Summary
The European market for diesel-powered vehicles has seen tremendous growth over the last ten years. This trend is driven by the superior fuel economy and reduced CO2 emissions of diesel engines, tax policies that favor diesel-powered vehicles, and emission regulations tailored to the capabilities of the diesel engine. The diesel growth observed in Europe has not been reproduced in the United States due in part to an economic environment that does not favor diesel-powered vehicles and U.S. light-duty emission regulations primarily based on the capability of the gasoline engine. This paper discusses the challenges associated with diesel market expansion in the United States and the technologies being developed to address these challenges. The paper concludes with an assessment of the potential for future U.S. diesel vehicle market growth.
