I perused the 1995 Sunrayce Technical Report again last night.
They made mention that with one of the George Washington University cars. When full wheel fairings were added, the overall drag was reduced over 34% (a 17% 'fuel' savings right there).
Hucho says that with low-drag vehicles,the wheels can constitute 50% of the drag.
Only more perspiration will tell!
