When you say engine performance, does that factor in drop in battery capacity? I know diesels also have problems running (and getting up and running) cold.

If you have a Tesla, that’s the fridge-like noise you hear when you warm it up. Diesel engines typically run (inefficiently) to warm themselves up and be efficient, but that is a larger energy cost, mainly because that process captures a fraction of the heat from the combustion.
