Hi. We got a 2018 Model X 75D this week. We can charge it on 3 pin but won't have a wall charger for 2-3 more weeks, so I was going to just take it to a local fast charger once per week. However after filling the car to 90% on Wednesday, today (Saturday) we got the car down to 13%. Having only travelled 57 miles, From a total usage of 27.6kwh. What can I do to improve that? What happened to the other 35-40kwh?

I don't really mind if the local range is 100-150 miles but I think we are going to struggle with 60 mile range. We are currently doing a lot of very short journey... But I'm hoping I have a wrong setting or something as this seem ridiculous especially as the weather has been 7-13°C rather than the - 5°C of last week.

I’m not a Tesla expert, but the “75” probably doesn’t have 75kwh usable.

if you’re preheating before driving that will use a lot of additional energy, and doing short trips also uses a lot of energy as the battery and the cabin take a lot of energy to get up to temperature.

Likewise not a Tesla specialist...but there are many reports of them having a very high standby energy usage. Sentry mode is the main culprit, apparently. Try disabling that and see if it helps.

485 w/h per mile is heavy consumption... That should mean 2 miles per kWh ish so there is missing energy as with a fully charged battery of only 70kWh usable you should be more. Supposedly the 75s have 72 kWh usable so a very small buffer.

Also check the tyre pressures are correct. That makes a silly amount of difference on an EV.

There's one journey of only 123 watts per mile. Is that the journey back home?

I'd think it it's possible if the car hasn't been used for ages and has been stood around in cold temperatures the first week it will be using extra energy to get back to normal so it might be the worst you see.

With such short journeys it won't ever be very economical unfortunately.

Hi
There is no pre heating as I don't have access to the app yet. We live on the top of a hill and are moving to the side of the hill in a weeks time. So lots of 1-1.5 mile trips up and down the hill to see contractors and tradespeople etc. Tyre pressure is 43 or 42 in all. The X has been in use before I bought it. It racked up 1000 miles in the 3 weeks before I got it.

ok, then main thing to do, turn off the climate control and use the seat heater. Nothing is getting warm in 1 mile!

Does it drop between rides (so vampire drain) or is all power spent during trips?
