Limited Cost-Effectiveness of Gas Powered Cars
The decision to run a car using natural gas, instead of petrol or diesel, is often made in the hope of reducing fuel costs. However, a German car magazine claims that motorists need to cover a minimum of 13,000 kilometres per year in order to make the changeover financially worthwhile.
Compressed Natural Gas (CNG) and Liquefied Petroleum Gas (LPG) are the two varieties of gas available. Most often, CNG is more costly than LPG, although it has the benefit of burning with greater efficiency and thereby proves more economical in the long run.
A number of cars can be modified to run on LPG. In contrast, most cars fuelled by CNG gas are created from new to operate on this type of gas. Cars that run on CNG are more expensive to purchase than their counterparts that are fuelled by petrol or diesel.
German motoring magazine, Auto Strassenverkehr, claims that in some instances, 150,000 kilometres would need to be travelled annually in a car fuelled by gas to reconcile the financial outlay.
