Manitoba publishes some worthwhile reports, for some reason. But under what circumstances was this data collected? Is it just trip fuel economy data from .mb's fleet of Priuses, lumping together trips of different kinds on different routes? It looks like it, and it looks like it's not instantaneous fuel consumption in kilometer #10, for example, but trip fuel consumption for a 10km trip. Therefore, it doesn't really show how long it takes for instantaneous fuel economy to reach its peak, i.e. how long it take to warm up the car.
Why does .mb's fleet get better fuel economy when it's 4.1-23.9°C out, and FE drops when it's hotter than 24°C out? I dunno, but I bet it's because the battery is too hot to provide excellent regenerative braking.
My gut feeling is that you'd get more mileage out of preheating the battery (by grid charging, perhaps?) or the ICE, but heating the tranny can't hurt.
