How to really clean a car? The car manufacturer Volkswagen has a very own idea. "Car wash, always and everywhere," promises the group in a Extra action on the website and offers discounts on auto-cleaners, and "sustainable". Elsewhere, it take a lot of car manufacturers with the clean Drive according to experts, however, still not very accurate.
The fuel consumption – and thus also to the emissions of greenhouse gases – were between the official figures and the real values are still the worlds, found a new study by the independent research organization the International Council on Clean Transportation (ICCT). The real fuel consumption of new Cars spent an average of 39 percent, higher than the vehicle manufacturers specified test fuel consumption, informed the organization that was also involved in the detection of the VW scandal, on Thursday.
The report is based on a statistical analysis of the data for more than 1.3 million vehicles out of a total of eight European countries. It is a question of new cars from the year 2017. The data are based on figures supplied by major leasing companies. But also information of fuel consumption, portals and specialist magazines were included in the calculations.
the consequences of The deviations are severe. Firstly, the higher CO2-complicate the values in the fight against climate change – the transport sector is lagging behind in the reduction of greenhouse gases anyway. On the other, more expenditure on fuel of around 450 Swiss francs per year for drivers of the organization, according to the average.
"For the first Time since 2012, we have noted a slight decrease in the gap between the official and actual consumption."Uwe Tietge, ICCT-researchers
However, the auditors noted in the statistics, a slight, but noticeable change. "For the first Time since 2012, we started with our annual evaluation of the fuel consumption data, we find a slight decrease in the gap between the official and actual consumption," says Uwe Tietge, one of the ICCT researcher and Co-author of the study. "Previously, the deviation increased from year to year."
eleven years ago, the real values were still 15 per cent. In 2013, there were already 25 per cent. Because fuel consumption and carbon dioxide emissions of a vehicle directly together, was, therefore, carried out only a part of the on the paper provided CO2 reductions.
The car companies have exploited loopholes in the regulation. The law is not prohibited.
As, indeed, in measurements as significant differences can arise, declare auditor for a large part with the whitewashing. The main cause of the discrepancy ICCT-Europe-in-chief Peter Mock sees the fact that the car would have exploited corporations use loopholes in the regulation. So many for the test bench used cars are optimized specifically for the test situation. The manufacturer could, for example, to prepare the tires of a vehicle specifically for the Test. You would be fully inflated, in the oven, hardened and profile ground, so you have a little more friction. The brakes were loosened. Air conditioning and all other consumers could be switched off.
the Law is not prohibited. It is not reflected but the real driving behavior, warns Mock. On the road the vehicles had values then, in part, very different fuel consumption. The ICCT researchers suspect that the increased public interest in the real-world emissions of vehicles as a result of the Diesel scandal has led to the decrease of the deviation. The pressure on manufacturers will increase in the coming years.
New commitments from 2021
at the end of December 2018, agreed by the European Commission, the EU Parliament and the EU member States on stricter CO2 targets for new vehicles. Therefore, the CO2 must decrease - emissions from new passenger Cars between 2021 and 2030, to 37.5 percent. "The legislature has learned from previous mistakes," says Mock. Because the manufacturer will be required as of 2021, now, to monitor the real fuel consumption and real CO2-emissions of their cars by a fuel consumption measuring devices.
The researchers have doubts as to whether the trickery really stop.
The automotive Association VDA, rejected the criticism. Emission values of vehicles in the laboratory and on the road are fundamentally different. Conditions of real traffic, such as weather, traffic or topography, could simply not be tested. In addition, the individual driving style have a significant influence on the fuel consumption. Now applicable more stringent test procedure would reduce the discrepancies. The consumer can get more reliability.
The ICCT has doubts as to whether the trickery really stop. The environmentalists would still have a "watchful eye" on the exhaust emission measurements in the industry, announced Mock and called for tougher rules. The EU Commission should, if possible, to develop a method to punish the manufacturer, the provided by unrealistically low figures for consumption is an advantage. The only way it could succeed, the deviation is further reduced significantly. (Editorial Tamedia)
