Transportation Secretary Norman Mineta has unveiled the Administration’s proposal for a slight increase in the average fuel economy standards for light trucks. The standard of 27.5 miles a gallon (8.6 liters/100km) for cars doesn’t change under today’s proposal.
The increase will save consumers 10 billion gallons of fuel in the first three years, according to the Secretary. That works out to approximately a 2% reduction. (The EIA projects that by 2012, the US will be consuming some 211.9 billion gallons of gasoline and diesel per year.)
The biggest change is the creation of different size categories and associated fuel economy standards for light trucks.
Under the plan, automakers may opt to meet six separate standards based on truck size for 2008 through 2010 models or stay with a single fleet-wide target, which for 2006 models is 21.6 miles per gallon (10.9 l/100km). Automakers will be required to meet the six separate standards starting with 2011 models, when the target for minivans will also rise to 23.3 miles per gallon (10.1 l/100km).
The rule proposed today must be implemented by April to give automakers time to meet the new standards starting with 2008 models.
More detail and analysis to follow.
