Clean diesel car and SUV vehicle registrations increased by 13.5 percent in 2014 over 2013, while hybrid car and SUV registrations increased by 15.1 percent, according to the latest data compiled by IHS Automotive for the Diesel Technology Forum.

California (23.74 percent), Massachusetts (21.01 percent), and Nevada (17.76 percent) were the fastest-growing states for registrations of clean diesel cars and SUVs in 2014, the forum announced.

Large population states Texas (893,553), California (650,252), and Florida (333,593) were the top states with the highest number of diesel car, SUV, pickup truck, and van registrations in 2014. These three states were also the top states in 2013 registrations.

California was the only state with more hybrid registrations (826,468) than diesel registrations in 2014. Nearly every state and the District of Columbia showed increases in diesel and hybrid registrations in 2014 compared to 2013 — except Georgia, which displayed a 4.6 decrease in hybrid registrations.

The analysis looked at registration data for cars, SUVs, pickup trucks, and vans.
