The nation added more than 300,000 new clean diesel vehicles across the country in 2015, with the state of California leading the way with a 15.4 percent increase in the number of registered diesel cars and SUVs in 2015, according to a Diesel Technology Forum analysis of the latest Vehicles in Operation (VIO) data compiled by IHS Automotive.
Meanwhile, Texas was number one in the nation in total number of registered diesel vehicles ahead of California, Florida, Washington and Pennsylvania.
"For the second year in a row, California led the nation in the fastest growth of diesel car and SUV registrations," said Allen Schaeffer, the Executive Director of the Diesel Technology Forum. "California consumers are particularly interested in energy-efficiency and eco-friendly vehicle technologies which helps explain the sustained interest in clean diesel cars, trucks and SUVs - ones that provide proven energy efficiency without compromising vehicle performance or driving range."

The analysis is based on 2015 data of vehicles in operation (VIO) that were compiled by IHS Automotive in all 50 states and the District of Columbia through December 31, 2015. The analysis reviewed VIO data for passenger vehicles defined as cars, SUVS, full-size pickup trucks and vans. The Diesel Technology Forum used the VIO data to calculate the top states in registrations and the percentages of diesel and hybrid registrations in each state. The analysis also compared 2015 to 2014 data.
"We anticipate the clean diesel car market will stabilize and regain the momentum it had achieved earlier as a variety of new clean diesels are introduced in the U.S. in the very near future," Schaeffer said. "Auto makers have already discussed a number of new clean diesel cars, SUVs and pickup trucks they intend to bring to the U.S. market which will offer drivers an array of vehicle choices.
"We also project growth in the clean diesel market due to the new federal fuel efficiency standards requiring higher vehicle mileage because diesels achieve about 30 percent better fuel efficiency than gasoline vehicles."
7.7 Million Diesel & 3.6 Million Hybrid Passenger Vehicles Now in the U.S.
The number of diesel car, SUV, full-size pickup trucks and vans in operation reached 7.7 million in 2015 – an increase of 329,700 over 2014. Hybrid vehicles jumped 331,700 to a total of 3.6 million during the same period.
California and Massachusetts are the only two states that have more hybrid vehicle registrations than diesels.
California, Tennessee, Idaho & Nevada Show Double-Digit Growth in Diesel Cars & SUVs
According to the Diesel Technology Forum analysis, California (+15.4%), Tennessee (+14.8%), Idaho (+10.4%) and Nevada (+10%) led the nation with the fast growing registrations for clean diesel cars and SUVs (2014 vs. 2013) based on their growth within vehicles in operation.
California also has the highest number of diesel cars and SUVs in the nation followed by Texas, Florida, Pennsylvania and Washington.
