Per EV-Volumes: "By its growth contribution, the Tesla Model X must be regarded the most significant vehicle this year."
Tesla Model S sales increased by 22 percent in 2016, making it the sales winner, with 28,821 units sold
“The volume increase in 2016 can be attributed to Tesla (+95 % for S & X combined), the new GM Volt (+61 %), Ford Fusion (+63 %) and a number of newcomers, mostly in the Plug-in Hybrid category. By its growth contribution, the Tesla Model X must be regarded the most significant vehicle this year.”
EV-Volumes tracks sales of plug-in hybrid and electric vehicles. For the U.S., the ZEV states accounted for 63 percent of overall plug-in sales, 50 percent of which came from California (EV-Volume counts anything with a plug as a plug-in, regardless of whether it is a BEV or a PHEV). To put it in perspective, more than a quarter of all U.S. car sales come out of those states.
Overall U.S. sales exceeded 150,000 for 2016, with the top five EVs making up over 100,000 of that number.
Going forward things should improve significantly. 2017 will see a full year of Chevrolet Bolt sales in the books (although it won't be a full year graced by widespread availability), a full year of the Toyota Prius Prime, and possibly, if Tesla comes through, we will see a healthy number of Model 3's on the list. EV-Volumes predicts 250,000 plug-ins sold in the U.S. for 2017, if Tesla can get 50,000 Model 3's on the road this year.
