We feature the top 10 best-selling plug-in electric cars based on U.S. sales for 2018.

 

Each month, we'll update this post with new delivery figures and rankings. Keep in mind that some automakers (General Motors and Tesla) don't provide monthly sales data, so these numbers will be estimated on a monthly basis. In addition, while BMW provides an overall total sales number for plug-in electric vehicles, the automaker doesn't split out models.

At the end of each quarter, we'll reconcile Chevrolet Bolt and Volt sales after GM provides quarterly sales data. Tesla Model 3, Model S, and Model X delivery data will also be reconciled on a quarterly basis. However, due to international sales and Tesla's lack of U.S. sales reporting, the automaker's total deliveries will still be based on estimates.
