Mileage understanding

Huh? 2.4 to 1.8?

I think he intended to say the opposite....

Thank you, for catching my mistake. I corrected it.

Yes I realized that I did that now you mentioned it. Thank you. I noticed that yesterday driving my son to the airport I got 2.8 kWh preconditioning the battery and that was with the air conditioner on.

My precondition does not involve AC right now

Print, Cut, Paste over your Guess-O-Meter. Problem solved.

Need a big town / small city driving, because I get around 3 when driving to/from work. A lot of 35mph driving with a little bit of 45-55.

This subject has been a huge frustration for EV and hybrid Mfr’s for decades. The 2004 Toyota Prius was originally rated as a 60mpg car. That was true at 60mph or less and driven delicately.
But the average consumer didn’t drive like that, and complained like hell that Toyota was misleading. They later changed it to like 48mpg.
Sad, because I could consistently get 60mpg.

(If exploited with extreme driving techniques, hypermiling with outrageous speed fluctuations , it could get 100mpg. Yes 100mpg !)

It’s been the same struggle with consumers, conditioned by gas cars, ever since.
Bottom line, EV drivetrains are extremely efficient, but extremely affected by the “varaiables”…., which are many.

Kind of reminds me of an old S10 I had, with the 4.3l v6, manual, single cab, I was always getting 20+ mpg (often 25 or more) even with cold conditions. The State I lived in at the time had kind of low speed limits, so that helped, but I was always surprised what good mph it got vs what the EPA rated. Also, I wasn't hypermiling at all, I was in my early 20s, so you can guess how efficient I was driving.

Getting (recently) 2.4mi/kWh cool weather (50F) 25mph gradual accelerations and stops.

Half what my 2012 Nissan Leaf gets under same conditions (4.8mi/kWh) in ECO mode.

Leaf wt.: 3401 lbs
Lightning wt.: 8250 lbs

I assume the weight, i.e., the road/tire friction and inertia (to get it moving), it adds are the main reasons - wind resistance at 25 would be a pretty minimal factor, though not zero.
