1. 1 WLTP Open Issue Phase 1B Issue: Number of testsOIL#27. Starting note for IWG Meeting#7 Geneva, 4. 6. 2014 WLTP-07-10-rev1e

2. 2 Page 2 If the emission result is above 70% of its limit value  second test If first or second test is above 85 % of its limit value  third test emissions of up to 110 % of the limit value could be used Example : (94+94+110 )/3 = 99.3 Up to three tests are necessary to show compliance with the limits gtr Annex 6, 1.1.1.2. Figure A6/1 CURRENT STATE – R83 PROCEDURE

3. 3 With the R83 procedure it is possible to type approve a vehicle with only one measurement. Therefore, measurements close to the emission limits had to be double checked. For WLTP type approvals, vehicles will be tested several times: Twice with vehicle-high und and -low for the interpolation of CO 2 values (type I) Once for a family in the ATCT In the European WLTP type approval process compliance with the limits has to be shown two to three times, regardless of the measured level in relation to the emission limit. Additional measurements required by values close to the emission limits (R83 procedure) provide no higher significance / only statistical information. Page 3 MOTIVATION

4. 4 ICE vehicles: 1.1.1.2. of annex 6 If the emissions are above 90 % of the respective pollutant emission limit, compliance with the limits shall be demonstrated with a second Type I test for vehicles in one CO 2 vehicle family. Each test shall comply with the pollutant emission limits. Compliance has to be shown with at least two of the following tests Type 1 test with vehicle-high configuration Type 1 test with vehicle-low configuration Requirement for PHEV vehicles: “Each CD and CS test shall comply with the pollutant emission limits.” For Charge Depleting tests of PHEV: “The paragraph shown in §1.1.1.2. of annex 6 shall not be applied for the emission evaluation in case of OVCHEV Charge Depleting testing.“ Page 4 PROPOSAL

6. 6 The structure of future regulation delivers a clear picture of the emission compliance of a tested family through various types of emission tests. It is required to meet the standards with Type I Tests at 23 °C with vehicle-high and – low configuration and with ATCT at 14 °C (Europe). This family based approach of emission compliance verification no longer requires the averaging of emission results R i as of R83: (R i1 + R i2 + R i3 )/3 < L  WLTP: Each test shall comply with the criteria pollutant emission limits. No criteria in Japan: Every test below 100% of the respective limits is valid The 90 % criteria follows the requirement of the EPA of an additional test, if the level of 90 % of the respective standard is reached (so called high cert level) This approach covers Type I tests of all vehicle with ICE and PHEV Page 6 JUSTIFICATION

7. 7 BACKUP

8. 8 US High cert level: High emission levels. Any certification level (test level adjusted by the deterioration factor, or test level with aged components installed) is 90 % or more above the applicable standard. If more than one test was performed for any procedure, only the last test is considered for this criterion. Page 8 CAP 2000 GUIDANCE
