Probably the new rating they're using with the 'updates to the motor control' they've discussed.
I doubt anything has changed.
If that's actually the case, I'm curious what the RWD-only model should update to. Unless the motor control only affects the induction FWD motor, it should improve RWD stuff as well.
Two days ago mine showed 298 P3D- of rated range, which is higher than it has showed in months. Now today with 32% charge (not sure if that matters), it shows a rated range of 288. What the hell? I think I’m going to ignore this rated range silliness.
I use Stats, and it has the calc just like teslafi of the rated range. I am aware of estimated, and that is not what I’m quoting above. My rated range fluctuates daily from 292 to 295. A couple days ago it finally went to 298 now 288.You are confusing rated range with projected range. The projected range is basically a random number generated by the formula:
Rated miles remaining * 245Wh/rmi / (Last 5/15/30 efficiency in Wh/mi)
I would just switch to miles instead of percentage if you want to see a more accurate estimate of your energy remaining (and ignore the Energy Consumption screen). But if you prefer % that is cool.
Regarding the OP - good that they did not update the Performance. Probably with a low take rate they technically could have. Good that the rated range improvements (which are presumably real) are coming to AWD vehicles. I would assume there will also be an increase in rated range with the Performance. Presumably this will be implemented as a change in the consumption constants, and a corresponding actual real improvement in efficiency. Energy available will presumably remain the same as always, but I guess we will see if they changed the discharge minimum/maximum voltages.
Yep. I prefer percentage. I wish it were showing something like 32.9, 32.6, 32.3, 32.0. Just so we know where we are since 1% = 3.1 miles (rated). That would make it inline with when you have the miles showing, instead of % (I’m repeating myself from another post).This is a big reason why I prefer the battery percent remaining showing instead of the mileage range.

Holy crap that is a huge image. Sorry about that.
Just so we know where we are since 1% = 3.1 miles (rated).
I see performance stayed at 310 miles. I hope my p3d- will get the bump and they kept performance at 310 due to tires and wheels.
I mean 1% rated range based on their site. Clearly my “mileage” varies. I’m using it as an example.This isn't true, BTW. For you, 1% = 2.88 rated miles, for example. The meaning of 1% is different for everyone.
Anyway, in regards to the original topic, I don't think there is any way they're going to be able to fudge the EPA numbers without an actual efficiency improvement. At some point they'll have to do a new EPA submission to support this change, I think. They are allowed to use a different formula than the 70% formula, apparently, with EPA approval, so I guess that is a possibility, but it seems doubtful they could get that much without an actual efficiency improvement. And I don't think the "'regen' to 0mph" change is likely to recapture NEARLY enough energy to result in such an improvement - there is nearly zero energy available from 6mph to 0mph (it's proportional to velocity squared!). I think it must have to do with the actual excitation of the motor and efficiency improvements there.
No new documents in the EPA system yet.
So without moving the car, sitting in the garage, it’s now down to 30% and rated range is 282 (at 100%), so i will charge it up sometime this wknd, and see what the rated range shows at 90% or 100%, just to see if the percentage has an effect on how the batteries are able to report, or are read, to/from the BMS.Two days ago mine showed 298 P3D- of rated range, which is higher than it has showed in months. Now today with 32% charge (not sure if that matters), it shows a rated range of 288. What the hell? I think I’m going to ignore this rated range silliness.
