..........................
"Gasoline cars usually consume 6 or 7 liters of oil in 100 kilometers. At the current oil price, that will cost about 30 to 40 yuan. However, if the car is fueled by natural gas, it only will cost 15 to 16 yuan for 100 kilometers."
Three hundred newly designed cleaning vehicles will also be on display. They will be used to for the Beijing Olympics.
