ICCT study finds increasing discrepancy between type-approval and real-world fuel consumption in European cars

Green Car Congress

A new study by the International Council on Clean Transport (ICCT) has found that the gap between type-approval and “real-world” fuel consumption / CO 2 values for European cars increased from about 8% in 2001 to 21% today, with a particularly strong increase since 2007. Only CO 2 values are reported; the conversion factors used are 2.43
