Fuel Efficiency

In Brazil, many cars run on gas.

Big whoop! Most of the car in the U.S. and everywhere else are run on gas.

No, not gasoline. Natural gas.

After a little research, I discovered that there are a handful of cars in the U.S. that run on natural gas, but not many.

Of course, natural gas is better for the environment. But here is how it works in Brazil:

In this case, the gas tank is in the bed of the truck. Often you will see the tank at the back underneath of the car.

I’m CERTAIN someone engineered a way to make sure that if a natural-gas operating car were to be rear-ended, it would not result in a mind-blowing explosion.

  1. I saw a lot of natural gas buses in California, but I’ve never seen them here. But they also use ethanol a lot here. I don’t want a natural gas vehicle. Scary!

    Is that what they call “sarcasm”? 🙂

    Anyway, it’s a good question. I had a quick look around and although I couldn’t find a lot of details, it seems Inmetro (similar to NIST in the US) does have a handle on it:

    I’ve seen taxis here that run on natural gas.

  4. Reminded me of this bad boy:
    In the end it turned that no evidence was found against the vehicle.
    Personally though I think it better to risk an explosion than to drive, and subject others to seeing this:
    I bet you that, sooner or later, some auto exec genius is going to suggest updating and then bringing that eyesore back.

    Dear B.A.B,

    Cars running on Natural Gas nowadays are very safe in Brazil, the government decided to regulate this type of fuel because many people were making “improvised” adaptations on their own, this was back in the 80’s when only Taxis were authorized to run on natural Gas.
    When the government regulated and made it legal for all cars, Ford, Volkswagen, Fiat and GM started making cars with Gas tanks from the factory, they are very safe and don’t cause explosions. 🙂
    By the way, most buses in New England, Boston and Rhode Island, already run on Natural Gas, also school buses, Snow Plows and City and state trucks and Trash Collection companies. 😉
