The top 10 plug-in sell automotive groups combine to hold more than 75% of the total ≈450,000 plug-in sales in the first six months of 2017.

The biggest supplier turns out to be Renault-Nissan-Mitsubishi, which at nearly 62,000 boasts a 14% share.

As Nissan soon will introduce the next generation LEAF (the world's best selling EV in terms of cumulative sales), the future prospective for growth is bright.

Likewise for second place Tesla, which delivered 47,000 in the first half of the year. Tesla is now ramping-up sales of Model 3, which could shoot company to the #1 when the annual list is reset to zero in January.

More than 42,500 sales are noted for BMW, in third which aims for 100,000 for the full year.  However, this won't be near enough to stay on #3 ahead of BYD, as the Chinese company delivered some 35,750, but is growing quick (more than 11,000 plug-in car sales in June alone).  In truth, neither Tesla nor Nissan are likely to stop BYD's rise to the top spot by year's end.

Toyota has benefited greatly from the Prius Plug-In (aka Prime) the past few months - in fact, the plug-in Prius is the world's best seller this year after posting back-to-back huge numbers (7,000-8,000 units) in May and June - which should help Toyota crack the top 4 (perhaps top 3) this year, while GM will need to speed up supplying the Bolt EV outside of the US if it wants to crack the top 5.
