Obama unveils 35 mpg requirement at GM factory

During a visit to a General Motors factory in Ohio today, President Obama formally unveiled new fuel economy regulations governing cars produced through 2016.
 
The new rules include the first federal limits on carbon dioxide for cars. Limiting carbon dioxide directly limits how much fuel a car can burn. The standards will set different fuel economy targets for different sizes of vehicles and will set individual mpg targets for each automaker based on the mix of vehicles of different sizes that it produces.
 
Overall, the targets will require that passenger vehicles average 35.5 mpg by 2016, broken down to 39 mpg for cars and 30 mpg for pickups, minivans, and SUVs. By 2012 new cars and trucks have to average 29.2 mpg. This will require a 40 percent improvement over current cars.
 
Automakers had a part in drafting the standards, which constitute a compromise between older federal standards and those proposed by California, which 14 other states signed onto. General Motors issued a statement saying in part: "Greater consistency and certainty among a variety of regulations will help a new GM execute its current product plan centered on new technologies and more highly fuel efficient and quality cars and trucks."
 
Automakers including GM, Ford, Chrysler, have said they cannot meet the new regulations without selling electric cars, and are rushing forward with plans for electric cars and plug-in hybrids.
 
Some analysts, however, are still suspicious of the automakers' involvement in the rulemaking. Dan Becker, Director of the Safe Climate Campaign at the Center for Auto Safety, says, "The devil is in the details. Detroit's lobbyists have done their best to riddle this decision with credits and other loopholes. We urge the Administration to close these loopholes or implement an automatic backstop to ensure that the president's promise of 35.5 mpg average vehicles in 2016 will be kept."
 
In a recent survey by the Consumer Reports National Research Center, more than 80 percent of Americans said fuel economy was the most important factor in choosing a new car. And used car buyers ranked it second behind price. (Read: " Survey: Car buyers look to buy American, sound off on concerns.")
