The range will vary according to how you drive, brake, whether or not you are using the heat or air conditioning, and anything else that uses energy. It can give you guidance on one of the displays as to how you are braking and accelerating to conserve energy.
That’s part of what makes these cars fun to drive – it’s a challenge and you will get better at it as you go along.
Interestingly, once I got my snow tires off and got the “regular” tires put back on, my range increased 5 to 7 miles per charge. I now get around 32 pure battery miles, when it was averaging around 25 before. Odd, but I’m not complaining!
