Energy Efficiency question

[MikeC]

Hi,
I took delivery of a 22 GT demonstrator in October and live in North Carolina where the weather is relatively mild. Having owned a Tesla MS for 6 years, I know that energy efficiency declines in colder weather but what I'm experiencing with the GT seems extreme. In mostly city driving on the "smooth" setting and 19" brand new fully inflated tires with temps in the low to mid 40s, I'm averaging 1.2 to 1.6 kwh/mile. Is that normal? I appear to be losing as many miles in range as I actually drive. It was bad in the Tesla, but not that bad. Any words of wisdom?

Can you go to your car settings (the gear) and tap vehicle, then trip information and take a pic? And then post here so we can see some other numbers?

Welcome to my world, although not as bad as yours. The only way I can get over 2.5 is doing highway at 65mph.

Wow, that was fast! Just so you know the 1.65 number is just in the last 11 miles since the last charge. The lower numbers are a better indication of what I've been getting mostly when temps are above 50.

That is not normal. In temperatures in the low to mid 40s , I think you should average anywhere from 2.5 to 3.0, in city driving.

That is since last charge, which is not an accurate measurement of m/kWh. I would reset your trip meter and see what kind of numbers you are getting.

Did you preheat the car or did it sit while “on” for any amount of time? My since last charge numbers are always bad, compared to my trip miles ( when the car is actually being driven )

No, and I only used the heat to take the chill off the car for about 5 minutes, though I did use one seat heater.

Was it excessive stop and go , with lots of idling?

 

[MikeC]

It was in-town so there were stop lights, but nothing to take notice of. This isn't a problem in town because I can charge at home, but it concerns me about what the real range of this car may be in cold weather. At this rate, it won't be much better than my Model S with a 75 kw hour battery!

I would not be too worried; I ignore since last charge numbers, as it’s always demoralizing.

For the last month, in temps 0-30, I am averaging 2.7 m/kWh while driving.

Since last charge is much worse, but I disregard it because it accounts for preheating , sitting idle. , etc. Also, in your case, you had just started driving and I suspect your numbers would improve with additional miles.
