About LPG Vehicles

What is LPG vehicle?

The LPG vehicle produces little particulate matter and nitrogen oxides, marking its eco-friendly feature, and its low fuel cost also makes it economical. The vehicle boasts excellent quietness due to its low noise and vibration, while its safety has been widely proven through various safety certifications for its safety devices and components and crash tests

Cleanness of LPG vehicles

Due to fuel cleanness, the LPG vehicle emits very little particulate matter (PM10) which causes various respiratory diseases and lung cancer, and it also emits significantly less amount of nitrogen oxides (NOx), which serve as the main cause of generation of secondary particulate matter.
Comparing the nitrogen oxide emissions of vehicles by fuel type, the average nitrogen oxide emissions of LPG vehicles are significantly lower than those of other types. In outdoor road tests similar to the actual driving environment, in particular, LPG vehicles emitted only 1/93 of the nitrogen oxides emitted by diesel vehicles.

If the combined emissions of harmful substances, such as greenhouse gases, are compared in addition to particulate matter and nitrogen oxides, the cost of environmental damage caused by LPG is only KRW 246 per liter, which demonstrates the most eco-friendly feature among internal-combustion engine vehicles.

Economic benefits of LPG vehicles

The price of LPG is about 55-60% of the price gasoline, and even when considering the fuel mileage of LPG vehicles, it is still at 65-70% of the price of gasoline. Comparing When comparing the mileage between LPG and gasoline vehicles per same fuel cost (KRW 100,000), the gasoline vehicles and LPG vehicles travel 695km and 896km, respectively, so the latter saving could save at least 23%.

According to the government's Traffic Tax Act and the Special Consumption Tax Act, the relative prices of gasoline, diesel and LPG are 100:85:50. It was established in consideration of the social costs and gas mileage of oil and the relative costs of different oil types overseas for the eco-friendly distribution of vehicles in the transportation sector.
