The passenger car market in Iceland went down by almost 15% year-over-year during the first two months of 2020, but plug-in car sales increased by 60% year-over-year to some 634.
Those are fairly small numbers compared to bigger countries, but the market share is outstanding - 37%! That is not only huge, but also the growth is unprecedented as the year 2019 closed at 25% market share.
It's clear that Iceland as an island is a pretty good case for plug-in cars, as long-distance travel is not much of an issue.
