WASHINGTON – While modern cars are getting lighter, drivers are getting heavier – and America’s fuel economy may be feeling the weight.
The Allstate Blog says that obese Americans are wasting more than 1 billion gallons of fuel per year, Forbes reports.
The Department of Energy says an extra 100 pounds lowers a vehicle’s mpg capacity by up to 2 percent.
Automakers are using less steel and lighter plastics to reach higher fuel standards, but more than a third of adults are obese and that number is expected to increase.
The issue is already a concern for the airline industry, which says it used 350 million more gallons of fuel in 2000 than in 1990 because it was hauling more weight.
