I've been driving my car for a few months, and it's using less energy than expected. I get about 3 miles per kWh, and can usually drive for 200 miles on a full charge.
I've been mainly sticking to highway trips, and with the A/C running, I was averaging around 3.0 to 3.3 miles per kWh. But now that it's colder, I’m seeing that drop to about 2.7 miles per kWh. Brrr!
Sorry to hear about the range. It really depends on how you drive, stuff like speed and AC usage can make a difference. Give it some time and see how it goes!
