The fact that Hyundai/Kia was severely fined by the US Environmental Protection Agency (EPA) for falsely reporting fuel economy values ​​did not seem to alert all car companies. Recently, the EPA asked MINI to reduce the fuel economy of its 2014 Cooper model.
The EPA requires the 2014 MINI Cooper to reduce the fuel economy value of the 1.5L Cooper three-door version and the 2.0L CooperS three-door version of the two models, there are varying degrees of fuel consumption exaggeration. According to EPA tests, the data reported by automakers has one or two mpg exaggerations in each test, but the most serious is the high-speed fuel consumption data of the Cooper three-door version. The EPA determined that its fuel consumption was falsely reported at 4mpg, and the actual fuel consumption was 34mpg (about 6.9L/100km), but MINI claims that its fuel consumption can reach 38mpg (about 6.2L/100km).
“The fuel economy value is a very important indicator for consumers to buy a new car,†said Christopher Grundler, head of the EPA Transportation and Air Quality Office. “To provide consumers with the most accurate, reliable and repeatable test fuel economy Value, we are constantly strengthening supervision to promote car manufacturers to compete fairly on this indicator."
US fuel economy value increased by 0.5mpg in 2013
Recently, the EPA has calculated the fuel economy value of new cars sold in the United States in 2013. The data shows that the fuel economy of the average bicycle in 2013 was 24.1 mpg (about 9.8 L/100 km), which was 0.5 mpg higher than that in 2012. At the same time, this is also the best level of history measured by the EPA.
According to the EPA's goal, before 2025, when the electric vehicle accounted for 10% of all models, the average bicycle fuel economy should reach 40mpg (about 5.9L/100km). According to US President Barack Obama’s “instructions,†the average bicycle fuel economy of automakers in 2025 should reach 54.5 mpg (about 4.3 L/100 km).
Although the increase of 0.5mpg seems to be far from the goal of 2025, EPA executive Gina McCarthy believes that the 2014 data shows that new technologies are beginning to show their power. "2025 is a time node for the adoption of this new round of technology," McCarthy said. At the same time, she said that in addition to the popularity of electric vehicles, the fuel economy of traditional gasoline engines will be greatly improved: "For example, the new Mazda6 has reached the target value set by us in 2019."
EPA revised fuel consumption test manual released at the end of the year. In view of the fact that some brands such as Ford, Hyundai, Kia and Mercedes-Benz have exaggerated vehicle fuel economy, the US Environmental Protection Agency (EPA) is developing more stringent fuel consumption. Test methods, it is expected that the new method will be officially introduced at the end of the year. The new method combines some of the changes that have been made a few months ago to make the test results closer to the level of fuel consumption that consumers actually drive.
It is reported that the biggest improvement of the new method is to increase the deceleration test under certain circumstances, that is, to collect data such as the rolling resistance and the friction of the transmission system when the vehicle travels at a speed of 120 km/h.
Another major change is to make up for a big hole – the EPA allowed automakers to test fuel on a single model only, and then the data could be applied to the same power system and other models belonging to a uniform weight class, such as last year being asked to change This is the case for the 2013 Ford C-Max with fuel consumption data.
At the same time, the agency will continue to expand the review of fuel consumption levels reported by automakers, which will prompt companies to review the fuel consumption of registered models to avoid "middle strokes."
