Agenda» Review High Level Issues in a Nutshell» Look at Changes from Phase 1 Including Test cycles, vocational bins» Review Assumptions on Tech» Next Steps
HD Truck Fuel Economy Task Group Goals: In advance of rule development, discuss key issues for industry and users Provide platform for feedback through rule-making Make sure beneficial fuel saving technology included in rule design Seek areas of agreement; identify key areas of concern Work collaboratively to develop recommendations Provide feedback to agencies 4
HD Fuel Economy Phase 2 Draft rules (NPRM) released June 19 Formal in Federal Register July 13 60-day comment period to Sept 11, 2015; will include workshops Final Rule April 2016 Rule horizon proposed 2021-2027 EPA/NHTSA believe there is payback for rule technology
Highlights in a Nutshell Outlines several alternatives Preferred alternative (Alt 3) runs 2021-2027; more aggressive alternative ends at 2025 with same stringency Adds trailers for first time (starts 2018) Technology-forcing Keeps engine and full vehicle certification; adds powertrain cert Adds three bins for vocational urban, regional, multi-purpose Enhances test procedures to better reflect real world speed ranges, grades, idling
5 Alternate Rule Paths Agencies prefer Alternative 3 Alternative 4 same stringency, but three years faster they view this as maximum feasible alternative but want comments
Summary of Preferred Alternative
Directional Summary Phase 1 & 2 From ICCT
Summary of Rule Benefits
Key Issues Engine Certification maintained however, actual engine data now included in GEM Simulation model and is interactive component of Vehicle Certification Engine test changed to better reflect real-world conditions GEM model now allows for unique engine, transmission, drive axle and tire radius inputs Powertrain data from testing can be input Includes more innovative tech defaults (lightweight materials, auto tire inflation, advanced cruise control, workday idle reduction, reduced axles)
SET Modes New Weighting to Reflect Engine Speed Changes Phase 1 Phase 2
Vehicle Drive Cycles Include Grade Minimum grade 2.1%; max 2.4% 30% of cycle includes grades agencies feel Phase 2 standards more rigorous with grade in test cycle Cycles now distance based, not time based (allows vehicles to vary speed but cover same distance)
Vocational Test Cycles Idling also built into cycles will use several cycles for tractors and for vocational vehicles NREL assessing whether to propose additional idle time in vocational cycles Most vehicles will be considered multi-purpose unless meet special provisions to be assigned to Regional or Urban
Additional Tech Alternative fuels/nat Gas Nat gas engines certified based on how used (not combustion type) Must meet diesel tailpipe standards for C02, not including fuel life cycle Nat gas required to have closed crankcase no venting Want comment on this (upstream emissions NG, electricity) Advanced technology (hybrid, electric) No extra credits in Phase 2 agencies assume they will be part of compliance solution Want comment on this issue 15
Additional Tech Innovative technology Now called off-cycle those things not captured in powertrain or simulation tests Already building in default credits for lightweight materials, advanced cruise control, auot tire inflation, workday idle reduction, axle configuration but different inputs can be submitted with test results E-PTO and other worksite solutions can be includes will maintain e-pto test process Collision avoidance systems NOT allowed
Tractor Trailer Class 7-8
Trailer Rule Summary
Vocational Rule Summary
HD Pickups and Vans Summary
Cost Assumptions by Vehicle
Payback Assumptions Roughly matches assessment done by ICCT for tractor trailers, and CALSTART soon-to-be released fleet study
Tractor Engine Assumptions Not large assumptions for Waste Heat recovery on engines
Tech Adoption Class 7/8
Tech Adoption 7/8 Contd
Assumptions: Hybrid 10% adoption; Start-Stop 70%
HD Pickups & Vans Tech Adoption Assumptions
Observations Well thought out and argued rule more complete than Phase 1 Reduction in fuel use/carbon in Alt 3 for Class 8 achieves near 40% reduction from beginning 2010 baseline roughly on glideslope for climate stability Vocational and Class 2B reductions seem not as tech forcing at first view Payback assumptions seem reasonable from CALSTART separate analysis on fleet benefits (to be released in next few weeks) Large areas where EPA/NHTSA do want comments CALSTART will be coordinating and providing comments with industry, fleets
Open Discussion
Next Steps Workshops to be Set Chicago Aug 6; LA Aug 18? CALSTART working to coordinate, encourage industry comments at work shops and in comments to agencies Will coordinate key sub sector comments Deadline for comments September 11, 2015 Can be filed electronically Provide additional thoughts, comments and feedback to CALSTART bvanamburg@calstart.org and agilde@calstart.org
