IWG#8 decision: Calculation based WLTP Coast Procedure, No supplemental test

Recommendations

Due to insufficient progress because of:– Fundamental discussions on “cycle modification”– Ongoing discussions for the correct place (WLTP Eco Inno)– No proposal met everyone's interest

… the TF is running out of time !!!Consequently a decision is required on:1. Delay Coasting deliverables in Phase 2, but keep on working2. Cancel Coasting TF and restart if/when applicable3. Keep Phase1 timing but invest more and better focused resource
