So is this new?


So does it now heat the battery when turning on climate control? That's new isn't it?

Winter is still a long time away before we can test again!

I think the only new thing there is that it will show in blue the part of your battery you are missing due to the cold.

5.9 looks great

I got the prompt this morning and installed my ideal range is at 160 rated is a 138 I have a 40KWH so there is a change in the range calculation.

The battery & charging forum will have a lot to discuss! There have been huge debates about whether we're seeing pack imbalance or algorithm problems, especially for those with 40kWh packs who can't do a 100% range charge. Really interested to start seeing some before/after 90% and 100% range estimates!

I would typically only charge to 234 miles when not set to range mode. Work up to the software update being complete with my rated range being 239 miles. Looking forward to the battery discussion.

I have to say that reading those notes I am kinda excited. I've been waiting for a release with interesting new features since I took delivery on 5.6. This is what makes the car so awesome, glad to see we are getting back there.

You've probably heard the apocryphal story of the guy who bought a car and returned it the next day because it wouldn't do 120 mph, as promised. The dealer apologizes profusely and says that there must have been something wrong with the car; takes it back, makes a few adjustments, and gives it to the customer. The customer is delighted--he takes a test drive and now the car can easily top 130. Of course, all that changed was the speedometer calibration...


Not saying. Just saying. Since there's no way of knowing what the algorithm is, and since the algorithm appears to change with some regularity, it's pretty hard to get exercised about lost capacity...which should be both calming and a little worrisome. Ultimately, as these cars age out of warranty and move into the secondary market, someone is going to have to develop an objective and consistent measure of battery capacity.

And maybe disables the limiter.

I suspect the service center is accurate in what it's saying: the USB key (or download, or whatever) that has the new firmware has not been distributed to the service centers and green flagged for installation by them.

The distinction being: greenlighted at service centers is different from OTA release. I believe that's always been the case for Model S.

None of this implies service centers being "late to know".
