Hi Tony and all,
You too hit on something but also missed the mark. The reason any
internal combustion engine delivers higher performance on cold days is
the thermal expansion ratio. When you go from cold to hot energy is
produced not by the heat but by the flow of heat from cold to hot, it's
called thermodynamics. The colder you start with and the hotter you end
up with the more energy is produced. This is why the liquid hydrogen and
oxygen engines on rockets like the Space Shuttle are the most powerful
and efficient in the world.
Now just think about a car with such an efficient non polluting engine.
The greenies would be tickled to death with the possible exception of the
one tailgating you.
