Honda increased production in '12 of cng as they rolled them out to a total of 38 states rather than just the 4 states previously. Demand was low and a lot of them sat on the dealers lots. I got $7K off sticker and that made it the same price as the Civic EX-L. Civic cng is auto trans only, 5 speed.
I live in PA and as you may have heard the shale gas boom has started. I will not go it to whole fracking debate but will say that PA and WV will have a network of cng stations within the next couple of years. There are about 4 within 15-25 miles of me. Some trucking companies are converting to cng and a new station will open near me in a couple of months. CNG is measured in gasoline gallon equivalent (gge) and right now it is $2 a gge. Mileage is also measured the same so you can compare directly between gasoline and cng. I get between 38-40 mpg. The tank is 8 gge’s and I get about 300 miles per tank.
Since cng has a much lower energy density, but is about 120 octane, the 1.8L engine only gives 110 hp. So it is slower. It is good enough for me. Sure if you are a lead foot and want to drag race light to light it is a little slow. But the Civic hybrid is also about 110 hp. I don’t have all those batteries weighing it down and the mileage is not too much less.
I still don’t understand why this can’t take hold. We would end our dependence on foreign oil and create jobs here in the US. As technology increases you will see large cng tanks and more hp from the engines. They are also trying to develop a home refueling station that would cost $500 instead of $3K. But all we really need is more cng stations. It is slowly coming, at least around here.
So, that is my take on it. Hope this isn’t too long a post.
