GM plans to sell pickup trucks that can transition between regular gas and natural gas. The company says drivers can potentially save thousands of dollars a year in fuel costs by using the compressed natural gas option - available at about 1K fueling stations in the U.S.

    If they can produce a 1 ton truck with the same power and torque my Duramax/Allison diesel puts out, I'd switch in a second. I read a filling station in your home would take over night to fill a 30 gallon tank, that would need to be greatly improved for regular fill ups.

    horse power stays the same, mpg stays the same, cost of natural gas is 1/2 that of gasoline. major trucking companies have fleets now that can load in less than an hour. estimates are that you can save 12k over 8 years with natural gas and your engine wear and tear will be half that of regular gas. ;-)

     

    ps> a natural gas tank should push a car go over 500 miles.

    Yeah few things:

     

    1) The home refueling systems are typically low powered compressors that take a whole night to refill your vehicle, and cost under $4k.

     

    2) The commercial refill stations do it in about the same time it takes to fill a vehicle with regular gas.

     

    3) Because of the lack of particles and the cleaner combustion the engines last longer. But, you incur the add'l cost of eventual replacement of the tank cylinder (it has an end of life date)

     

    4) Kits are available to add CNG subsystem to any existing vehicle, the most expensive part being the tank.

    kmi: Why does the tank have an end of life? I would think it would last as long as the vehicle.

    They are like scuba diving tanks or any other tank that holds contents under pressure. My layman's grasp of the subject suggests that because of the stresses of pressurization/de-pres... incurred by filling and consuming the tank with gas it loses its structural integrity over time, whereas a gas tank for example holding gasoline holds it at atmospheric pressure.

     

    Here is a link to a website that sells tanks, for example, and prices them by how close the end of life date is to the date of purchase.

    I installed a gas line in the garage of house I was having built, in anticipation of NG vehicles. That was in 2001.

    could the dummies at GM finally have a clue? now if they could learn how to market their cars and trucks differently, they might just be successful. same old advertising model that hasn't worked in 20 years. i got 8th grade students that can put together better advertising programs than Ford and GM. i don't think GM can wait long enough for the old guard to finally die off and get some new blood in there.

    Should appeal to small fleet owners who can install their own filling station. Waiting for our school bus fleets to start transitioning. Spend the money on books instead of fuel.

    I expect this to impact farm areas - possible that Co-ops increase fueling. Farm driving habits are much different than commuters.

    We will all be driving natural gas vehicles by 2020. The government incentives will be extraordinary.

    As soon as they make them safe enough to survive an accident, we're on natural gas for everything..............
