Lowering mpg tough as drivers pack on weight

By Cornelius Nunev


Vehicles burn less gas if they are lighter. Car manufacturers are working relentlessly to lower the weight of cars. However, as Americans pack on the bulk, those endeavors may be in vain, according to a recent article and associated infographic.

Gasoline amount depends on weight

Car makers have been trying really hard to get automobiles as light as possible to be able to meet future fuel emission requirements put into place by the government. The only problem is that Americans are gaining weight as automakers are dropping it off the cars, which may make it nearly impossible for politicians to get what they are hoping for.

Requiring fuel for it

Between 1960 and 2002, billions of gallons of gasoline were used due to the extra weight of overweight Americans in automobiles, according to a blog post at Allstate insurance and Vehicles.com. The Entrepreneur Magazine did the study.

Allstate explained:

"Americans keep gaining weight and cars are losing it. It's a seesaw battle that's making it difficult to realize the gains expected by a push for lighter, more fuel efficient cars."

Every 2 pounds of weight

The U.S. EPA explained that a car loses 2 percent fuel efficiency for every 100 pounds it carries, though that may seem ridiculous.

The passenger inside must also impact fuel efficiency then. It makes sense that there would be negative effects for the passenger's weight.

CAFE standards

From LA to Brookly, Ford to Porsche, all cars have to meet the federal Corporate Average Fuel economy Requirements. Automakers have a long way to go to get there though, which is why they are working on fuel efficiency in engines and reducing weight of automobiles with lightweight materials. Right now, automakers typical about 42.8 miles per gallon on cars being produced. By 2025, the CAF standards require that every car has to get at least 54.5 miles per gallon.

Getting larger

About 35 percent of Americans are medically defined as overweight while the average female is now 160 pounds and the average man 196 pounds, according to a Gallup poll from last year. Since 1990, the typical American has gained about 20 pounds.

A poll at AOL Autos points out drivers typically want larger cars because it keeps them from feeling crowded. That just makes the issue worse.
