4 Agenda item 3.a & 3.b Status of the work related to buses and coaches (M3 vehicles 7.5 tons) 4/ 17

5 Status Quo Buses and Coaches (M3 7.5 tons) (1/3) Extensive work already performed under previous DG CLIMA contract ( LOT4, B&C board meetings ) Main open technical issues: VECTO AT model, VECTO Auxiliary model, provisions for air drag Main open legislative issues: classification scheme (ACEA draft based on 3 main groups), handling of multistage vehicles ACEA updated the proposal for classification scheme für M3 vehicles 7.5 tons in March 2018 (61 groups in total with 28 active in VECTO) Analysis of implications of updated classification scheme as well as sales numbers and CO 2 shares ongoing Data from 4 ACEA manufacturers delivered data so far. Open: 1 ACEA OEM, 2nd/multi-stage OEMs Tbd: CLCCR/CLEPA to contribute with sales numbers? 5/ 17

6 Status Quo Buses and Coaches (M3 7.5 tons) (2/3) Current provisional figures: Share CO 2 from M3 vehicles 7.5 tons GVM approx. 6.5% of total HDV Share CO 2 from M3 vehicles from 5 to 7.5 tons GVM below 0.2% of total HDV Current ACEA classification proposal covers 100% of M3 vehicles 7.5 tons To be discussed: Several combination of vehicle group and vehicle technology covered by only 1 or 2 OEMs reconstruction of sales numbers of competitors possible even from consolidated datasets Can consolidated data on group level be forwarded by TUG to DG GROW? (option not to publish any data in reports and official meetings) 6/ 17

7 Next steps Topic Until Finalise analysis of sales numbers and CO2 shares Technical discussions with manufacturers, main topics: Implications of the updated classification scheme Technical topics (AT simulation in VECTO, Bus auxiliaries, Air drag etc.) How to handle multistage vehicles (separate meeting?) June 2018 Proposal for classification scheme (COM) Analyse technical feasibility and resources needed for the implementation in VECTO and in 2017/ Elaborate open issues to include buses and coaches Start 09/2018 Draft extensions for legal text Start 09/2018 Feedback loops until end of project Feb Implementation in VECTO software and pilot phase are not covered by the actual project 7/ 17

8 Agenda item 3.e Challenges and options for including HDVs <7.5t in VECTO 8/ 17

9 Task Elaborate information as basis for decision on classification scheme for M1, M2, M3, N1, N2 vehicles possibly to be added to 2017/2400 (VECTO) Existing classification schemes Shares in new registrations Shares in CO2 emissions from all HDVs Technological issues Effort to extend 2017/2400 9/ 17

10 Existing Regulations Type approval for pollutant emissions HDV CO2 certification is related to 595/2009 Reg. 715/2007 Reg. 595/2009 Chassis dyno test Engine test Type approval method depends on RM of completed vehicle Extension to its incompleted vehicles if RM+ body work expected >2610kg Extension to variants of completed veh. > 2380 kg at request of manufacturer. Needs CO 2 +FC measured acc. 715/2007 RM = > <2840 kg Extension to variants < 2840t RM at request of manufacturer. RM Reference Mass = mass in running order -75kg (driver) +100kg 10/ 17

11 Existing vehicle classifications Class (UN-ECE) Max. Mass (mm) RM for Reg. 595/2009 N1 3,5 t RM >2610 N2 3,5 t< mm 12 t RM >2610 N3 > 12 t RM >2610 M1 M2 M3 mm 3,5 t < 8 seats + driver 3,5 t < mm 5 t >8 seats + driver > 5t >8 seats + driver RM >2610 RM >2610 RM >2610 VECTO applicable to vehicles type approves according to Regulation 595/2009. This covers all vehicles with reference mass > 2610kg, with exceptions as discussed before. 11/ 17

12 Relevance of the different classes Data collection: *New registrations provided by ACEA. *Km/(veh.-year) from national statistics *gco 2 /km from PEMS tests, Chassis dyno tests and VECTO simulations. orders of magnitude ok, uncertainties remain Analysis, 2016 data, EU New vehicle registrations CO2 Emissions vehicles p.a. % veh. 1000t CO2 p.a. % CO2 N2&M2; >3.5 < 5t with LDV cert % % N2&M2; >5 < 7.5t with LDV cert % 0 0.0% N1 & M1 with HDE % % N2&M2; >3.5 < 5t with HDE % % N2&M3; >5 < 7.5t with HDE % % N2 &N3 >7.5 <16t % % N3 >16t % % M3 >7.5t <16t % % M3 > 16t % % Total N and M with HDE % % Total N2,M2, M3 with LDV cert % % Total % % Result overview: N1,N2,M2,M3 < 7.5t with HDE certification: ~16% of new HDVs ~2.6% of new HDVs CO2 (lower mileage and lower l/100km than larger HDVs) 12/ 17

