Washington, D.C. – Sales of clean-diesel automobiles in the U.S. increased by 27.4 per cent in 2011 over 2010, according to research firm Baum and Associates.

“Without a doubt, 2011 was a key year for the industry’s effort to reestablish clean diesel automobiles in the United States,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “This 27 per cent increase in annual sales is a strong sign that American drivers are understanding the benefits of new clean diesel technology in terms of better fuel efficiency and reduced emissions.”

The 27.4 per cent rise in diesels was in a market that only increased overall by 10.2 per cent. In December 2011, diesels were up 16.2 per cent over December 2010, compared to an increase in hybrids of only 8.7 per cent.

Diesel vehicles coming to the U.S. market include versions of the Jeep Grand Cherokee, Cadillac ATS, Porsche Cayenne, Chevrolet Cruze, Mercedes-Benz S-Class, Volkswagen Passat and Mazda, which will become the first Asian car manufacturer to sell diesel cars in the U.S.

Baum and Associates expects diesel car sales to grow to 6.0 to 6.5 per cent of the entire U.S. market by 2015, compared to just over 3.0 per cent today.
