• Interpretation of open issues
2WLTP 2nd act
Procedure for the correction of test results
• The Correction procedure of speed and distance is finalised.
• However, in the course of the activity on this item, some stakeholders
have provided evidence that it is necessary to add the concept of Driving
Index, which is a mean (more accurate than the current tolerance band
above and below the theoretical speed profile) to assess the acceptability
of a driving test.
• Once a driving test is accepted (on the basis of the corresponding Driving
Indexes), then the correction of speed profile and distance can be carried
out.
• The WLTP 2nd act WG is now agreeing on the most appropriate set of
Driving Index ranges to minimize the possibility to have a false valid (or
false invalid) driving test. The statistical analysis is being carried out by
the JRC.

Transparency provisions
• The task force in charge of this item is working on two
different aspects: list of transparency parameters, handling
of this info.
• The list of parameters is almost finalised
• The handling of this info and the link with the ISC-Market
Surveillance scheme is currently being developed.

Transparency provisions
• It is worth reminding that the Transparency provisions
are needed for the new In-Service Conformity/market
surveillance (ISC/MS) scheme that is being prepared in
RDE 4.
• However, while the ISC/MS scheme will involve a limited
number of vehicles on the market (sayWLTP 2nd act

Adaptation of the Evaporative test to WLTP
• During the past months a new EVAP procedure, developed
at UNECE level, has been adapted to the WLTP testing cycle
and complemented with some elements, like testing of
hybrid vehicles and provisions for sealed tanks.
• Therefore, the Evaporative testing procedure in the WLTP
1st act (Commission Regulation (EU) 2017/1151) will be
amended in WLTP 2nd act to reflect those changes.

12Article 16a (1)
In Regulation (EU) 2017/1151 the following Article 16a is added to Regulation (EC) No
692/2008, setting the rules for the transitional period between the start of application of the
Regulation (EU) 2017/1151 and the repeal of Regulation (EC) No 692/2008 (both Regulations
will be in force between 2016 and 2022):
"Article 16a
Transitional provisions
With effect from 1 September 2017 in the case of categories M1, M2 and category N1 class I vehicles,
and from 1 September 2018 in the case of N1 vehicles of class II and III and category N2 vehicles, this
Regulation shall only apply for the purposes of assessing the following requirements of vehicles type-
approved in accordance with this Regulation before those dates:
(a) conformity of production in accordance with Article 8;
(b) in-service conformity in accordance with Article 9;
(c) access to vehicle OBD and vehicle repair and maintenance information in accordance with Article
13;
This Regulation shall also apply for the purposes of the correlation procedure set out in
Implementing Regulation [XXX][PO please insent reference]."
(3) Annex I is amended in accordance with Annex XVII to this Regulation.
Apparently this wording does not allow for extensions of type-approvals granted under
Regulation (EC) No 692/2008 during the period between 1 September 2017 (or 1 September
2018) and 1 September 2018 (or 1 September 2019), which is the date of application of
WLTP to all new type-approvals. 13Article 16a (2)
• The Commission believes that the text allows for extensions
of type-approvals between the dates of application to new
type and to new vehicles and we propose to interpret the
text in that sense
14Definition of emission type for Bi-fuel and
flexifuel vehicles
• Bi-fuel and flexifuel vehicles will fall under two interpolation
families. However, the Commission believes that this should
not require two type-approvals, but only one, covering both
fuels.
15Gear Shift provisions
• For the type approval of vehicles under WLTP in EU the
Gear Shift procedure to be adopted is the one described
in Regulation (EU) 2017/1151.
• If for a given vehicle the manufacturer demonstrates to
the Technical Service that the Gear Shift Strategy
provided by Regulation (EU) 2017/1151 is not feasible
then is should be allowed to use the GS procedure
described in the GTR 15 Amendment 3 (on the basis of
the fact that this version will be incorporated in WLTP
2nd act asap).
16Wording of the Ki provisions
• According to point 1.1. of Appendix 1 to sub-Annex 6 to
Annex XXI, alternatively to carrying out the test procedures
defined in this Appendix, a fixed Ki value of 1,05 may be
used for CO2 and fuel consumption.
• There may be the need to clarify that the fixed Ki value of
1.05 for CO2 and fuel consumption is not intended to
exclude the regulated pollutants from the scope of the Ki
provisions, but an alternative for CO2 and fuel consumption
only.
17CoC of LDV and HDV
Some requirements of the CoC that are relevant for the
application of the WLTP emission type approval procedure
were amended. However, these amendments of the CoC have
an effect also on vehicles that fall in the scope of Regulation
595/2009, where they are not relevant (for example, WLTP
requires the frontal area of the vehicle for the application of the Road
Load Matrix approach, so the item in the CoC on height or
permissible height is consistent with the requirement for frontal
area).
The requirements which have no use for vehicles that can be
approved as HDV according to Regulation 595/2009 should be
deleted in this context.
18(no) CO2 for representative vehicle of
Road Load Matrix family
• There is no need for measuring the CO2 of the
representative vehicle of the Road Matrix family,
and therefore this should be deleted.
19Total CO2 range of an interpolation family in
case of extrapolations
• Point 1.2.3.2. of sub-Annex 6 states that the interpolation
line may be extrapolated to a maximum of 3 g/km above
the CO2 emission of vehicle H and/or below the CO2
emission of vehicle L.
• This extension is valid only within the absolute boundaries
of the interpolation range specified in the same point:
between a minimum of 5 and a maximum of 30 g/km or
20 per cent of the CO 2 emissions from vehicle H,
whichever value is the lower.
