The Range Estimator in the Chevy Bolt EV is far more robust than people give it credit for. Join me as I share my experiences traveling with and explaining how to use the Bolt EV's Range Estimator.

As we head into winter, I’m seeing more Chevy Bolt EV owners call out extreme fluctuations in their projected range. Many of those owners tend to drive slowly – at city speeds, and their projected ranges often exceed 300 miles on a vehicle that is only rated for 238 miles of combined range under EPA testing. With winter setting in and heater usage increasing, many of those same Bolt EV owners are now seeing projected ranges of less than 200 miles.

This has led to claims that the Range Estimator that GM designed for the Chevy Bolt EV is highly inaccurate, and some have even started to refer to it as a “Guess-o-meter,” the same derisive term used to describe the range estimator in the Nissan Leaf, which was notorious for displaying inaccurate range estimates.
