...reflect reality, by raising the standard to 35 m.p.g., it mandates a relative increase in fuel economy of about 40%. But the government's double bookkeeping still matters - especially with the NHTSA set to issue final regulations that will help guide automakers to meet the new standard. An EPA analysis from September shows that the 35-m.p.g. CAFE standard will translate to 27 to 28 m.p.g. under real-world conditions - about the same fuel efficiency that the current CAFE standard purports to enforce. "The program is undermined and the public confidence in policymakers is undermined," says Mike Walsh, the former...
...little less than two years ago the Environmental Protection Agency (EPA) decided to revise the tests it uses to determine the official fuel-economy rating for new automobiles. It was no secret that before the revision, the actual gas mileage delivered by a new car tended to be significantly lower than what was promised by the official "window sticker" ratings. That's because they were based on the EPA's old tests, which involved little more than steady driving - without the use of air conditioning or anything else that might increase gasoline consumption...
...EPA's new tests account for faster driving, acceleration and deceleration and air-conditioning use - in other words, the way most real people drive. As a result fuel-economy ratings have dropped about 12% for city driving and about 8% for highway driving. When the new tests kicked in, a 2006 Toyota Prius, for instance, went from having a 55 m.p.g. combined efficiency rating to 46 m.p.g. - overnight...
That's partly due to the fact that while the EPA rates the fuel economy of vehicles on a model-by-model basis, the calculation of CAFE falls to the National Highway Transportation and Safety Administration (NHTSA), part of the Department of Transportation. Under the laws that have created and modified CAFE, the NHTSA isn't allowed to revise its tests - meaning it's stuck using tests that haven't really been updated since CAFE was established...
...want to help young scientists develop the skills that will ultimately help them in their professional careers and which we hope will help organizations like the EPA and state decision-makers,” said David L. Deegan, a spokesperson for the EPA...
