ndly, Phase 2 includes changes in the evaluation of aerodynamics. To reflect the in-use aerodynamic performance of combination tractors, the wind averaged coefficient of drag is used in the GEM model instead of the no-wind (zero yaw) value used in Phase 1. Finally, for Phase 2 the simulation of the transmission in GEM is also improved, this could increase the CO2 emissions and fuel consumption figures when compared to those obtained with the Phas...
