"39 million gallons of fuel are used per year
for every extra pound."
10/9/12, "Allstate: Overweight Drivers, Passengers Hurt Vehicle Fuel Efficiency," insurancejournal.com
"The growing average weight of Americans is responsible for millions of
gallons of additional gasoline used in the country every year, according
to Allstate.
Allstate observed there’s a complex struggle between fuel efficiency and
vehicle weight. The insurer stated on its blog that federal regulators
are requiring 54.5 MPGs for cars and trucks by 2025.
New cars are incorporating materials such as lighter high-strength steel
and lightweight aluminum to cut vehicle weight. And replacing CD
players with MP3 players and exchanging bulky owners manuals with a
digital version on flash drives or iPads are also reducing vehicle
weight.
But even as the automotive industry goes to extremes to shed weight,
heavier drivers and passengers are adding unexpected pounds.
Allstate states that the growing trend of American obesity is adding
unexpected weight to vehicles, making it difficult for consumers to
realize fuel efficiency gains.
The insurer observed that 39 million gallons of fuel are used per year
for every extra pound added on for the average driver/passenger weight.
And the average weight in the U.S. continues to grow, the company
stated."...via commenter to WUWT
