"In June, there were 103 Chevy Volts and 46 Nissan LEAFs registered in Maine, according to state motor vehicle registration records."
That's per the Portland Herald Press.
As the statistics show, since launch, the Chevy Volt has outsold the Nissan LEAF by more than 2 to 1 in Maine.
The top three selling plug-in vehicles to date in Maine are the Volt, Toyota Prius Plug-In Hybrid and Nissan LEAF.
Unfortunately, obtaining accurate sales figures is difficult due to this:
"The records do not indicate how many other plug-ins are on Maine roads because records do not differentiate when a car model has an electric version, a gasoline version or a hybrid version."
So, for the Prius Plug-In (as well as other plug-ins), exact figures can't be obtained.
We did however discover that "there were 300 plug-in electric cars in Maine as of last September, 40 percent of which were in the Greater Portland area."
And that concludes this round of what's become tradition now at InsideEVs: presenting obscure plug-in sales data.
