From what I’ve heard it is difficult to start and get a CNG vehicle to run smoothly until it has a chance to warm up in near freezing weather. It can be solved by an engine heater, parking inside a garage or avoiding the situation by having a dual use engine.
That is good to know, because we have toyed with the idea of getting a Honda Civic CNG car for my husband’s commuter car, even though it costs so much more.
I doubt we will now, since we do often have cold days in the winter. Probably stick with getting a Subaru Impreza. However, with the way the economy is, we will stick with his Ford “Barge” for a long time.
