How Our Waists Are Wasting Gas

Men's Health Obesity Infographic, http://news.menshealth.com/cost-of-obesity/2012/05/09/


Weight loss is a complicated system. Many believe that at its core, the science of gaining or shedding pounds boils down to calories in versus calories out. But when you start adding in other factors, such as the amount of exercise a person gets, the amount of carbs they're eating, or if they have a thyroid problem, things can get complicated.

Now, as far as cars are concerned, gaining weight is a different (and much simpler) matter entirely. The heavier the car, the more energy it takes to use. This is true for both the weight of the car and the driver inside!  And we're apparently burning more gas than ever. Engineer Sheldon Jacobson of the University of Illinois claims that "Growing obesity rates increase fuel consumption."

It isn't terribly difficult to see why Americans are burning an extra billion gallons of gas each year, compared to twenty or thirty years ago. The added stress of additional weight requires more fuel to be burned. Take the price of gas ($3-4) and you can quickly multiply the cost we incur annually. To make matters even more complicated, many drivers are still on the road with large gas guzzling vehicles, which become even less fuel efficient as passengers become larger.

On the bright side, Toyota has been leading the pack as far as car makers go, introducing new vehicles that have the best mileage on the market, with the intent of getting other automakers to focus more on efficiency than size or power. While that won't do anything to enforce healthier eating, perhaps we simply need to take a page from their home country. The Japanese government is involved in enforcing a weight loss program for citizens that requires men and women to not let their waistlines grow larger than 34 inches. If they don't maintain their health, their employers can be fined, which probably doesn't bode too well for the future career of that particular employee.

When you think of it that way, Japanese citizens in Toyota cars get to enjoy the full listed MPG of a car. Back in America, we have to ask ourselves- what can we do to combat obesity so that we don't succumb to this massive waste of gasoline? I've read stories on how car seats and other public transportation seats are being outfitted with slightly larger seats as newer models have come out over the years, in order to adjust to the growing size of the overall American population. You need not look further than the infographic above for proof! In my eye, that's taking a step backward by accepting our rising obesity, rather than trying to prevent it.

How do you feel about this issue? As we focus on making cars more efficient, should we also be concerned on keeping ourselves healthy? Or should automakers and companies continue to cater to growing waistlines by widening seats and employing other tactics?

Where's My Spare? The mystery of missing tires


Teenagers changing a flat tire

Flat tire? Not as many cars are coming with a spare nowadays.

Not too long ago, the Department of Transportation and the Environmental Protection Agency established some new rules regarding fuel economy, and set goals they wanted car makers to hit. According to their regulations, the average fuel economy of a car must reach 34.1 miles per gallon by 2016, and 54.5 miles per gallon by 2025.

Other than using hybrid or electric technology in a vehicle, what's one other easy way to make a car more efficient? If you guessed shedding extra weight, you'd be right! Because of this, auto makers are finding every way possible to make their vehicles lighter - using lightweight steel and carbon fiber, and in some cases, getting rid of the spare tire that many of us have come to expect in the trunks of our cars. The idea of dropping pounds is relatively new, too. According to Christopher Knittel of the Institute of Transportation Studies at the University of California, Davis, "From 1980 to 2004, the average fuel economy of the U.S. new passenger automobile increased by less than 6.5 percent. During this time, the average horsepower of new passenger cars increased by 80 percent, while the average curb weight increased by 12 percent."

Removing that spare tire can lower the weight of a car by up to 40 pounds, slightly aiding the car in reaching MPG goals set by the manufacturer. When I drove my old vehicle around, it didn't come with a full size spare. Rather, it had a "donut", which is a smaller tire designed to only travel short distances (until it can get replaced at a repair center). I was ok with this, because my car had more trunk space as a result.
However, AAA is reporting that the days of donut spares may be quickly coming to an end as well! In fact, some cars might only come with a sealant kit, or "run flat" tires, specially designed tires that can be driven on for short distances after a puncture has occurred, so that a driver can safely get to a repair center.
So what Toyota vehicles have ditched the spare?
  • Sienna XLE (run flats)
  • Rav 4 Sport (run flats) 
  • Scion iQ (inflator/sealant kit) 
Fortunately, all newly purchased or leased Toyota vehicles come with 2 years of ToyotaCare service, free (and if from us, you also get AutoAwards coverage!) So whether you blow a tire, need your battery jump started, or a tow, you'll have 24 hour roadside assistance available.

Would you prefer a spare tire in your car for peace of mind, or do you like the newer alternatives, such as the sealant kit or the run-flat tires being equipped in certain vehicles? Do you think 40 pounds makes a noticeable difference in improving fuel economy? Leave a comment or share your thoughts with us on Twitter @LouFuszToyota !
