Zap, the U.S. importer of DaimlerChrysler's Smart cars, had advertised 60 mpg claims helping the company secure thousands of orders but the EPA estimate is in a whole other ballpark. The EPA tests only measured 37 mpg — forcing Zap to remove the 60 mpg claim from their website. Zap is asking the EPA for a retest even though it seems that some of the customers aren't all that concerned. Smart's desirability transcends fuel mileage, size or it's 16 second climb to 60 mph. Still the Smart should be getting better mileage than a Civic.
