CNG and LPG cars are indeed very tempting, if you look at the potential cost savings. We bring you a guide to the alternative fuel cars in India
LPG and CNG powered cars are the need of the hour mainly because of ever-increasing petrol and diesel prices and vehicle pollution levels. Emissions coming out of an LPG fueled engine has 10% lesser Co2 content when compared with a petrol engine. Similarly, CNG and LPG-driven vehicles emit lead free, less harmful elements into the atmosphere. Besides, the operational cost of cars driven by LPG and CNG is a mouth watering 30%-70% lesser compared to petrol or diesel. However, due to lack of infrastructure, except for Delhi and Mumbai, others have to adjust with the scarce availability of LPG and CNG and plan beforehand in case they wish to save money by buying LPG/CNG cars.
How much difference?
When compared to a petrol car, the cost of a similar LPG car is roughly Rs. 22,000 more and the cost of similar CNG car is roughly Rs. 55,000 more. However, you can recover the initial amount by running the car more in LPG/CNG than in petrol. Since CNG price is lower than LPG, the time of cost recovery is faster. In either case, it would take at least a year and a half to recover the initial cost.
LPG vs CNG
We are very well aware about LPG’s lower ignition temperature and heavier density. Hence, among the two alternate fuels, LPG kits must be double checked periodically so as to ensure no leakages. Now, since manufactures themselves provide us the LPG kits, we need not worry much. On the other hand, CNG is cleaner than petrol as it lacks lead compounds and is colorless, odorless, non-toxic and non-carcinogenic. Even in case of leakage in CNG cylinder, unless the leaked gas comes into contact with fire, there is a low possibility of accidents. It must also be noted that the usage of domestic LPG in cars is illegal and must be forbidden because it has a different composition as against Auto Gas and may damage the vehicle parts besides being unsafe.
Performance
Regarding the performance of LPG and CNG in cars, in both the cases, manufacturers themselves have given data regarding the power and torque of their LPG/CNG models which are lower by 1-10 bhp of power and 5-20 Nm of torque than the corresponding power and torque figures of petrol models. The driving experiences of LPG/CNG car owners confirm the fact that the alternate fuels do cause a dent in the vehicles pick-up and power delivery. Well, that is just a small compromise we have to make in order to save money spent on fuel bills.
Pros & Cons
While diesel is considered as the cheaper fuel that offers lower running costs than petrol, LPG, and especially CNG can drastically lower the running costs of your car. Since LPG and CNG are cleaner fuels, the life of lubricants increases, allowing us to save some more money. However, care must be taken to clean the air filter frequently in case of LPG cars in order to ensure maximum fuel efficiency. A well maintained LPG/CNG car gets a better resale value.
LPG and CNG are not as easily available in all gas stations and hence, we have to research the availability of LPG/CNG filling stations before purchasing the greener vehicles. In the worst case, since the cars come with petrol tanks, we can still manage to save fuel wisely by filling the LPG/CNG tanks wherever available. Regarding safety, a decade ago there were frequent fire accidents due to unapproved less safer LPG/CNG conversion kits. But now, as manufacturers themselves offer factory fitted kits with warranty, people can ensure that they are buying safe LPG/CNG cars.
If you can stretch your budget, and have enough of CNG/LPG filling stations, do consider buying the ‘greener’ cars for a second time. Due to lack of widespread infrastructure for LPG/CNG filling stations, customers may have to wait for almost double or triple the time in refilling LPG or CNG as against refilling petrol or diesel during peak hours.
Alternate Fuel Cars in India
In this article we will have a brief discussion on all the LPG and CNG cars (with factory fitted kits) available in the country.
