The sales trend line for battery-electric vehicles has been inching downward in the US since the Trump administration discontinued $7,500 federal tax credits last fall. The industry sold 244,000 new EVs in the second quarter, down 22% from a year ago, while used EVs reached an all-time high in the second quarter with 128,000 deliveries, according to the latest report from Cox Automotive. But automakers had been banking on brisk sales of new EVs by now, and that has not happened yet. That is, save for one curious outlier defying the odds.
