The European test cycle for fuel economy and emissions may need to be taken out back, based on findings by policy group Transport and Environment.
According to Ward's Auto, T&E proclaimed the New European Driving Cycle "is not fit for purpose," finding the laboratory results reported by automakers and those uncovered in real-world scenarios have a gulf between them, one that has widened over time: 8 percent difference in 2001, 31 percent in 2013, and a predicted 50 percent by 2020 if no action is taken.
Per the group, the NEDC is "obsolete, unrepresentative of modern cars and driving styles, and full of loopholes that car makers exploit to produce better test results," as the lab results fail to account for external factors.
A replacement is in the works: the AECA is helping to develop the Worldwide Harmonized Light Vehicles Test Procedure, meant to replicate the real-world conditions the NEDC fails to account. The European Union would like the WLTP ready by 2017, but T&E clean-vehicles chief Greg Archer wants to see it sooner so that automakers can be stopped from "exploiting the flexibilities" in the current procedure.