13 Issues with strict max. mass definitions for classifications Examples for trucks offered with different max Veh Mass between 2.6 and 7.5t Van Flatbed/Tipper Chassis Make Model Max. permissable mass in t, min., max. DAF LF Fiat Ducato Ford Transit Fuso Canter Isuzu N Daily Iveco Eurocargo MAN TGL Atego MB Sprinter Opel Movano D Renault Master Maxity VW (MAN)Crafter (TGE Examples on next slide Above max mass of ~5.5t almost all vehicles have HD engine certification MT, AMT and AT transmissions offered as options. 13/ 17

14 Example for variabilities in a model offered From IVECO Daily catalogue: Wheel base (mm) Vehicle length (mm) Loading space lenght (mm) Loading space width (mm) Hight and load volume Max. Mass [t] Splitting trucks <7.5 t in several classes may be useful for possible future CO 2 limits; from perspective of vehicle technologies, there is no exact cut point. 14/ 17

15 Possible classification scheme All vehicles with HD engine certification considered, exceptions discussed later. Characteristics which may be considered for classes 1) Maximum mass and / or reference mass Many models are offered within a broad range of max. mass. Narrow classification according to max mass and/or reference mass is thus difficult since it may allocate similar vehicles in more than one class. One or two classes for N2: RM>2.61t (to mm<5.5t) to mm<7.5t for M2 (<5t) and M3 (>5t to <7.5t) one class for each seems to be ok 2) Design: Box wagon.air drag test delivers real C d xa value, better aerodynamics than vehicle with extra body possible Chassis.as for rigids >7.5t a norm body has to be defined for air drag tests 3) Axle configuration: 4x2 seems to be standard, 4x4 possible, further demands to be discussed. 4) Other options or demands? 15/ 17

16 Possible implementation scheme in VECTO Reference mass [kg] All vehicles with HDE certification (RM >2610 kg and exceptions) Vehicles where almost all have a HDE certification (mm > 5.5t) Already in VECTO Chassis dyno >5.5 t >7.5t Max. vehicle mass [t] 16/ 17

17 Necessary extensions in VECTO Included class Vehicles with obviously only HDE certification due to max vehicle mass (>5.5t max. mass) Vehicles with mandatory HDE certification according to reference mass (>2610 kg) All Extensions needed Generic data for auxiliaries and loading. Generic bodies for air drag test and regulation for box wagons. Generic MT, AMT, AT shift models to be checked. Test cycles to be checked. Definition of additional classes below 5.5t. Generic data for auxiliaries and loading per class. Generic MT, AMT, AT model to be checked. Additional test cycle for smaller vehicles? New technologies to be added in VECTO? Other issues? 17/ 17

18 Necessary Extensions in the Regulatory Text Included class Annex I Classification Annex III Vehicle input information Annex IV Manufacturer's record/customer information file Annex V Engine Annex VI Transmission and Annex VII Axle Annex VIII Air drag Annex IX Auxiliary data Annex X Tyres Extensions needed Draft classification scheme text Update for additional vehicle parameters for VECTO and for the manufacturer's record/customer information file Update to include additional VECTO results or vehicle parameters No need for amendments for vans and small buses yet identified Open yet, if additional transmission or axle types need to be implemented, e.g. double clutch transmission Constant speed tests assumed to be applicable. Description of generic correction factors, family concepts and default bodies to be extended Extension of technologies and generic data Update for additional tire dimensions 18/ 17

19 Summary; options to extend VECTO to HDV < 7.5t Relevance of N2, M2, M3 3.5 and 7.5 t: ~ 12% from HDVs ~ 3% from HDV CO2 LOT 4, SR7 results suggest, that >~5.5t vehicle missions are quite similar to trucks >7.5t (VECTO class 1, urban and regional delivery). Towards lower masses we assume increasing shares of low loading factors and mission profiles being different to VECTO class 1 (>7.5t). But yet no data on loading and driving behaviour available for vans and small busses < ~5.5t. Logical options for VECTO extensions towards <7.5t: a) Add HDV with >5.5t max. mass b) Add also vehicles from 3.5t to 5.5t c) Add all vehicles with HDE certification (others get WLTP value) Stepwise extension from option a) to c) possible. Option b) difficult, since vehicles certified acc. 715/2007 concerned also. Number of OEMs involved is increasing from a) to c) 19/ 17

20 Proposal TUG for extension of VECTO to HDV < 7.5t Due to limited duration of the actual project, we suggest following steps until March ) Start to elaborate details necessary to cover vehicle >5.5t to < 7.5t (generic data, methods, extensions in regulatory text, list of necessary extensions in software). Target: draft for this class at end of project. 2) Further analyse usage patterns and market situation (overlapping LDV and HDE certifications) especially for vehicles max Mass < 5.5t 3) Elaborate options for fair and cost efficient CO2 monitoring for vehicles where both, LDV and HDE certification is possible today. Targets: Collect more data for typical mission profiles which users?) Decide if all veh. with HDE certification shall be covered in VECTO If yes, decide on further sub-classes needed. Decide if/how HDVs with LDV certification (715/200/) shall be included in CO 2 monitoring 20/ 17
