I haven't driven my car enough at night yet to have a good comparison, and the Fit's lights are fogged over right now. However, I do have the impression the Fit headlights are better, all else being equal.

Made 47.5mpg on my way to work this morning, low 20's and with the roads being practically soup.

I think the grille block is way more important with this engine than the old one. Without it, it won't get up to temperature in this weather even without running the heater. I could let it idle for 5 minutes and the coolant would end up warmer than if I drove it for 30. I know the thermostat works, so my suspicion is that it's simply air passing over the engine block itself. Too little load, too much block surface area. With a 95% grille block in place it warms up quickly.
