When Ford announced that it was lowering the fuel economy numbers of the C-Max Hybrid a couple of weeks ago, they said the EPA's fuel economy testing was unrealistic for hybrid vehicles. The EPA has come back this week and gave a clear message: "The problem here is really not how the testing is done."

Christopher Grundler, the EPA's top auto industry regulator told Automotive News that the EPA's own engineers weren't sure if their tests were accurate due to the whole C-Max Hybrid fiasco and decided to retest a few hybrid vehicles in the summer. The results? The Toyota Prius and Hyundai Sonata Hybrid had no problems in the tests that caused the C-Max Hybrid to stumble.

"It was all quite reassuring," said Grundler.

Grundler says the EPA will likely change the rule that allows an automaker to test one vehicle for fuel economy and then share the ratings across a number of vehicles if they meet certain criteria.
