When To Use Chevy Volt's Hold and Mountain Modes for Best MPG

You are a new Chevy Volt owner and decide to take an out of the town trip and wonder how to use the Hold and Mountain modes of your Volt to get the most miles per gallon. Here are several imputes from current Volt owners who share their experience in Chevy Volt Owners public group on Facebook.

2013 Chevy Volts brought few welcome changes adding an EV Hold Mode to the existing Normal, Sport, and Mountain modes. Both EV Hold and Mountain modes are similar, the difference is that the Mountain Mode will hold the battery at 45 percent state of charge, while EV Hold mode will hold the charge in your Volt's battery as soon as it’s switched on. Here some Chevy Volt owners share their experiences on how to use the Hold and Mountain modes for the best MPG.

Ways to use EV Hold Mode

Eric Douglas
Hold mode is good for freeway, it uses gas and keeps the battery where you left it (I'm told that you'll get better mileage when the battery is more full, but I'm not certain).

Betsee Thompson
I'm in Michigan with a new-to-us used Volt. What I've found works best - and I've driven our Volt to Wisconsin, Massachusetts, and Toronto on our longest trips - is I use the Hold mode for on the highway or any long stretches of certain miles per hour. That seems to get me the best MPG. I prefer to save the electric for in-town driving or stop-and-go on the highway stuff.

Paul Brook
At high speeds use hold and round town/stop start use EV. But above all else: don't obsess and don't be afraid to use the engine (like some obsessive members). 70 miles is nothing for the Volt. Just make sure you don't come back with any battery remaining.

Phil Chang
My commute is about 75 miles. I use Hold mode on the freeway, but switch to Normal mode in traffic jams. I average about 95-120 mpg. On a really bad day I hit 150 mpg round trip.

Timothy Peters
My commute is about 75 miles. I always use hold on the freeway and use the electric modes on side streets. It works well. I am not as concerned about efficiency as much as saving the quiet experience for the lower speeds, and using the gas engine when I can't hear it on the highway.

How To Use Mountain Mode

Eric Douglas
Mountain mode, if I understand correctly, will use battery, and give you an extra push - which depletes your battery faster than normal. So I'd use that sparingly.

John McVicker
Leave home in Mountain mode. Will switch to engine on the highway - and then with 16 miles to go, back to Normal mode. I do this all the time.

Chad Wehrling
Mountain Mode is used for hilly travel. Keeps a 'reserve' in the battery to get you up those hills. Does not give the car any kind of "boost" in power/torque.

I drive a late (September) 2013 that has HOLD mode. I use HOLD a lot. Be careful though, If the battery is kept above 50% you run the risk of overcharging it while going down hills. Mountain mode is used to be sure the battery has 17 to 20 miles before you drive up a mountain. The GENERATOR by itself cannot add enough charge to the battery on long uphill grades on mountain roads. The battery will naturally decrease charge while driving uphill. The battery may go below 5 miles while going up long steep roads even with the generator running. As soon as you get to a flat area Mountain Mode charges the battery up to 17 to 20 miles again. The engine will stop at that point and when you go down a long hill regen can charge the battery to 33 to 45 miles or more. Mountain mode (MM) stays off until you reach 17 battery miles then turns the generator back on. The range meter can read over 50 miles downhill on regen but none of this counts on your car electricity calculator. Hold mode works the same way. It only charges to the point where you turn it on. It can hold the charge at 33 miles or at 5 miles forever but will increase or decrease according to the road grade. Now for the facts... If the battery is depleted and you turn MM on - the car will get about 20 mpg for 20 minutes on a flat 65 mph road or zero while parked (charging is like it is plugged into a 440 fast charger). You get faster charging (15 minutes) while parked but no driving progress. After that, continuing MM on a long trip will get about 39 mpg on flat roads. Hold mode will get the same mpg results on a long trip. AC will decrease mpg by one mpg, or 38 mpg. Around town is always at a lower mpg. Hot weather, with AC, on 2000 mile trips, with gas only - gets me 38 mpg. Cold weather 1500 miles (32 degrees and electric heater) got me 28 mpg. Note that I never charge the car on long trips. I use gasoline and MM only to keep the battery at about 17 miles. In cold weather it may only read 10 miles. I use HOLD when I don't want to engage MM. Hold is best on long flat road trips of 200-300 miles. One other benefit in hot weather of the VOLT and MM, If you pull into a rest stop with 17 miles of electricity and it is HOT outside you can crack a window, turn the engine off and run the air conditioner for three or more hours if you want to take a nap. KOOL!!!
I am going to travel 2400 miles Az to Ny. What is the most efficient way in 2011 volt?
