Bolt Range

Mon Jul 25, 2016 1:22 am

Talked to someone that sat in the Bolt at EV Roadmap. Range remaining showed 234 miles, but GM staff blocked the attempted photo :) .

Lots of things can cause a range estimate higher than the official EPA estimate, but makes me think they'll be well above the 200 mark. We should start a pool for fun. Reply with your EPA range guess and I'll add it to the list

EastOcean, 210

My guess is based on the EPA range of 84 miles on a 24-Kw Leaf battery, just scaled up.. BTW, my Leaf will sometimes show a range of 102 fully charged, which goes down rapidly when driving. THe Guess-O-Meter has some algorithm that uses long-term averages, and seemingly most recent trips.

I'm with EastOcean on this

My Guess on the EPA rated range = 210 miles, wq2345

Because the body on the Chevy Bolt includes aluminum magnesium and carbon fiber to make for lighter materials I'm pretty optimistic on the long range and efficiency of the vehicle

If I scale my my Fit EV (20 kWh, 82 EPA) it would be 246
Scaling up the i3 would yield 258 (or 225 if you use 21.6 pack size instead of 18.8 usable)
Scaling up the Spark EV would be 234
30kWh LEAF @ 107 would be 214
Model S 60 = 208 or 210 (est) depending on vintage
Model X 60= 200 (est)

Pretty good framework to work from. Factor in weight, frontal area, CD and regen efficiency and make your guess.

My guess is about 220miles (~350km). That's based on the probability that GM marketing said to the engineering team "make a 200-mile EV for as cheap as you can". If the car has a lot more than 200 miles of range it means they used a bigger battery than they needed to and that means the car would be unnecessarily expensive. I think the GM engineers are good enough not to err more than about 10% on the "safe" side of the target range.

Where I might be wrong is if they deliberately built in extra battery capacity for competitive reasons - so for example they could up the range by adjusting the battery's min/max State Of Charge buffer if Tesla had announced a higher range for the Model 3.

Somebody took 235 miles as the EPA range, which would have been my first guess.

Can I make a guess, EPA range will be 240 miles (384 kilometers) please?

Considering the extra weight of the 60kWh battery pack, extrapolating the Bolt range from a 20-24kWh pack, might be too optimistic. I would have adored a 2sp. manual transmission to gain at least 10% better highway range. Failing this tho, I understand that range will increase dramatically as speeds decrease from highway & freeway speeds. If EPA range won't be greater than say 210 miles at highway speeds, the range will increase a lot at 35mph. Many of the roads I travel are slower backroads & range should easily approach 230-240 miles on such roads..... still would have enjoyed the 2sp. manual tranny.

I'm guessing 220-225. If Tesla is suggesting 215 for the Model 3 (which has a sub-60kWh battery) then the Bolt should exceed that.
