Worth the Weight?

Obesity is rampant in America. Between the Center for Disease Control’s dire reports, documentaries like “Honey We’re Killing the Kids” and endless infomercials for every diet and exercise program imaginable, it’s obvious we’re becoming a nation of Fat Bastards and Sherman Klumps. Now the Environmental Protection Agency is sounding the alarm about our cars. The EPA recently announced that America’s vehicle fleet is the heaviest it’s been since Ford touted the Pinto’s “road hugging weight” as a safety feature. Our cars and trucks, like their drivers, are piling on the pounds.

Let's face it: most vehicles sold in America are obese. Today’s average car is portlier than a binge-eating sumo, while your standard issue full-size SUV weighs as much as a fully-grown hippopotamus. In 1987, the U.S. fleet average was 3220 lbs. In 2006, the average US vehicle tips the scales at a scarcely credible 4142 lbs. In a time of high gas prices, when we should be building cars that eke out the last mpg, this makes no sense at all. Or does it?

In the intervening years, federally mandated safety equipment and the commercial importance of crash test ratings have added weight to America’s fleet. But, in 2001 (the last year where I could find applicable data), safety equipment accounted for only 125 lbs. of an average vehicle’s total weight. It’s risen since then, but even if you double this figure it’s still a far cry from the over 900 lbs. increase over the past 19 years.

Clearly, manufacturers have met passive safety requirements without resorting to simple fortification. In fact, the weight gain comes in spite of an upsurge in lighter-weight automotive materials. Cars were once built almost entirely out of ferrous materials; today’s vehicles are constructed with less than 65% steel. The remainder consists of materials like plastic, aluminum, magnesium, titanium and balsa wood. Yet vehicles keep adding poundage.

Of course, it takes energy to move all this mass around. While most manufacturers meet federal Corporate Average Fuel Economy standards (save fine-paying miscreants like BMW), almost every single carmaker has shown a lamentable decrease in overall fuel economy during the past three years. As weight goes up, so does fuel consumption. It doesn’t take a genius to figure that one out, so why can’t carmakers cut the crap? Why aren’t they doing more to decrease the weight of their products across the board?

The bottom line is the bottom line. The auto companies are in business to make money (Ford’s and GM’s recent performances notwithstanding). Large SUV’s and pickups are far more profitable than passenger cars. Automakers have been doing everything they can to push as many of these money-makers into the hands of the consumer as possible. Until recently, the car-buying public rushed to them like bomb shelters in Baghdad, oblivious to their appetite for Jurassic juice. As car makers sold entire flotillas of big-ass behemoths, they’ve driven the average weight stats higher and the fuel economy averages lower.

Consumers who wouldn’t even think of buying an SUV or pickup truck are also contributing to the trend toward excess automotive avoirdupois. Once upon a time, electric windows, remote alarms and power door locks were a luxury. Just ten years ago, sunroofs, automatic climate control and sat nav systems were restricted to luxury cars. Today, all these toys are available in the most basic econobox, and a “necessity” in any car with upmarket pretensions. Extra goodies, extra weight. No wonder the two-door Honda Civic has porked-up nearly 400 pounds over the past 10 years.

So what’s the solution to this weighty problem? U.S. car makers must get serious about slimming down. Earlier this summer, several automakers established weight targets for parts and asked suppliers to redesign them accordingly. That’s an excellent step in the right direction, but they need to go further. Every manufacturer redesigning their products– from economy cars to mid-size sedans to full-size SUV’s– needs to make weight loss a top priority. They should trim vehicle weight by at least 20% while maintaining utility. And why not? In 1977, GM downsized their entire full-sized passenger car lineup and watched sales go up. It’s time for an encore.

The American Plastics Council estimates every 10 percent reduction in weight delivers a seven percent increase in fuel efficiency. If the 5342 lbs. Chevrolet Tahoe lost 20% of its fat, urban mpg would rise from 16 to 18.24 mpg. But fuel economy isn’t the only benefit. Can you image thrashing a Pontiac Solstice that weighed 500 lbs. less? Or how much more tossable a Honda Civic hatchback would be with today’s power at ‘96’s weight? For pistonheads, “road hugging weight” is as undesirable today as it was in the 70’s. No matter how you look at it, it’s time for all U.S. vehicles to go on a diet.

    A psychologist friend of mine believes that all the safety equipment in todays' cars makes them LESS SAFE. His reasoning is that drivers will take many more chances, chances they wouldn't normally take, because they put too much faith in all the safety systems in a car. He says that if you want to see safer driving, instead of putting in airbags in the steering wheel, they should put a sword facing the driver there.

    at 6'3" and well into the deepside of 200 lbs (football player). . .i have managed to fit myself into a lotus exige. . .it was sure a challenge, but not impossible. . . you can fit into a civic!

  • NotMyCircusNotMyMonkeys dudes off the rails on drugs and full of hate and retribution. so is musky.
  • Big Al from Oz Musk and Trump are of the same ilk, except Musk's IQ is a damn site higher than Trumps. Musk like Trump is only into himself. Musk doesn't care about Trump only Musk. Musk sees more dollars if Trump wins.Hey, I'm Big Al again!3
  • Rover Sig We have a car with two fake exhausts in the bumper, but a large shiny muffler visible hanging down on one side, not aligned with the fake exhaust exits. Horrendous. I had to paint the shiny muffler with high-temp black paint to make it less visible. Exhaust pipes were meant to be round and hang below the bumper, and they can be made quiet or loud as the engineers like. But fake exhausts rank down there with fake intake vents on the side of that old Buick.
  • EBFlex Of course it does. What a silly question
  • Buickman Elon is a phony.
