One of Ferdinand Porsche´s reasons for choosing an air cooled engine for both the VW and the Porsche was that it was a reliable winter set up. No freezing water cooled engines in chilly Germany winters.

They are very well suited for cold environment, although the heating for the cabin in the early models are perhaps not the best. Takes a little longer to get warm inside.

Salt is another matter. No good on the old metal.

Another thing is that the rather more dense cold air will at least theoretically produce a higher output. On cold crispy days it always feels like my car is faster.
