Numbers with Hilltop Reserve

A dear friend who also has a Bolt (and reads these forums but has never been able to log back in after signing up originally so he cannot post) told me I should post these pictures from last night of the app once it completed charging and then of the dashboard this morning before leaving for work.


He didn't believe me when I was telling him what the GOM was saying every day even with hilltop reserve set (she's a 2017 so it sets what it wants not what I want) and said that some of you might get a kick out of it too. I'm still not sure if he completely believes me as he said it was impossible and that I would need to have a bigger battery to get those numbers.


I dunno, I just drive her and have never ever cared for math!

I set my charge level to 100% twice this past week. Saw, respectively, 292 and 293 on the GOM . Last night I charged to my normal 75%. Showing 219 on the GOM this morning. Lots of variables with the GOM.

Looking through my photos I found one with 277 miles on the GOM after a charge to hill top.

Was taken last May between seasons where one doesn't need heat or air conditioning.

Keep on Bolting!

Yeah I told him I didn't think it was anything special, just normal for me so far. I'd love to know what yours stated around that time if you had let it charge to full! That's awesome.

260-300 miles seems perfectly possible if you keep it below 50mph. What is your average speed?? I'm lucky to see 190 miles with hilltop on my 2018 as I do ~68mph (110kmh) on rolling hills for the majority of my driving.

If you are lucky enough to have 60 kWh of usable battery capacity, and you charge to "hilltop", which typically ends at 88%-90% SOC, then you have ~53-54 kWh. Off the interstate, in mild weather, you can easily see 5 miles/kWh. I have seen as high as 5.9 miles/kWh.

I charge to 70 percent (I have a 2019) and I usually get 220 on the GOM.

This is in 80 to 90F weather with air conditioning manually controlled, and car preconditioned in an insulated garage. Most of my 38 mile round trip commute is under 55, with 20 percent at 60 miles per hour.

During our 'winter' (~40F) it will probably drop down to about 200 miles at 70 percent charged, based on my experiences with my last car, a Chevy Volt.

Weird number.

Happily driving The Gonk 70 (Shock Yellow 2019 Bolt)

Your summer GOM reading amounts to about 5.2 miles/kWh...totally doable. Your expectations for winter driving equates to 4.8 miles/kWh. Your Volt had an ICE engine providing free heat. Unless you live somewhere like California, or the deep south, you will not be seeing those numbers. Even if you only drive in the city, and are willing to use only steering wheel/seat heat, I don't see how you will manage it.

Never mind, I see you live in Texas.

I've only charged it to full maybe three or four times since new. Took one picture right before taking it in to get the propulsion module recall done. The GOM was 290 with a full charge but was taken in November where I'd probably used a little bit of heat by then. My lifetime average was 4.6 mi/kWh at 10,051 last year when I took that picture. Over the next 5,000 miles, my average is 5.0 mi/kWh.

Sunny, warm Florida, Winter months, my Max GOM routinely states 305 miles.
Nothing magical, just batteries love warm weather...
