Reporting is spotty.
' figured, anyone that interested would look into it.
The 2007, Cd 0.21, Ford/Buckeye, Fusion 999, hydrogen fuel cell, Bonneville LSR car was an EV.
Cd 0.34, minus 0.024 for the cooling gives a Delta- 7.05% drag reduction with respect to the ICE Fusion it's based upon.
Spirit was simulated as a zero-porosity BEV. In its cleanest configuration, the cooling drag deletion meant a 13.17% drag reduction.
Some BEVs are not liquid-cooled. The degree of body porosity and delta-Cd would have to be taken on a case-specific basis.
With respect to the IVECO, it's obviously possible to have a liquid-cooled BEV with zero- aerodynamic drag cooling and heat-pump systems.
Presently, there's not much being reported about it in the lay literature. And what is, is complicated by the presence of active shutters.
