@Redmond Chad: Out of Spec Reviews did 100%-to-0% tests and found a maximum usable capacity of 132.1 kWh for Large Pack and 143.3 kWh for Max Pack.

Without towing anything, they found a 13% efficiency drop from 60 mph to 70 mph, and a 23.6% efficiency drop from 60 mph to 80 mph.

Hopefully these numbers will help you refine your calculations as far as you like....

Thanks, Dave. I updated my post above to use the 132kWh figure.

Thanks for the OoSR numbers too. They are pretty close to what Branden reported a year and a half ago in THIS thread. He reported 15% loss at 70mph, and 24% at 80mph. I expect the losses to be even higher when you are towing.

As noted in that thread, those numbers also make sense given similar numbers I had run for Teslas in 2009 and 2012. In 2013 I assembled as many of the factors that affect range as I could in one place; that's on another forum HERE.
