Consumer Reports Says Ford, GM Overstate Turbo Benefits

Consumer Reports said its tests of turbocharged cars from Ford Motor Co. and General Motors Co. didn’t support the companies’ claims about fuel economy and performance provided by the powertrain technology.

Tests of Ford’s 2013 Fusion sedan with a 1.6-liter turbo engine by the Yonkers, New York-based magazine found the car to be slower and less fuel-efficient than standard four-cylinder engine cars such as Toyota Motor Corp.’s Camry and Honda Motor Co.’s Accord.
