SURPRISING 50 MILE Range Boost in a 2017 Model S60D With 17.17.4 (?)

[Jim Holder]

Hi All!

Finally got the update to 17.17.4 last night and much to my surprise after charging to 100% my range displayed 270 miles (!) when it normally maxes out at around 219. So I drove it around for a bit and it's still up there in the 260's...

My average Wh/mi of 360-380 is accurate (see the display on the right for the past 15 miles is still there from yesterday pre-update), so it can't be a misreading by the system (or could it?).

Could it be the new FW uses a new algorithm for calculating range (not mentioned in release notes) OR after a FW update the car needs to calibrate again and soon my "range" display will fall back to where I remember it (around 219 miles on 100% charge)?

Anyone else see a range bump?

Perhaps you've been switched to ideal miles?

 

[McRat]

It appears to be the number for the 75D?

OMG! You are right. I just checked. "Ideal" was selected somehow during the update. Boo! Now showing 210 again....
Sorry for the false excitement!

Lol, ever hopeful....

I gasped when I saw your picture, that's about what my 85D gets at near 100%! Would have been crazy awesome if true!

It is true, it's ideal miles!

Like in an ideal condition.
Going down the road at 50mph with no traffic
Downhill
The whole time
With no wind
No passengers
etc.

A bug where they accidentally unlocked the full battery?!

Yet another reason to switch to battery charge percentage instead of indirect projected "future miles."

 

[Stiction]

I personally think charge percentage is not as good as rated miles.

Get in another EV and rated miles will still mean something: You can drive and know what to expect
because rated miles is a unit of energy calibrated to the cars performance.

XX% means nothing. How big is the battery? What is the energy per mile? You have a
lot of learning to do to figure out how far you can go.

Ask yourself this question: will you travel the same number of miles for a given battery charge, regardless of speed?

Temporal context is everything.

Have you ever driven an internal combustion engine vehicle?
