In just 2014 alone the nations comprising the 10-largest plug-in electrified vehicle consumers added 293,245 new PEVs to the road, significantly increasing the cumulative total to around 712,000 since 2003.

At the end of 2013 there were an estimated 405,000 PEVs sold among all nations which means things are accelerating, even if in other quarters promises and projections have not been met. It’s a shakeout, and for the second year in a row, we’re listing the world’s top six.

These leading half-dozen countries account for 85 percent of the total, or an estimated 255,678 units for calendar year 2014.

Our counts vary by country to include either just passenger vehicles, or in other instances, a few commercial vehicles are counted. In one small country, a few used vehicles are inseparable from the tally and in another PHEVs are excluded because these are inseparable from regular hybrids.

Those variables are relatively minor, and overwhelmingly this is about new passenger all-electric and plug-in hybrid vehicles.

Other footnotes up front include we’ve chosen to distinguish between fifth and sixth place which could just as well have been declared a virtual tie, but we’ll explain the rationale for naming one over the other in the article.

And, if you’re curious about places 7-10, these are: No. 7, UK, 14,518 passenger BEVs and PHEVs – after growing 305 percent in 2014; No. 8, Germany: 13,049 BEVs and PHEVs; No. 9, Sweden, 4,938 vans and PHEVs – comprising 1.43 percent of the national market; and Canada, 5,062 BEVs and PHEVs.

And now, here’s the lowdown on the top six for 2014:
