According to data from the U.S. Department of Energy (DOE), plug-in vehicle sales increased 40% in 2016 to approximately 160,000 units.
In 2011, the first full year of sales for mass-market plug-in vehicles in the U.S., nearly 18,000 plug-in vehicles were sold across the country.
Since then, sales of plug-in electric vehicles have grown nearly each year after, increasing nine-fold to a record high in 2016.
As reported by the DOE, full-electric vehicles outsold plug-in hybrid electric vehicles each of the past three years.
