A car will normally be somewhat warm, even several hours after shutting it off. Part of that warmth is the coolant giving up heat and warming the engine bay. I imagine a Prius with vacuum coolant bottle would cool the engine bay quicker than normal cars. This is because the vacuum bottle would keep the heat instead of giving it up warming everything under the hood.

I dunno, we have a 2005 Honda Pilot and it goes cool very fast after turning it off, my MR2 cools down very fast as well. I only have to leave my car sitting for 1 hour before the coolant is close to room temperature. I'm talking about coolant, not the engine bay. Engine bay temperature doesn't matter lol.
