On the commercial vehicle side, Italy counts some 1,200 CNG trucks, mainly operating in garbage collection services, and 2,300 urban buses.
The number of natural gas vehicles has reached this significant level over the last 30 years as a result of a very active retrofit conversion industry and the availability of more new car models with ex-factory CNG options is pushing the growth of the NGV market share further.
Regarding economic reasons, the savings in fuel costs per kilometer for a medium duty car running on natural gas is about 60% compared with an equivalent gasoline engine and 33% compared with a diesel version.
