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!
