Out of curiosity, if you tell the car you have different tires, does the rated line move?
I suspect Tesla may be showing EPA values for the P's in alignment with the tire size.
Was wondering the same thing - in the past it has not made a difference, but given the 2020 different EPA ratings for different tires, they may be in the midst of implementing that.
293 rated miles would be consistent with a Dual Motor with
19” wheels which will soon receive a range boost to 304 rated miles. (304/322*310 = 293)
You’d expect the 3P+ to be at 299/322*310 = 288rmi.
And regular AWD/Stealth with 18” selected would be at:
310/322*310 = 298rmi
With corresponding changes in the constants to maintain equal energy.
In the future they potentially will roll an update scaling up all the above miles by the ratio:
322/310, while scaling down the rated line and constants by the ratio 310/322.
Would result in rated miles (assuming a 100% capacity battery) of:
18” 322rmi
19” 304rmi
20” 299rmi
As per the EPA numbers. We’ll see.
To start with it would be good to get those Energy Screen pictures - with rated miles, not %, showing. Along with details of the exact car configuration and wheel configuration currently selected for your car. Does the OP here have a 3P+ or a 3P Stealth (and which wheels)?
————— Part 2....
Perusing plot above, it does seem likely that the constant has changed. Assuming 293rmi for 100% in the picture above, the numbers don’t align with my list above (they are off by the ratio 293/288 for the 3P+), but it is close...
One explanation would be that they have made more energy available from the battery for part of this upcoming (2020 only?) range increase. That would explain it.
For the 3P+, assuming the above picture does represent a vehicle with 196 rated miles remaining (67% of 293rmi), it looks like we now have:
265Wh/rmi * 293rmi = 77.6kWh. (Compare to prior 76kWh number (310rmi * 245Wh/rmi).
So if that’s the case, then we’d expect an efficiency improvement with an upcoming software update of only 299/293 = 1.02 or 2%.
And with an imminent update we might see that charging constant (5Wh/mi less than the rated line) drop to 293/299*265Wh/rmi = 260Wh/rmi for 3P+.
For the other vehicles we would be looking at:
20” 3P+: Eventually 260Wh/rmi, should show 293rmi at 100% currently with charging constant 265Wh/rmi.
19” 3D: Eventually 255Wh/rmi, but should show 298rmi at 100% currently with charging constant currently 260Wh/rmi
18” 3D/3P: Eventually 241Wh/rmi, should show 317rmi at 100% currently with unchanged constant of 245Wh/rmi
This could all be a bunch of nonsense. We need data of course.
