Government proposes 31.6 mpg by 2015

In celebration of Earth Day yesterday, the Department of Transportation released an updated proposal on fuel economy standards that would require cars to get better gas mileage much sooner than previously scheduled.

The new standards would require vehicles to get 25 percent better fuel economy than the current standards by 2015. Cars alone would improve to 35.7 mpg in 2015, and light trucks to 28.6 mpg. Under a new Energy Bill that Congress passed last December, fuel economy requirements must improve by about 40 percent by 2020.

This proposal puts the bulk of that improvement at the beginning of the bill’s timeframe, from 2010 to 2015. This more aggressive timeline will likely drive the implementation of advanced technologies, such as direct fuel injection, sophisticated transmissions, and hybrid drive systems. By 2015, on average, new vehicles would be required to achieve about 31.6 mpg. The new rule would set different fuel-economy mandates for each automaker, based on the sizes and types of cars they build.

The proposalis expected to encourage manufacturers to install these fuel-saving technologies in all types of vehicles, from SUVs to small cars, rather than to simply build more small cars.

For the first time, the program will also allow automakers that exceed the new standards to sell credits earned under the program to other automakers that miss the targets. Otherwise automakers that don’t meet the targets would have to pay fines. In an interesting admission, the government has also assumed a monetary cost for CO2 emissions associated with global warming, as well as an energy security cost for petroleum consumption in setting the standards.

It goes without saying that demanding greater fuel economy improvements sooner will save significantly more fuel in the long run.

The government estimates that the proposal could save 55 billion gallons of fuel and save consumers more than $100 billion at the pump.

Now that’s something we can all celebrate.
