Electric vehicle sales in Connecticut declined sharply in late 2025, though the state continued to outpace the national average, according to a new report from the Alliance for Automotive Innovation.
EVs accounted for 6.8% of new light-duty vehicle sales in Connecticut in the fourth quarter of 2025, down from 13.44% in the prior quarter and 12.42% a year earlier. A total of 2,407 EVs were sold in the state during the quarter, ranking Connecticut 12th nationwide for EV market share.
For the full year, EVs made up 10.42% of new vehicle sales in Connecticut, slightly above the national average of 9.6%.
Nationally, EVs represented 6.5% of new vehicle sales in the fourth quarter, down from 12.6% in the third quarter and 10.9% a year earlier. There were 164 EV models available in the U.S. market by the end of 2025.
The slowdown in Connecticut came after federal tax incentives for EV purchases expired in late 2025, a shift that officials and industry observers say made vehicles less affordable and dampened demand. State rebate data also indicates a steep drop in incentive use following the policy change.
Connecticut also ranked relatively high for charging access. The state had about 75,300 EVs on the road and 4,485 public charging outlets at the end of the fourth quarter — a ratio of roughly 17 vehicles per charger, compared to 31 vehicles per charger nationally. That placed Connecticut 11th among states for charger availability.
The report found Connecticut had 750 DC fast chargers, with a net increase of one during the quarter.
