Lifetime Miles/kWh

Um.... this is my efficiency when towing.

Did you do the math?

I have my towing separate based on the trailer.

There was an update along the way for us orignal people that messed up the calculator. So you have to manually do the math of miles driven divided by total energy used.

Those that get 3.0 KwH need to live a little. Jeez!

2.31 over 28K miles. About half of that is cold driving, -20F to +30, 150 miles or so round trips. R1T is housed outside, unheated, plugged in, charged to 85% before take off. Some trailer towing also, not a lot.

Wait…. 75,000 miles just towing, on a 2024 vehicle?

not to derail this thread but could you give more detail on what you know about this "update" because mine is/has been wonkers since I started tracking Trip A and Trip B
Thanks

I don't know exactly which one did it. But you can look at the previous post before my original one and his 111,111 mile one also doesn't calculate correctly. I just cleared my trip B after 7,000 ish miles over the last 4 months and it calculated out the same.

Now what percent of the "2.1 - 2.2" club are also on the AT tires?

Also depends on climate.... possibly more dependent than tires.

I'm in a dual motor with Pirelli 21's and on a 75F day I'm looking at 2.6+
On a 15F day I'm looking at 1.9.

Your trip meters don't tell the whole story. Like Tesla, they don't seem to account for vampire drain when the vehicle is off or charging inefficiencies. I have a power/energy monitor on my home EVSE and track all charging sessions away from home as well.

Based off the trip meter on the vehicle, my efficiency is 1.72 mi/kWh, but based off the actual electricity pulled from the grid to recharge the battery, it's 1.49 mi/kWh. Most driving is at 70+ mph and I have all-terrain tires on the R1T, so I have pretty poor efficiency overall, but just pointing out the difference between the two numbers.

As mentioned, Tesla does the same. On my Model 3, with 120,030 miles, the trip meter reports an efficiency of 3.72 mi/kWh vs an actual efficiency of 3.11 mi/kWh.

If one is tracking driving efficiency, I don’t think actual power pulled from the grid during a recharge is relevant. Especially when cold, the initial power coming in goes to cabin and motor conditioning (heating), not to the HV battery. I have watched mine spend the first 12+ minutes of a charging session doing this, before it ever starts sending electrons to the battery. This can be tracked on the in-car display. Therefore, take the home energy bill with a grain of salt. It will always show more energy than actually ends up in the HVB. Because of this, factoring in energy used during a charge session will skew any actual driving efficiency calculations.

I do not understand my lifetime efficiency numbers. I have 61,918 on my 22 R1T. It shows I have used 29,852 KWH and my lifetime efficiency is 1.37 according to trip B on the truck. IF you divide the two numbers I get 2.07. This seems somewhat accurate based on what I see while driving. summer is quite a bit higher and living in MN the winters are cold and windy so it is a lot lower. Can someone help me understand the math? I am usually good with these type of things.
