Fuel index: Complete a lie


Chỉ số tiết kiệm nhiên liệu: Toàn là dối trá- The case related ads equivocal Hyundai Elantra has fanned doubts in public opinion about the fuel economy of the car manufacturers.Great writer Mark Twain once wrote that there are "three kinds of lie: lies, damned liar and statistics." He's absolutely right when saying for fuel economy indicator that the carmaker announced.
The "equivocal fight each black child" in the Hyundai ad on the fuel consumption of the last time Elantra has fueled the fire of discontent when on the day to receive the information lies from the manufacturer. Hyundai, was sued for deliberately misleading about the numbers, but the other car manufacturers? They are in cleaner? The fact is Paul A. Eisenstein, editor TheDetroitBureau.com exposed: no car company does not lie on the fuel consumption.
The fact that any riders all know: the actual fuel consumption figures are different from the numbers that the manufacturer announced. Manufacturers are wise to add a sentence to their advertising "vehicle fuel consumption can be the difference". Yes, clear differences instead. You drive less, pedal irregular, heavy transport, the way he goes bad quality, doped petrol he used poor quality .... So how requires consumption with standard manufacturer ? That there is nothing to discuss.
So it's always been, buy a little car reviews, car buyers in Vietnam, the more gentle comments. Well, then chuckled, "first charge century, post-charge".
So car makers are spoiled storm. New opinion fell back, his ever working full ad on more fuel-efficient vehicles, but did not know that was pierced nose.
We usually based on fuel consumption indicators that EPA U.S. Environmental Protection Committee for a new car launch. The agency used the CAFE average fuel consumption standard to evaluate each new vehicle with three criteria, fuel consumption on urban roads, highways and sugar mixture. After the EPA numbers, they will be included on the Monroney sticker pasted in the window glass for customer reference.
In fact, few know that the EPA has only 20 staff responsible for test vehicles, and only about 15% of the new car market launch is tested in real conditions. The rest, they believe in the numbers that the manufacturer made.
For about 15%, equivalent to more than 200 "fortunate" test, it is up to you to use force design and computer-controlled equipment to simulate parameters such as friction with the road, wind resistance direct ... When driving, the EPA staff are trained in accordance with the instructions of the computer in order to ensure a speed, the most reasonable acceleration and braking.
Initial data also have to tweak as the use of air conditioning and other factors.
Adapting to the rapid changes to technology today must also be taken into account. For example, a growing number of vehicles driven AWD, or the birth of a new type of transmission, such as hybrids, electric vehicles. EPA must constantly update and change can make accurate measurement.
The average fuel consumption figures published by the new cars launched in June in the U.S. is 29 mpg, or 8.11 L/100 km, while the figure that the EPA is 23.6 mpg, or about 10L / 100 km. So easy to see with the EPA testing, the average differ to nearly 2L/100 km from manufacturers give figures.
Returning to the data "super savings" of Elantra, with 28 mpg (8.4 L/100 km) in the city, 40 mpg (5.88 L/100 km) highway, published fuel consumption 5 , 9L/100 km apparent ambiguity here. Hyundai representatives acknowledged "we also want to promote the best approximate the actual numbers that customers will experience, but to do so we will be at a disadvantage in the competition."
Both market so, if Hyundai do otherwise, it is clear they will dig holes to bury ourselves.
General rules, only consumers suffer if they too believe in the advertising and publication of the manufacturer.
