Analysis of vehicle emission measurements on the new WLTC, the NEDC and the CADC [PDF]
Transportation Research, Part D: Transport and Environment, 2014 Several studies have shown that the type-approval data is not representative for real-world usage. Consequently, the emissions and fuel consumption of the vehicles are underestimated. Aiming at a more dynamic and worldwide harmonised test cycle, the new Worldwide Light-duty Test Cycle is being developed.
