140,777 and Counting
According to Plug In America, the cumulative tally of plug-in vehicle sold in the US is now over 140,000 units.
National Plug In Runs All Weekend This Year
This 140,000-unit mark was surpassed just in time for the third annual National Plug In Day.
What this 140,000-unit figure tells us is that September is expected to be another strong month for sales, which we'll officially report on October 1.
Our own running tally of current plug-in vehicle sales in the US since late 2010 puts the figure at 129,013 cumulative units sold through the end of August. (click here to see a breakdown of sales by year, model and month). Then there is another 4,500ish sales for the unknown amounts of the fringe players, earlier limited runs, and Tesla Roadster and Fisker Karma sales in the US
We should note that Plug In America estimates its sales figures based on this:
"Vehicle counter based on EDTA count of U.S. sales of 130,767 plug-in vehicles (BEVs, PHEVs, EREVs) from December 2010 through the end of August 2013."
Plug In America then adds to the 130,767 on a calculated basis over the next month, meaning that its sales ticker roles in a predictable manner. Sales don't work that way (and they assume all Tesla Model S delivers are in the US - which they are not), but Plug In America's end-of-month results are usually fairly accurate.
