The mileage of a car is always the most sought after details by buyers while buying a car. Indians are known to be very particular about fuel efficiency
and running costs.
The car industry has seen a complete revolution compared to early 90’s. During 90’s, there were fewer cars on road and Maruti was ruling the car sector with small car like M800. The car continues to remain one of the most fuel efficient cars of all time.
But recently when fuel prices went skyrocketing and cars were brought under intense scrutiny with respect to mileage, the companies have been highlighting fuel efficiency of their cars.
The Indian buyers still purchase cars with a pinch of doubt on fuel efficiency claims. Earlier, there has been little study on ambience pollution levels and car emissions in India. But for the first time the Centre for Science and Environment has released a report based on study conducted by Automotive Research Association of India. The report states that cars and two-wheelers contribute the maximum carbon dioxide in Delhi, which is the highest polluted city in India. The biggest revelation is that details about oil consumption, certified fuel economy data in km/liter of each make and model of car is kept secret.
In a study conducted on vehicles manufactured in 1991. The emission levels were found to be much lower compared to new cars
. Petrol cars manufactured post 2000 with engine size more than 1.4 liter reported CO2 emission of 143gm/km. But in same model of cars post 2005, the CO2 emissions were higher by 173gm/km. Further the fuel economy had dropped from 16 km/litre to 13 km/litre.
The study conducted on diesel cars was also not encouraging. The diesel cars with engine size less than 1.6 liter manufactured during 1996-2000 emitted 129gm/km, whereas the car manufactured post 2005 has higher emission levels of 149gm/km. Further the mileage has dropped from 20 km per liter to 18 km per liter.
have the highest CO2 emission levels. The SUV models with engine size less than 3 liter and manufactured between the periods of 1996-2000 had recorded CO2 emission of 189gm/km. Emission in the SUVs manufactured post 2000 had increased drastically to 229 gm/km and had further increased to 256gm/km in the models manufactured after 2005. The fuel economy has dropped to14 km/liter in 1996-2000 to 10 km/liter in post 2005 models. An SUV emits green houses gases equal to two small cars.
It is shocking to note that new cars are less fuel efficient than older cars. It is interesting to note that older cars, which are criticised severely as fuel guzzler were actually more fuel efficient and emitted less green houses gases. May be the car industry gets the answer in the coming year when the fuel crisis will be high and the car buyers look for more fuel efficient cars.
