I accompanied my father today to bring his 85 in for his 5,000 mild tire rotation. They gave us a 60 and being in hot South Florida we immediately noticed the AC fan maxes out at 7 vs. 11 on the 85. I searched the forum and the tesla site for confirmation that this is indeed correct and could not find anything. When the service guy dropped of our 85 we asked and he confirmed the AC Fan is indeed less powerful on the 60. If you live in a hot climate like Florida this is an important difference and a big consideration when configuring your car. So, let it be known, the 85 has yet another benifit that the 60 doesn't.
