After the discovery of the falsified nitrogen oxide values in millions of cars could be followed by another scandal. The vehicles, according to a new study by the environmental researchers network, ICCT a result of the excessive gasoline consumption and CO2 emissions.
The organization, which had uncovered the exhaust-scandal at VW-diesel vehicles in the U.S. in 2015, announced in the presented analysis, the average deviation between the actual driving values and official information of the manufacturer of 42 percent. The ICCT began the time series for fuel consumption in the year 2001. At that time, the average deviation of all the included car models amounted to only 9 percent.
“All data sources confirm that the gap between the manufacturers’ published fuel consumption and the actual customer consumption has reached a new high,” said ICCT-member Uwe Tietge. Because of the direct coupling of the fuel-consumption and CO2-emissions of the affected drivers could have impacted the climate of a lot more than I thought.
The main cause of the “discrepancy” see ICCT-Europe-in-chief Peter Mock to the fact that the auto companies “take advantage of increasingly systematic use of loopholes in the existing regulation”. So many for the test bench used cars would be optimized specifically for the test situation. On the road you would have values of some of the other consumption.
According to the scientists fed the data for about a Million cars in the investigation. Despite Differences in the driving of the owner’s behavior was due to the large number of individual observations to allow for consistent results, which indicated a clear Trend for the fleet of new vehicles.
After 2008, the values
Savory, and fell from the point of view of the ICCT: at the Latest after the EU agreement on binding CO2 rules in the auto industry in 2008 fell, the official values of CO2 “significantly faster” – but the real emissions of the greenhouse gas, apparently not to the same extent.
“Particularly large deviations are observed in the Premium Segment, where in reality the fuel consumption of certain vehicle models, on average, more than 50% higher than specified by the manufacturer”, is critical of the organization. Also in the case of hybrid cars, the gap had risen significantly the last. Especially at the Start of a new model generation, the increase is often by leaps and bounds. “In the Wake of the achieved CO2 reductions are, since 2001, in reality, only about half as high as expected on the basis of the certification values.”
gap between specification and measurement
For their analysis, the authors of the study and details of private car users in specialized consumption sites, the tank data of leasing companies, road tests, journals, and measurements of car clubs. Never the “gap between official and actual consumption was” so big, they stressed.
Tests of the ICCT, and West Virginia University to the Emission of nitrogen oxides from diesel cars in the USA had led to the fact that the local authorities were on the manipulations of VW’s attention. In September 2015, the outbreak of “diesel-gate”affair, advanced an entire industry into the twilight. At VW, it has led to billions of reserves for penalties and legal costs, the group plunged into a crisis.
impact on Car tax
so Far, the scandal revolved mainly around health, harmful nitrogen oxides (NOx) and the greenhouse gas CO2 and the associated financial impact on the Car tax.
In the spring, was noted by the Federal motor transport authority (KBA) according to measurements in the case of NOx, also in the case of CO2, eye-catching data. According to reports, a significantly higher CO2 confirmed in the summer, then part-values. “The investigations are not yet complete”, – was stated from the Federal Ministry of transport. VW announced that the data for two models. Also Audi was last under pressure.
The German Association of the automotive industry (VDA) had stressed for the German manufacturer recently: “The transport sector makes a significant contribution to CO2 reduction.” Mock said, including CO2 and fuel economy a variety of legal and semi-legal slip was holes. “There are also no strong authority, and not a good test procedure.”
ADAC wants sharper measurements
The ADAC is in favour of significantly stricter and more consistent rules for new emissions tests, so that the gap between the consumption values in the brochure and on the road closes.
“is required by The policy, the Standards of the new measuring method is not more to be interpreted from 2017 so strictly that such “optimizations” are possible,” said the motorist club on Thursday with a view to the most recent data from the environmental organization ICCT.
