As the name suggests, LPG cars are fueled by liquefied petroleum gas (LPG) and CNG is powered by compressed natural gas. The CO emission of gas vehicles is more than 90 percent less than the gasoline car, the hydrocarbon emission reduction is more than 70 percent, and the nitrogen and oxygen emission reduction is more than 35 percent, which is the current relatively practical low emission vehicle. Moneyfacts says the average instant access savings rate is only 0.07 percentage points higher. Sometimes when we're driving, we suddenly smell gasoline in the car, and then we get nervous.
