Never thought I would be see a topic concerning an EV labeled "Hypermiling".
Best tips for range is to travel under 60 mph and pick a route where you have to brake often for regen.

I’ve gotten 72 miles off a charge in a 2013 Volt (round trip)

Lots of things people say aren’t important become important if you want to go as far as possible

Details?
Outside temperature?
Stop/Go traffic?
Could you replicate that 72 miles consistently?

Did GM change the "carwash instructions" to prevent brake lockup?

Travel under 60 mph, yes. Pick a route where you have to brake often, no. Yes, an EV will do much better than an ICEV when you brake often, but there's no way that braking often uses less energy than traveling at a constant speed (assuming equal speeds while driving). I'm sure you lose 10-20% of your kinetic energy even with regen.

My twice on the weekend trip was 65-72 battery miles consistently April - October

Winter even in -20F I could maintain at least 50 miles but I did some tricks to make sure the battery was warm and full before departure

Driving was mostly slow Country roads with town segments at the start end

Once the “recall “ was done and i changed from non-OEMs it tanked quite massively then my route changed so I didn’t have time to wear in the tires to see if it would come back.

I lost a permenent 1kwhr from the battery after the recall

... and pick a route where you have to brake often for regen.

Under that theory, your route would be best if you had to brake so often you drove 0 MPH!

Stand still is best indeed ! 🤣🤣🤣

So why does the OP dare to try it??

On the 2022 and 2023 Bolts, there is no shifter, it is just a button right next to the "pull button" that puts the car in drive. So there is little risk in pressing this button that you will mistakenly select reverse or park.

Also I would not recommend doing this at 45mph or greater, because if the hill is steep and long enough to maintain 45mph you might as well take advantage of the regen to charge your battery.

I think it is only useful only if you have a long gentle slope, a place where gravity can help you maintain speed or accelerate to your desired speed without having the regen interfere. Also if you are coming off of one small hill and you want to carry the speed from the hill a tenth of a mile or so to get up the next hill, neutral gear seems to be useful.

Use google maps and look for the eco leaf showing which route uses the least amount of energy. It will tell you what percentage of energy is needed to travel that route compared to the others.
Then decide if you want to save energy or save time. I drive from a small town 20 miles to a nearby larger town. If I take the interstate emergency route that runs parallel to the interstate it uses 40% less energy than driving on the interstate.
It costs me an extra 5 minutes.

 

[VoltoBolt]

Is "interstate emergency road" just a newfangled term for "frontage" road?

 

[MDVS]

When the interstate is closed this is the route that you are directed to take. It is not within sight of the interstate. It's all country from my town to Kalamazoo.

When I used to drive Uber full time last year, I clearly got better range in stop and go Los Angeles driving than I did from picking up a passengers back and forth at DTLA and LAX and driving them on the Express Lanes/HOV lanes from Interstates 110 and 105!

And when I received my new battery, the extra 50 miles almost completely eliminated my need to DCFC during my 180-250 mile Uber driving day.

Under that theory people have reported getting 300 mile range in the bolt driving in the city

Hmmmm. So lots of stop and go traffic really does extend range. Color me shocked.

Regen is not as effective as staying a steady speed over any distance. There are losses with regen, it is however useful instead of wasting heat at the brakes. But if you were to go say 10 miles at 30 mph non stop vs same distance with any number of stops, you will have more in the battery at the end of the 10 miles if you never stopped. There is no free lunch with regen.

It's more about the lower average speed than the stop-and-go itself. I'd imagine doing a constant 40-45 mph without any slowing or stopping would be even better.

Physics is adamant about making everybody pay for lunch.

Physics is adamant about making everybody pay for lunch.

But with regen, lunch comes with never-ending servings of our famous breadsticks,
garden fresh salad and homemade soup.

It's not the stop and go traffic, it's the slower speeds in between. If you were able to travel that same route with no traffic and no lights, your go even further. If you still made the stops but were able to floor it up to 80mph in between those stops, you'd find your efficiency worse than on the highway. Physics!

The stop/go traffic regens the battery. I thought this was well known?
do you even know what the term "Physics" means? Have you ever taken a physics class?
