The U.S. market is a unique beast as stiff pollution regulations make it impossible to sell the same fuel efficient engines found in Europe and elsewhere here. Certainly, Volkswagen, Mercedes and BMW do sell diesel powered cars in the U.S., but these engines have been modified to comply with 50-state emission requirements. These requirements are tougher than any currently on the books in Europe, holding harmful pollutants to a minimum. Naturally, fuel economy is affected as these engines must pollute less at the expense of ford fuel efficiency.
