it well take a good trip in town to do so but 0.50 gas used should show 18 miles or so ..

not the cluster but the center screen that says MPG
i am not sure if all cars do this but my car shows all miles made and used buy the ICE as gas used
remember to keep in mind when testing this for your self to add miles driven and miles made
if you are not sure if its showing miles made add a few miles this way and go to EV mode .. if its still adding miles to the gas side as IF your in gas mode its adding it up for you
as soon as all miles made are used it well start adding EV miles again on the same screen

i would love to see if this helps any 1 else and what numbers your getting
and sorry i am a old school guy and dont like to see my ICE start and stop so much
i like to make the motor run when i want it to and stay running as i need it

Just another popup of that V word that we are not allowed to mention around here...

Hard to see your point in all of that and I agree with calebh2002 another version of the V word.

38 MPG is not hard to believe especially at the speeds you are talking about for such a shore distance. My lifetime average on the Volt is around 37 MPG and have 60k miles on it.

When I drive for Uber, I will average 150ish miles in a day, of city stop/go driving. I do not attempt to Mountain Mode / V-word my car, and I consistently see 38-40mpg in normal CS mode.

In the past I have used MM to charge/keep charge, should a rider ask me about the car, so I can demonstrate. The times that I have done this have resulted in much lower MPG for the day... in the lower 30s.

Just like the V-word process, it *is* possible that your unique situation could result in an extra MPG or two, but is it worth all of the extra effort of mashing the button and monitoring the GOM? In my opinion, not so much.

Ultimately, for everyone reading this, its your Volt, your dinojuice in the tank, use it and drive it as you wish.

I'm studying the VoltStats MPGcs of some of the people that attained very high numbers. Some of them were strategically using Mountain Mode, based on the 15-day moving average pattern of their chart as compared to my own experimentation of the Mountain Mode.

As for me, I don't know how to game the Mountain Mode driving technique on a flat terrain that would boost my MPGcs number, it has ended up lowering my average MPGcs so I am only using Mountain Mode when I really have to, that is, when I plan to climb a mountain a long way before.

I had an obsession with VoltStats the first 6 months I owned mine. I haven't looked at my car's stats since.

What is this V-word that you're all talking about, VoltStats?
LOL, at least I'm assuming you don't mean v-g-g?
It's like 'revolting', only the first time. The subject a long and acrimonious thread on the topic of gaming MM to improve mileage. As I remember every thread on this topic ended locked. Something like Monty Python's Killer Joke.

Volting is the "v" word.

And, I had a real hard time reading all the sentence fragments and lack of punctuation in the OP's post.

The OP’s technique is not new:

Switch from Normal to Mountain Mode when ev range is just above 0. MM will recharge the Gen 1 battery to ~4 bars in 15-20 minutes using ~0.4 gallons or less of gas in addition to the gas used to move the car down the road while this is happening.

Switch back to Normal and drive using the MM-recharged battery. Distances will count as gas miles when using this power. If you now drive @ 20-25 mph, you may be able to drive further on this recharged power than you could at normal speeds using the ICE and the same ~0.4 gallons of gas. Driving further on the same amount of gas = higher MPGcs.

Claims of improved gas mileage based on small amounts of gas consumption should be taken with a grain of salt. This won’t work with 2011/2012 Volts - they have a glitch that counts the MM-recharged power miles as electric miles, which lowers the MPGcs. Much harder, too, with a Gen 2 Volt - the MM buffer is only ~2 bars of power, i.e., gas mileage improvements would be based on MM-generated battery miles created by using less than a quart of gas. Any additional gas distance improvements obtained from regen have nothing to do with the use of MM.

Thanks all for bringing up the V-word, especially since I'm sure it brought back a lot of painful memories!
And thanks @wordptom for the crystal clear summary.

You can try to game the modes, but it is a lot easier to just drive in normal mode. No one has been able to convincingly document any significant gains from gaming the modes. I will concede that maybe you can squeeze out a slight edge under perfect conditions, but is it worth the distraction from your more important job of driving safely?

??? some thing way over my head here .. i am new to the V-word so not sure what its really for

yes i know with my car running at 67mpr on along flat road i see 41 MPG and this was not about that at all

this was about gaming the MM mode to get it to self charge the car and still keeping the 40 MPG as we all know trying it why at high speed kills MPG

thanks for the link some 1 added . it was hard to find as i did not see it when looking to see if any 1 else talked about it

My 2015 now has a lifetime of 109 mpg
I use normal everyday mode all the time, the only time I use hold mode is when I travel over to Tampa, 120 miles away
I use hold mode strictly on the hiway, and hiway miles I average 47 OMG all the time
I now have 14,670 miles total, which all miles except 10,750 are ev miles
And 4,700 miles are gasoline.
I love my volt
