I know nothing about cng vehicles. I have a honda accord that gets about 25 mpg. If a similar car was switched to cng what size tank would it have and how far would it go on a tank? how many cubic feet of gas does it take to equal a gallon of gas? and what would the equivalant of a gallon of gas at 2.40 cents be for cng at todays prices. Sorry for all the questions but I don't even know anyone that has any experience with cng cars.

I have the same questions tonight?
Good luck!
I think it is mostly for 18 wheelers etc. that they're talking about it being the biggest benefit because hybrids are already here.
JA, you are correct that CNG has historically been targeted at transit buses and heavy duty trucks but it can also be used in passenger vehicles. LNG may be a better long term fit for large trucks and buses because of the performance level and longer cruising range.
Even if CNG should cost the same as gasoline, it would be nice to know some terrorist supporting country wasn't benefiting from your fuel purchase!
Bob, the Honda GX CNG holds the equivalent of 8.03 gallons of gasoline or ~ one million Btu's. The natural gas volume is about 975 standard cubic feet but only 3.99 actual cubic feet of gas at the 3600 psi storage tank pressure. A typical CNG storage tank would be about one foot in diameter and four feet long.

It is difficult to estimate the CNG retail price but it could currently be as low as $1.00 per gasoline gallon equivalent. Longer term prices will likely be closer to $2.00 per GGE.
There are several fueling stations in Dallas. The posted online price is $1.95 per gasoline gallon equivalent.
Right now the max driving radius for 18 wheelers is about 300 miles on CNG. The fuel tanks are heavy and eats into the hauling capacity. CNG works great for buses, trash trucks, etc.. that don't need to travel long distances. Hopefully the storage tank technology will progress soon.

Cars can run dual systems, CNG and gasoline with a conversion kit.
Thanks for the info. I wonder if they will come up with a small affordable compressor that you could fill up at home with. Not that it would do me any good. I'm all electric because there is no gas service out here. Kind of ironic that I can hear the gas roaring from the well they just drilled about 1000' from my house but no gas for my house. Oh well, eventually it will help me pay the electric bill.
Honda sells a compressor for your home. the original manufacture went belly up, but has been aquired by a new company. Its what T. Boone uses.

Fuel Systems Solutions Completes Acquisition of Certain FuelMaker Assets and Purchase Orders
SANTA ANA, Calif., May 28, 2009 (GLOBE NEWSWIRE) -- Fuel Systems Solutions, Inc.
