1 AECC PHEV test programme RDE working group 10 March 2017

2 Test programme set-up Objective: measure the real-world behaviour of a market representative Plug-In Hybrid Vehicle Vehicle C-segment, 1.5l class GDI engine Euro 6b certified Rental car ~10k km Mileage 4 Driving modes: Electric, Hybrid, Charge and Sport Official electric range: 50km Similar vehicle as 2016 AECC GDI programme (tests without and with GPF presented in RDE working group meetings) AECC PHEV test programme RDE working group 10/03/2017 2

3 Test programme set-up Measurement details At Ricardo (UK) All tests on market fuel HORIBA PEMS OBS one: gaseous and PN Test Matrix All 4 driving modes Variation in initial battery SOC On-road RDE tests (finished) and on-dyno RDE tests (planned) Repeat some tests with coated GPF retrofitted AECC PHEV test programme RDE working group 10/03/2017 3

9 PN emissions of PHEV vs. reference GDI Test in electric mode with 100% SOC has zero urban RDE tailpipe PN, other PHEV results are between reference GDI with GPF and w/o GPF AECC PHEV test programme RDE working group 10/03/2017 9

10 PN emissions of PHEV vs. reference GDI Test in electric mode with 100% SOC has zero urban RDE tailpipe PN, other PHEV results are between reference GDI with GPF and w/o GPF Test in electric mode with 100% SOC has similar total RDE tailpipe PN after cold IC engine start in middle of trip AECC PHEV test programme RDE working group 10/03/

11 PN emissions of PHEV vs. reference GDI Test in electric mode with 100% SOC has zero urban RDE tailpipe PN, other PHEV results are between reference GDI with GPF and w/o GPF Test in electric mode with 100% SOC has similar total RDE tailpipe PN after cold IC engine start in middle of trip AECC PHEV test programme RDE working group 10/03/

12 NOx emissions of PHEV vs. reference GDI All results below Euro 6d NTE limit Euro 6d NTE limit (CF=1+0.5) Euro 6d NTE limit (CF=1+0.5) AECC PHEV test programme RDE working group 10/03/

13 NOx emissions of PHEV vs. reference GDI All results below Euro 6d NTE limit PHEV NOx emissions with 100% SOC are lower than reference GDI Euro 6d NTE limit (CF=1+0.5) Euro 6d NTE limit (CF=1+0.5) AECC PHEV test programme RDE working group 10/03/

14 NOx emissions of PHEV vs. reference GDI All results below Euro 6d NTE limit PHEV NOx emissions with 100% SOC are lower than reference GDI Cold IC engine start in middle of trip can cause higher emissions (e.g. for Electric, 55%) Euro 6d NTE limit (CF=1+0.5) Euro 6d NTE limit (CF=1+0.5) AECC PHEV test programme RDE working group 10/03/

15 CO emissions of PHEV vs. reference GDI Most of the PHEV urban and total RDE emissions are higher than the reference GDI AECC PHEV test programme RDE working group 10/03/

16 CO 2 emissions of PHEV vs. reference GDI PHEV shows lower tailpipe urban CO 2 results AECC PHEV test programme RDE working group 10/03/

17 CO 2 emissions of PHEV vs. reference GDI PHEV shows lower tailpipe urban CO 2 results Most of the total RDE tailpipe CO 2 results are similar to the reference GDI AECC PHEV test programme RDE working group 10/03/

18 CO 2 emissions of PHEV vs. reference GDI PHEV shows lower tailpipe urban CO 2 results Most of the total RDE tailpipe CO 2 results are similar to the reference GDI Electric range on RDE trip: ~35km AECC PHEV test programme RDE working group 10/03/

19 Summary Preliminary results of the ongoing AECC PHEV test programme 1 Euro 6b C-segment vehicle Raw data, no RDE post-processing Comparison to a reference GDI PHEV emissions are lower when fully charged, enabling local zero tailpipe emissions Some driving mode and initial battery SOC combinations had higher emissions, also in electric mode The cold IC engine start in the middle of the trip has a significant impact AECC PHEV test programme RDE working group 10/03/
