Today's "Rescue Bots are Built Different" tidbit comes from the episode "Tip of the Iceburg."
When the Subzero-Expander explodes and freezes everything within a two-mile radius, we see the rescue bots trapped in the blast and flash-frozen in place. However, other than being cold and unable to move from the layer of ice over their bodies, they seem to be alright, and almost immediately ready for action once their ice-shells are defrosted-
-Unlike the Autobots in Transformers Prime, who start shutting down quickly after being in the cold for what appeared to be just a few hours.
It may be that the RB weren't exposed to the cold for as long, but I feel like the level of cold that hit and flash-froze them in a matter of seconds would've been more devastating to their systems than a slow exposure to elements that chill over a longer period. (Like the difference between sitting on a hot sidewalk barefoot for extended periods vs touching the rack of a preheated oven for just a brief moment)
But another thing we see is that the Rescue Bots are capable of shivering, which- like humans- would allow them to keep their core temperature up. We do not see the Autobots capable of this.
