I believe that's the CNG option on the cav's for fleet and government use. Converts the car to run on natural gas, it was an option from GM. Should provide better fuel economy (cost wise, not sure about actual km's per tank) at a slight cost to performance. But finding a fueling station won't always be easy. Most people go with propane due to the fact that its easier to find, provides similar benifits being clean burning and available at a better price than gasoline and allows the use of a smaller tank, which as you can see in this car is very large.

i would not want a natural gas/propane powered car
I HATED filling those up when i worked at a Gas station
that is a CNG Cav. TONS of them here in AZ.

Just dont get rear ended.............
3400 SWAP DONE. 187WHP 212TQ (14.2 @100MPH NA) 240WHP 310TQ (N2O)
cng Cavys, that's a whole different thing from E85 right or is it similar to the flex fuel cars.
I have seen CNG Cavaliers with the Eco but never with that older style of fuel delivery. The CNG Eco I saw had a second set of injectors just for the CNG.
i thought they discontinued the Cng cavys in 2002 the same year they put the eco in.
seems like there is always one on ebay.... i remember the "fog light" switch is used to switch between fuels.

totally different
CNG would be GAS in the normal gas tank and then the propane/natural gas in the other tank they essentially have 2 fuel systems
my tahoe is flex fuel that just means it can run on E85 or regular unleaded.........both fuel goes in the same fuel tank only 1 fuel system..........
Viper you said the cng cavys have 2 fuel systems, how would you gas one of those up you could get the regular gas at a gas station but where would you get the natural gas from. Would you just empty a can of propane into the gas tank along with the regular gas or what that would probably cause a major explosion LOL.
Quik i'm sure it is, but again how do you fill it up someone said it had 2 fuel systems the cng cavys that is the regular gas in one and the natural gas in the same tank or what?
You still have a regular fuel tank in the same location as every other J car.

If you get rear ended hard enough to rupture the tank you would probably be dead anyways. I rather suspect teh CNG system would be able to take more of an impact than would be survivable by a person anyways, regardless of location.
I worked at a gas station in highschool and we had propane and a automobile propane station they are not that hard to find you just have to be carefull and look for them

this is the place you fill it

fixed this for you i understood but was confusing Bill.
bill- i hope this answered your original question. i just was wanting to know if there is any benefits besides that it burns cleaner (better for the environment) but i think cost out weighs benefits.
i never knew about any of this.... interesting
ive got the GM manual for the bi-fuel CNG cavs. if you want to see it jr, just let me know
and this sort of car would be great for lots of people around here who have mineral rights and free natural gas. the pump, on the other hand, would be kind of expensive.
surrprize no one has relocated the reglar gas tank filler there yet, buy that little door
JBO since July 30, 2001
^^ was thinking about it. but other side be bad to drip gas on the exhaust.
ive been looking for the PN for that door and have had no luck at all. ive even emailed a few owners and joined a CNG car forum. still no luck
Couldn't you make one? Just have a small hinge and a high powered magnet or something like that.
a small percentage of eco's are bi-fuel (e85). I believe they're VIN "6" instead of "F". I'd kill to have a flexfuel ecotec.

A more accurate observation has never been typed. These should be the starting points before any serious performance modification. What's the point of making a serious performer if you can't control it's power?
