EPA challenges Smart Car's claims

The Smart car may not be so intelligent after all. After claiming to get 60 miles per gallon, the EPA clocked it in at a mere 37 mpg:

Zap made a big publicity splash with its plans to sell the tiny two-seat coupe, promoting it as the most efficient gasoline-powered vehicle ever at 60 miles to the gallon and lining up thousands of orders.

But before the French-made ultra-mini could even think about hitting U.S. roads, the Environmental Protection Agency ordered the Santa Rosa, Calif., auto importer to scale back its fuel-efficiency claims.

The federal agency's fuel economy estimate for the Smart car isn't 60 miles per gallon — it's 37, sort of like a Honda Civic.

Steven Schneider, Zap's chief executive, said that the company's fuel trials showed the Smart delivering readings of 50 to 60 mpg and that he intended to ask the EPA for a retest. Meanwhile, Zap has pulled the 60-mpg boast from its website.
