Bolt EV Range Impressions

As most of you know, I purchased my Bolt EV in December, and I've put many, many miles on it.

Volt Stats

There was recently a bit of a stir as some Bolt EV owners started posting 300 miles on a charge, and some of the less fair publications started to refer to "perfect conditions." However, that had not been my impression up to this point. Southern California has had some rather wonky weather since the Bolt EVs have been released, and at best, we've seen a handful of days that approached ideal conditions. So, I decided to intentionally drain my battery pack on a weekend with very close to an even split of high-speed freeway, mid-speed country roads, and city driving.

Data video:

Sample (non-freeway) driving video:

This weekend has brought some warmer temperatures, and it just so happens that I have to drive about 500 miles from Friday to Sunday. So I'm doing some more testing. We are getting about 8 to 10 hours of 70 F weather, which I am trying to take advantage of, but my schedule doesn't always allow that. For instance, it had already dropped to the mid 50s F on Friday night by the time I was driving home. Still, with 80-90% high-speed freeway driving (65-70 mph), I was on track to hit 280 miles on a single charge.

So my impressions of the Bolt EV's range and efficiency so far are that it is actually more efficient than the first generation Volt at freeway speeds up to 70 mph. Steady state driving of 50-55 mph under ideal conditions should net 300 miles of range or 5 miles/kWh. And steady state driving of 67 mph (+/- 2 mph) under ideal conditions should net about 4 miles/kWh. I think that between spring and fall, we will be seeing many Bolt EV owners reporting 300 miles out of a charge on their daily driving. And I think that if ari_c can ever get his hands on a Bolt EV, he could be flirting with 500 miles on a single charge.

Here in hilly Austin my 1st gen numbers generally match the EPA for a mix of city and highway if the temperatures are between 50 and 90F.
And this is with my driving style being fairly aggressive acceleration followed by doing my best to drive at a steady speed and anticipate the need to slow down or stop as far as possible. So, I agree with other that the EPA numbers on the Volt at least are quite easy to attain or exceed. I am glad to hear it sounds like the Bolt is continuing that trend for GM EVs.
