The BMW i3 saw 538 deliveries, roughly on par with its average so far in 2017, for a year-to-date total of 4,635.
The battery-electric Volkswagen e-Golf racked up only 187 deliveries, its lowest monthly total since March 2016, while the Audi A3 e-tron plug-in hybrid sold only 85 units, its lowest since December 2015, the first month it went on sale in the U.S.
The Smart ForTwo Electric Drive, on the other hand, soared to 123 units in the second month of availability for the entirely redesigned electric version of the two-seat city car.
Plug-in hybrids with sales of more than 100 units last month included the Mercedes-Benz C350e at 126 sales and the Porsche Cayenne S E-Hybrid at 124 units; the Volvo XC90 will likely join that list as well.
Two new plug-in vehicles have entered the market recently: the Volvo XC60 T8 SUV went on sale in July, joining its larger XC90 T8 sibling, which has been available since August 2015.
For September, Volvo delivered 236 XC90 T8s and 97 XC60 T8s, bringing their respective year-to-date totals to 1,450 and 175.

Also, the Honda Clarity Electric—the 89-mile battery-electric variant of Honda's electrically driven mid-size sedan better known for its Fuel Cell version—followed in August.
That month, 33 were sold, followed by 52 last month, for a total so far of 85 units. That compares to 447 Clarity Fuel Cells sold since January.
The plug-in hybrid Clarity will follow late this year, and Honda expects that to be by far the volume leader in the Clarity lineup, with sales perhaps as high as 20,000 units a year.
Finally, Ford sold 131 units of its Ford Focus Electric compliance car, bringing its year-to-date total to 1,468.
We'll continue to update this article as final September sales data comes in.
EDITOR'S NOTE: As of May 2017, this monthly report covers only plug-in electric cars with sales of 100 units a month or more—with occasional exceptions for new models, exceptionally large changes in sales volume, or other newsworthy events.
