The Environmental Protection Agency is launching an investigation into whether gas mileage estimates are accurate for new, advanced types of hybrid cars.
The probe centers on a generation of hybrids that can drive up to highway speeds on electric power alone. The agency’s director of the Office of Transportation and Air Quality says he worries that the EPA’s figures may not be keeping up with the latest technology.
EPA’s action underscores how the quickly evolving technology of electrification coming to cars, and a nation’s focus on gas mileage like never before, are making it harder to provide accurate consumer information that families will use for what likely some of the biggest purchases they ever make. The agency’s action comes after Consumer Reports said that the gas mileage it found in two advanced Ford hybrids, the C-Max crossover and Fusion sedan, didn’t match the magazine’s testing.
The problem, says Chris Grundler, director of the EPA’s Office of Transportation and Air Quality in an interview with USA TODAY, is that the newest breed of hybrids are extra sensitive to varying driving habits. A hybrid driven aggressive might get far worse gas mileage than a conventional car.
