A recent study shows that there is a large gap between the fuel-efficiency declared by automakers and the real one, with the biggest divergence seen at German automakers.
The study was made by the non-profit International Council on Clean Transportation and shows that the real carbon emissions in new vehicles based on fuel consumption are with almost 25% higher on average compared with what automakers say and compared with 10 years ago. This report will add to the pressure from the EU reform for vehicle testing procedures to make sure that the advertised fuel-efficiency reflects reality.
This means that it will be harder for automaker to meet the tough EU carbon dioxide vehicle emissions target for 2020. BMW, for example, reported CO2 emissions for its new vehicles on average 30% lower than the real ones. VW’s Audi is the automaker with the second largest disparity, about 15% under the real CO2 emissions and Renault and PSA Peugeot Citroen is with about 16% lower than their vehicles on the road.
“This means that the actual fuel consumption experienced by the average driver is typically 25 percent higher than what is printed on the sales sticker,” Peter Mock, managing director of ICCT Europe, said.
