“…The WLTC-NEDC quotients were 0.94 and 1.04, respectively, for the Euro 6 D DPF and G-DI vehicles tested. This is consistent with Pavlovic (2016) and Marotta (2015). All the vehicles tested produced 2 to 5 times fewer CO and HC emissions during the Artemis average cycle than during the NEDC cycle.…”

“…Similarly small differences in the CO 2 emissions between the WLTC and the NEDC were reached in [35] when (as is also the case in this work) the same test mass for both cycles was applied to isolate the vehicle speed profile effects. On the other hand, when the whole test procedure is under investigation, and not just the cycle speed profile [18,33], the results may be different, with the vehicles exhibiting higher CO 2 emissions during the WLTP compared to the NEDC. …”

“…By doing so, we can eliminate all other test-procedure-related differences and isolate the vehicle speed-profile effects. Of course, for type approval purposes on the chassis-dynamometer, each test schedule is carried out according to the specific test procedure (as outlined in the relevant regulatory documents), and the obtained results should be different from the ones presented here, as the basis for the comparison is not the same (e.g., different gear-shift strategy, vehicle test mass, temperature of the test) [33,34].…”

“…Therefore, it is expected to lead to an increase of the overall CO2 emissions, as already reported in literature for vehicles equipped with conventional powertrains [31,32] This section provides an additional contribution, analyzing the impact of the new TA procedure on a test case vehicle representative of current state of the art of the hybrid technology.…”
