Chuck, it seems that even the engineering is already in place. It also seems to me that natrual gas vehicles shouldn't be more expensive to build than gas cars. Put in some infrastructure and this might take off.

GTOlover,

That may be the same one that I saw written up many years back. I don't imagine that there are that nany CNG fueld performance vehicles around.

Just think of the interesting possibilities, starting with boost pressure from a venturi fed by a scuba air bottle, which has been done a few times, and then adding a high pressure fuel feed from the 300+PSI propane tank. The controller to maintain the right mix would be a challenge, but for a singel application in a quater mile car it should be quite achievable. Just hope that the rest of the vehicle could hold itself togather for the run.  A green four second car, what a thing to show off. Plus, it would probably be impressive to hear. And the spark plugs may be good for more than one run.

Agree with you William K. Not only are people stupid, but apathetic to safety. How many smoke while fueling their car? But let's assume that CNG refueling goes the way of the Oregon law (you cannot fuel your own car at the gas station). Have you noticed how people maintain their vehicles? Most people just trade-in their car after it gets older, but then the people that buy the used car drive it like it is new and never seem to properly maintain the older car. I can only imagine what bent, corroded, or leaking CNG fuel lines would be like when the guy in front of you flicks his cigarette out the window!

Aside from going of topic, I did see an incredible  1966 GTO tri-power that was converted to a CNG vehicle. It boasted very good performance and it looked stunning and stealthy.

Natural gas as a fuel source for passenger cars suffers from both a small number of refueling stations and a very real increased complexity of the refueling process. If you have ever watched people at the self-serve pumps it would be clear to you that a lot of folks just simply would be unable to "make the connection". The number of totally incompetent people around seems to be growing daily, and even worse, we are being forced to accomodate them by having many activities dumbed down so that even stupid people can do them safely. 

And make no mistake about my meaning: I mean stupid, which is about the opposite of retarded. Retarded people are amost always giving their very best effort and really trying, while stupid people put forth the minimum effort and really don't try because usually they don't care. And stupid is a choice that they make, not a condition that they are born with.

Aside from that wandering from the topic of CNG and LP fueled cars, the performance has not been as good as gas engine cars, probably because the conversions have not been as complete as would be needed for better performance. But I think that back in the seventies I read about a CNG fueled dragster. I guess that it never did well enough to make the headlines, though. But the initial performance postings were impresive.

You may be right about it taking long for natural gas vehicles to get wide consumer acceptance, Jhankwitz. But in some ways, it seems they would be less expensive than EVs or hybrids to produce. And if the pumps were widely available, I would think the low cost would make them attractive to consumers.

Chuck, do you know why it's been slow to see natural gas powered cars? Seems like natural gas has made huge strides with city busses. Why not cars, especially given the low cost of natural gas?

I agree, Rob. Infrastructure is key here. The nice thing about CNG vehicles is theyy're not waiting on science. The science is there, what remains is engineering and infrastructure.

The Impala was quite a hit when it came out, at least among Chev lovers like me, and therefore I was very excited at the prospect of a new Impala model that runs on bio-fuel. However, the manufacturers could have done more on the natural gas coverage of they really want to be at the top of this field. The 150 miles roof limits it to more of a day to day town vehicle and not a great option for long distance rides.

H2 is a better option

If you are going to have to build an infrastructure, why not make in based on hydrogen. That is the better option for long term usage. CNG can be converted to H2 and forget these cars.

Good point, MrDon. I believe there would be wide acceptance of natural gas powered vehicles if the refilling stations were convenient. That may be a while off. there may not be enough time to set up the infrastructure before the CAFE standards go into affect, so this may not help automakers reach their mandated goal.
