Globally, EV Sales estimates, the Chevrolet Volt extended-range plug-in has moved about 88,000 units, while Toyota has sold about 71,000 of its Prius Plug-in Hybrid vehicles worldwide. Fourth-place Tesla Model S is close behind at about 66,000 units.
Among automakers, Nissan is also by far the lead dog, but Mitsubishi has leapfrogged Chevrolet among plug-in vehicle makers, as the Outlander Plug-in Hybrid continues to sell well. Impressively, the relatively new BMW i3 has moved almost 23,000 units since its debut in Germany last year.
As for Nissan, company chief Carlos Ghosn said at the New York Auto Show earlier this month that the company could sell as many as 50,000 units a year of the Leaf in the US, provided that charging infrastructure throughout the country improves. Earlier this year, cumulative US Leaf sales moved past 75,000 units since its late-2010 launch.
