Here's the scoop.
My battery now charges to about 265 at 90%, and at 90% the battery charges to 88%. Per the percentage, this is a battery degradation of 2%. Per the mileage, this is a battery drop of about 5% which would be pretty high for a car that only has about 8k miles.
Here's the twist:
I've noticed on the tesla website that you can now order a performance in 2 flavors, one with 322 miles of range and a lower max speed, and one with 299 miles of range with a high max speed.
When I ordered mine, it said 310 miles of range and max speed of 162.
Since mine was the higher mph, does that mean that my EPA rated range was since modified to 299? Which would more accurately correspond to the estimated range that I'm seeing?
I called Tesla about this and (let me preface this that any talk with these guys about battery stats seems like they are being extremely shady) they said that my performance was going to be soon getting a software upgrade to 322 miles. (this was after the lady had to put me on hold to go ask someone, so who knows how accurate this information was).
By the way, I don't buy that the battery estimate is partly a function of driving, because mine has gone down quite a bit and my lifetime kwh is just under 230, which should correspond to a range over 310 with a fully functioning battery.
Anyone know anything?
